AB  - Significant amounts of crop diversity, especially in out-crossing species like maize (Zea  mays  L.)  is,  are  often  distributed both between and within related groups of accessions. Thus, a detailed characterization and classification of gene bank accessions should be performed prior to use of the best of them for introgression programs to enlarge the genetic base of the elite germplasm pool. Based on performances per se, 40 landraces were chosen out of the wide pool of Western Balkan landraces, previously clustered into 11 homogenous groups. The objective of this study  was  to  evaluate  the  heterotic  pattern  of  landraces  in  testcrossing  with  three  divergent  elite  testers  L217,  L73B013 and L255/75-5. According to the results of a two-year trial conducted at four locations, landraces 1267, 1346, 197, 1569, 1509 and 2036 expressed the best general combining abilities (GCA) for grain yield. Landraces 1960, 642, 2006, 1945, 1346, 1569, 1450, 1534, 1509 and 1665 performed well in crosses to L217, while landraces 1960, 773, 1798, 1665, 632, 877 and 1569 gave the best results in crosses to inbred tester L73B013. In crosses to inbred tester L255/75-5, the highest heterotic effects were expressed by landraces 467, 773, 1346, 1534, 2249 and 288. Particular attention is to be paid to landraces 1346, 1569 and 1509, having simultaneously high GCA and specific combining abilities (SCA). A certain number of landraces expressed heterosis with two inbred testers, indicating existence of a new unrelated heterotic pattern within the local germplasm pool evaluated.

AB  - The narrow genetic base of commercial maize varieties emphasise the necessity for conservation, characterisation and utilisation of germplasm stored within gene banks. Broad genetic variability preserved in the Maize Research Institute Zemun Polje (MRIZP) gene bank, which includes accessions which originated from the Western Balkan, as a part of European corn-belt, is an exceptional source of desirable traits for enriching breeders' working collections for maize breeding under temperate conditions. Preliminary screening for abiotic stress tolerance, which marked 321 maize landraces, served as the first step in stratification process of selecting a smaller number of accessions from the entire gene bank local collection. After classification of these landraces into eleven homogenous groups, the objective of this study was to continue the stratification process of selection (as a second step), based on evaluation of agro-morphological traits of interest for breeding. The conducted evaluation highlighted 40 landraces with the best per se performances, important for breeding. Out of them, 28 early-maturing flint landraces with stiff stalks, low positioned ears, high yield potential and good general ear assessment could be considered as valuable source for their introgression into elite flint germplasm pool.

AB  - The influence of grain moisture content at harvest and at the moment of popping on popping volume and percentage of unpopped kernels was analysed. Four popcorn hybrids were studied. Hybrids were harvested when grain moisture content was: above 25%, between 20 - 25%, and below 18%. Each sample was popped at 20%, 18%, 16%, 14%, 12%, and 10% of grain moisture. All examined factors and their interactions significantly influenced both popping volume and percentage of unpopped kernels. The highest popping volume and the lowest percentage of unpopped kernels were observed at 14% grain moisture content. Hybrid ZP 608k had the highest popping volume and the lowest percentage of unpopped kernels at all treatments and overall. The lowest popping volume and the highest percentage of unpopped kernels were noticed for ZP 501k. The lowest percentage of unpopped kernels was observed in the last harvest term when grain moisture content was below 18%.

AB  - White maize had an important role in human nutrition throughout the Western Balkan region. A great number of farmers (approximately 86% in Serbia) still grow traditional white Open Pollinated Varieties (OPVs) for human diet. Out of 2217 maize landraces stored within Maize Research Institute "Zemun Polje" (MRIZP) gene bank, more than 700 are white kernel accessions. Eighteen white maize landraces, collected in the Western Balkan region in different periods, were selected for the present study. By the evaluation of agromorphological performances and the basic chemical composition of grain, the objective was to determine the importance of landraces conserved under in situ and ex situ conditions, to be used as the initial material for breeding. The idea was to determine whether the varieties conserved under ex situ conditions (collected from the same or different regions) distinguish from varieties permanently grown in the region of western Serbia. It was found that varieties permanently grown in the western Serbia were more similar to varieties of the ex situ collection from eastern Bosnia and Herzegovina than to varieties collected in western Serbia 50 years ago. The comparison between OPVs and modern white maize hybrids for the basic chemical composition of grain showed the significant potential of OPVs for nutritive grain quality improvement. Increased organic production creates new possibilities for more intensive incorporation of OPVs into this agricultural system. New opportunities for the cooperation and share of responsibilities among breeders, farmers and genetic resources managers are initiated, to be used for in situ maize genetic resources conservation improvement. More detailed characterisation and evaluation of the white maize landraces will offer an explanation of what has motivated our farmers to maintain the OPVs production through centuries, despite the availability of modern hybrids.

By the evaluation of agromorphological performances and the basic chemical composition of grain, the objective was to determine the importance of landraces conserved under in situ and ex situ conditions, to be used as the initial material for breeding. The idea was to determine whether the varieties conserved under ex situ conditions (collected from the same or different regions) distinguish from varieties permanently grown in the region of western Serbia. It was found that varieties permanently grown in the western Serbia were more similar to varieties of the ex situ collection from eastern Bosnia and Herzegovina than to varieties collected in western Serbia 50 years ago. The comparison between OPVs and modern white maize hybrids for the basic chemical composition of grain showed the significant potential of OPVs for nutritive grain quality improvement. Increased organic production creates new possibilities for more intensive incorporation of OPVs into this agricultural system. New opportunities for the cooperation and share of responsibilities among breeders, farmers and genetic resources managers are initiated, to be used for in situ maize genetic resources conservation improvement. More detailed characterisation and evaluation of the white maize landraces will offer an explanation of what has motivated our farmers to maintain the OPVs production through centuries, despite the availability of modern hybrids.",

AB  - Twenty-six maize landraces were tested in order to evaluate maize seedling performance as an index for drought tolerance in adult plants. Samples were subjected to polyethylene glycol-induced osmotic stress at the early seedling stage. Grain yield was obtained in field experiments under well-watered (OC) and a combination of drought and high plant density (HD) conditions. Osmotic stress caused a reduction in seedling growth (length, fresh and dry weight), and increase in the shoot and in particular the root proline contents in the majority of landraces, and variations in root peroxidase (POD) activity. Genotypes displaying more pronounced root growth reduction and higher proline contents exhibited decreased POD activity under osmotic stress. Direct positive correlations between the proline content and growth inhibition, and between the proline and soluble protein content were established. Correlations between the changes in POD activity and growth parameters were significant and positive, and significant but negative with the changes in the proline content. In the field, water stress led to a reduction in grain yield in all of the tested landraces. Correlations between grain yield from both experimental sets (OC and HD) and osmotic-induced changes in seedling root growth were negative, which was opposite to the highly significant and positive correlations between the changes in the seedling root proline content and yield. Also, genotypes with the highest seedling root proline content increase under osmotic stress, exhibited the highest stress tolerance index (STI) based on grain yield achieved under both field conditions. Our results indicate that lower changes in POD activity and especially an increased proline content after exposure to osmotic stress during the early seedling stage could be considered as useful indices to facilitate selection efficiency for drought tolerance in adult plants.

AB  - Significant genotype x environment interaction for quantitative traits, such is grain yield, reduces the usefulness of genotype means, over all environments, for selecting superior genotypes. AMMI model is a valuable statistical tool in identifying systemic variation contained in the interaction effect. Obtained data could be applied in maximizing yield potential in every environment based on both narrow and wide genotype adaptability, without the necessity of developing breeding programs for smaller targeted environments. Precise assortment of superior genotypes, with the assistance of AMMI model, leads to the better recommendation of newly bred hybrids, and thus increasing maize grain yield in a targeted environment. In this research genotype x environment interaction and yield stability of 36 maize hybrids of FAO 300-700 maturity group was investigating. The trial was set according to Randomized Complete Block Design (RCBD). Data were processed in order to obtain average estimates of grain yield, and yield stability was assessed by the method of AMMI analysis. The highest average grain yield was achieved in 2011 (11.62 t/ha), and the lowest in the most stressful and dry 2012 (6.90 t/ha). In the region Loznica L2 the highest average yield was noticed (13.81 t/ha), while at L7 (Sremska Mitrovica) average grain yield was the lowest (6.97 t/ha). Results of AMMI analysis gave precise recommendation for production of maize hybrids in certain environments, by determining winning areas of hybrids H20, H11 and H36. Medium early maturing and high yielding hybrids (H11 and H20) are therefore considered more favorable for production in environments with lower precipitation, while high yielding and more stable hybrids H21 and H35 are suitable for a wider range of environments. Hybrid H36 (FAO 700) showed its full potential at L2, and L3 which did not suffer from a lack of moisture. This hybrid also expressed its best potential in environments with favorable conditions.

AB  - In the second half of 20th century the awareness of importance of landraces for the future, led to organized collecting missions for numerous plant species. A total of 2217 maize (Zea mays L.) landraces, collected in the former Yugoslavia, are stored at Maize Research Institute (MRIZP) gene bank. During 2014, new collecting missions were organized in the eastern and western parts of Macedonia. According to collecting site and kernel type, 14 samples from the Faculty of Agricultural Sciences and Food, R. Macedonia were chosen for the comparison and identification of possible duplicates, through coupling with the 16 MRIZP gene bank accessions from the same area and kernel characteristics. Phenotypic characterization was done for 21 traits according to International Board for Plant Genetic Resources descriptors for maize. The Principal Component Analysis (PCA) identifies five PCs with Eigenvalue > 1, explaining 80% of the total phenotypic variation. The most discriminative traits with the strongest positive associations were tasseling and silking dates, plant height, leaf length and ear length. Compared to the ex-situ populations, the number of alleles and the number of specific alleles, showed a significant decrease in the in situ populations. Twelve unique alleles were detected in samples from MRIZP gene bank, and only four were found in new Macedonian samples. Cluster analysis of morphological and molecular markers distinguished groups of maize accessions with distinctive morphological traits and genetic profiles that will be useful for conservation, and management of gene bank collection, as well as for possible utilization in breeding.

AB  - Although seeds of many leguminous crops are rich in minerals, their availability to humans is limited due to antinutrients, e.g. phytic acid, which forms stable complexes with metal ions. In this context, 19 chickpea and 13 peanut local landraces were tested in order to determine concentrations of main antinutrients and promoters that affect the availability of mineral nutrients: phytic acid, glutathione, free soluble phenolics and yellow pigment, as well as mineral elements: inorganic P, Ca, Mg, Fe, Mn and Zn. Chickpea and peanut seeds are rich sources of mineral elements as well as promoters that improve their availability. High variability among the examined landraces presents the opportunity for their exploitation in breeding for increased bio-availability. This was particularly supported by the relatively low phytic acid concentration found in seeds of both species. Chickpea is richer in Ca, Fe, Mn and Zn than peanut, which is richer in Mg. Positive correlations between phenolics, yellow pigment and Zn in chickpea seeds, as well as between phenolics and Ca in peanut seeds could contribute to the improved bio-availability of these minerals. Peanut exhibited higher variability than chickpea in terms of potential bio-availability of mineral elements. Among chickpea landraces, C15 could be considered as an Fe source and C12 - as an Mn and Zn source. Among peanut landraces, P5 could be considered as an Mn source, P2 and P3 as an Mg source, P11 as an Fe source and P2 as Zn source. These genotypes could be recommended and used in biofortification programs.

AB  - In plant breeding programs, it is often necessary to cross genotypes incompatible in time of flowering. In maize, when the incompatibility in flowering period could not be overcome by different sowing dates, or by the ability of silk to preserve its fertility in 10-15 days, conservation of pollen could be of great importance. For many plant species, the appropriate methods for pollen management have been set up, including methods of collecting, desiccation, testing of viability and longevity, as well as for pollen storage. The longevity of pollen during its storage depends upon plant species, conditions at the time of pollen collecting, pollen moisture content, as well as upon storage temperature and duration. Even within the same plant species, different genotypes exhibit different level of viability preservation during the conservation. Although maize pollen belongs to a tricellular pollen group and rapidly loses viability under field conditions, its preservation is possible. According to the literature, pollen viability could be preserved for 30 days in the conditions of refrigerator (+4°C), while in liquid nitrogen (-196°C) up to 120 days. In the majority of studies, pollen viability was evaluated in the laboratory conditions, and the results obtained could largely be differed from those obtained under field conditions, due to impossibility to control a number of environmental factors. This experiment was conducted under field conditions in order to evaluate the ability of pollen from commercial maize inbred line L217, stored under the conditions of +4°C and -20°C, to pollinate maize inbred L73B013 and produce grain. Inbred L73B013 is sown in five sowing dates in order to ensure the longer presence of fresh silk. Pollen samples from line L217 were taken twice, and along with silica gel, stored in refrigerator and freezer. Each of successive pollination included five silks. Except for the expected good ear seed set when silks were pollinated with fresh pollen, the next successive pollination resulted in extremely poor ear seed set. Pollen stored in the freezer for one day completely lost vitality, while the pollination with pollen stored for three days resulted in one kernel per ear (for two ears). Pollination with pollen stored for four days resulted in one kernel per ear for only one ear. Pollen stored at + 4°C gave slightly better, but still very poor results. Compared to control, the percentage of seed set for pollen stored only for one day was 4.4%, being decreased to 0.2% and 0.4% for pollen stored for four and five days, respectively. Plants pollinated with pollen stored for 20 days did not give any grain. Such poor results may be a consequence of species specific properties of inbred L217, but also a consequence of failure in the manipulation of pollen. A highly sensitive point during the storage of pollen, especially in species with pollen sensitive to dehydration, such as the maize pollen, is the process of drying before its storing. Therefore, we concluded that the procedure of pollen desiccation probably was not adequate. With the aim of correcting the deficiencies observed, the experiment will be repeated in 2017.
AB  - U programima oplemenjivanja kukuruza, u slučaju kada se nekompatibilnost u vremenu cvetanja oca i majke ne može prevazići setvom roditelja u različitim rokovima ili sposobnošću svile da očuva plodnost 10-15 dana, čuvanje polena bi moglo da ima značaja. Cilj izloženih istraživanja je bio da se u poljskim uslovima ispita sposobnost polena linije kukuruza L217 da nakon čuvanja u uslovima +4 i -20°C, opraši drugu liniju kukuruza i da zrno. Majka je sejana u pet rokova setve, a polen oca je uziman dva puta, prosejavan i skladišten u frižider i zamrzivač zajedno sa silika gelom. Sukcesivno je oprašivano po pet klipova kukuruza. Izuzev očekivano dobro ozrnjenih klipova oprašenih svežim polenom, procenat oplođenih zrna, nakon samo jednog dana čuvanja u frižideru, je iznosio 4,4%, da bi četvrtog i petog dana čuvanja opao na 0,2% i 0,4%, respektivno. Biljke oprašene polenom čuvanim 20 dana nisu dale nijedno zrno. Polen čuvan u zamrzivaču je izgubio životnu sposobnost nakon samo jednog dana čuvanja. Ovako loši rezultati mogu biti posledica specifičnosti linije oca (poznato je da polen nekih linija kukuruza zadržava vijabilnost veoma kratko), ali i posledica propusta u manipulaciji polenom. Sa ciljem da se isprave primećeni propusti planirano je ponavljanje eksperimenta.

abstract = "In plant breeding programs, it is often necessary to cross genotypes incompatible in time of flowering. In maize, when the incompatibility in flowering period could not be overcome by different sowing dates, or by the ability of silk to preserve its fertility in 10-15 days, conservation of pollen could be of great importance. For many plant species, the appropriate methods for pollen management have been set up, including methods of collecting, desiccation, testing of viability and longevity, as well as for pollen storage. The longevity of pollen during its storage depends upon plant species, conditions at the time of pollen collecting, pollen moisture content, as well as upon storage temperature and duration. Even within the same plant species, different genotypes exhibit different level of viability preservation during the conservation. Although maize pollen belongs to a tricellular pollen group and rapidly loses viability under field conditions, its preservation is possible. According to the literature, pollen viability could be preserved for 30 days in the conditions of refrigerator (+4°C), while in liquid nitrogen (-196°C) up to 120 days. In the majority of studies, pollen viability was evaluated in the laboratory conditions, and the results obtained could largely be differed from those obtained under field conditions, due to impossibility to control a number of environmental factors. This experiment was conducted under field conditions in order to evaluate the ability of pollen from commercial maize inbred line L217, stored under the conditions of +4°C and -20°C, to pollinate maize inbred L73B013 and produce grain. Inbred L73B013 is sown in five sowing dates in order to ensure the longer presence of fresh silk. Pollen samples from line L217 were taken twice, and along with silica gel, stored in refrigerator and freezer. Each of successive pollination included five silks. Except for the expected good ear seed set when silks were pollinated with fresh pollen, the next successive pollination resulted in extremely poor ear seed set. Pollen stored in the freezer for one day completely lost vitality, while the pollination with pollen stored for three days resulted in one kernel per ear (for two ears). Pollination with pollen stored for four days resulted in one kernel per ear for only one ear. Pollen stored at + 4°C gave slightly better, but still very poor results. Compared to control, the percentage of seed set for pollen stored only for one day was 4.4%, being decreased to 0.2% and 0.4% for pollen stored for four and five days, respectively. Plants pollinated with pollen stored for 20 days did not give any grain. Such poor results may be a consequence of species specific properties of inbred L217, but also a consequence of failure in the manipulation of pollen. A highly sensitive point during the storage of pollen, especially in species with pollen sensitive to dehydration, such as the maize pollen, is the process of drying before its storing. Therefore, we concluded that the procedure of pollen desiccation probably was not adequate. With the aim of correcting the deficiencies observed, the experiment will be repeated in 2017., U programima oplemenjivanja kukuruza, u slučaju kada se nekompatibilnost u vremenu cvetanja oca i majke ne može prevazići setvom roditelja u različitim rokovima ili sposobnošću svile da očuva plodnost 10-15 dana, čuvanje polena bi moglo da ima značaja. Cilj izloženih istraživanja je bio da se u poljskim uslovima ispita sposobnost polena linije kukuruza L217 da nakon čuvanja u uslovima +4 i -20°C, opraši drugu liniju kukuruza i da zrno. Majka je sejana u pet rokova setve, a polen oca je uziman dva puta, prosejavan i skladišten u frižider i zamrzivač zajedno sa silika gelom. Sukcesivno je oprašivano po pet klipova kukuruza. Izuzev očekivano dobro ozrnjenih klipova oprašenih svežim polenom, procenat oplođenih zrna, nakon samo jednog dana čuvanja u frižideru, je iznosio 4,4%, da bi četvrtog i petog dana čuvanja opao na 0,2% i 0,4%, respektivno. Biljke oprašene polenom čuvanim 20 dana nisu dale nijedno zrno. Polen čuvan u zamrzivaču je izgubio životnu sposobnost nakon samo jednog dana čuvanja. Ovako loši rezultati mogu biti posledica specifičnosti linije oca (poznato je da polen nekih linija kukuruza zadržava vijabilnost veoma kratko), ali i posledica propusta u manipulaciji polenom. Sa ciljem da se isprave primećeni propusti planirano je ponavljanje eksperimenta.",

Conservation of maize germplasm provides the main resources for increased food and feed production. Conservation in gene banks (ex-situ) is dominant strategy for maize conservation. More than 130 000 maize accessions, e.g. about 40% of total number, are stored in ten largest gene banks worldwide and Maize Research Institute Zemun Polje (MRIZP) gene bank, with about 6000 accessions, is among them. Organized collecting missions started in 1961. in the former Yugoslavian territory, and up today, more than 2000 local maize landraces were stored. Pre-breeding activities that refer to identification of desirable traits from unadapted germplasm within genebank, result in materials expected to be included in breeding programs. Successful examples are LAMP, GEM and GENRES projects. At the end of XX century, at MRIZP genebank two pre-breeding activities were undertaken: eco-core and elite-core collections were created and landraces fulfilled particular criteria were chosen. In the last decade, MRIZP genebank collection was used for identification of sources for drought tolerance and improved grain quality. According to agronomic traits and general combining ability, two mini-core collections were created and included in commercial breeding programs.

AB  - Maintenance of the original accessions identity and integrity is one of the priorities among genebank activities. Different factors related to conservation may result in accessions disruption. Regeneration is the most frequent critical point in this process, due to bottlenecks, inbreeding, random genetic drift and unintentional mixing or contamination. On the other hand, genetic drift may occur due to seed viability loss. Therefore, it is very important to establish the balance between the frequency of regeneration and the duration of accession conservation. The aim of the present study was to estimate whether the identity of accessions regenerated after 27 years of medium-term conservation was disrupted. Phenotypic markers were applied on three Maize Research Institute "Zemun Polje" (MRIZP) genebank maize landraces (K2026, K768 and K86), differing in seed viability, kernel type and effective population size. It was estimated that, after the regeneration, there had been no significant changes in the landrace K2026. There were some parameters indicating that genetic drift had occurred in the landrace K768, and that there had been even a certain degree of inbreeding in the landrace K86. According to the results, accession K2026 could still be kept under the same ID number. Due to the genuine identity disruption, assignment of new ID numbers for K768 and K86 should be suggested.

The following traits were analyzed: grain yield (t/ha), kernel size, 1000 kernel weight, popping volume, percentage of unpopped kernels, and sensory characteristics (the appearance, taste, smell, tenderness, crispness, adhesiveness to the teeth, presence of pericarp and overall taste acceptability of popcorns). The analysis of variance showed significant differences between the popcorn hybrids with regard to the traits analyzed. The grain yield ranged from 4.78 t/ha (ZP 644/1k) to 7.38 t/ha (ZP 557/1k). The lowest popping volume was noticed in ZP 501k (28 cm3/g), whereas the highest popping volume was found in the lower-yielding hybrid ZP 544/1k (40.17 cm3/g). The percentage of unpopped kernels was very low and it ranged from 0.66% to 4.57%. The analysis of sensory characteristics of popcorns also showed differences between 12 popcorn hybrids.

AB  - BACKGROUNDBee pollen has already proved to be a good supplement rich in iron and zinc. Studies on the application of flower pollen in the food industry and medicine have begun. Bearing in mind the prevalence of maize as a crop culture, its pollen will be easily available. The mineral composition of pollen of seven Serbian maize hybrids was analyzed in order to establish its nutritional value and the benefits of its implementation in the human diet using the inductively coupled plasma method. RESULTSThe presence of twenty four different macro- (nine) and micronutrients (fifteen) was detected. The most common minerals were phosphorus and potassium, while arsenic, cobalt, lead, nickel and molybdenum were found in some samples. CONCLUSIONComparing the results obtained with recommended or tolerable dietary intake references for adults, it was found that maize pollen can be used as a very good source of zinc, iron, chromium and manganese for humans. With regard to selenium content, pollen samples proved to be moderately good source of this important micronutrient. Contents of some elements (Fe, Zn, Mn, Cr, Se, Al and V) showed significant differences depending on hybrid type. In some samples increased concentrations of aluminum and vanadium were recorded, which may pose a potential problem due to their toxicity. (c) 2016 Society of Chemical Industry

abstract = "BACKGROUNDBee pollen has already proved to be a good supplement rich in iron and zinc. Studies on the application of flower pollen in the food industry and medicine have begun. Bearing in mind the prevalence of maize as a crop culture, its pollen will be easily available. The mineral composition of pollen of seven Serbian maize hybrids was analyzed in order to establish its nutritional value and the benefits of its implementation in the human diet using the inductively coupled plasma method. RESULTSThe presence of twenty four different macro- (nine) and micronutrients (fifteen) was detected. The most common minerals were phosphorus and potassium, while arsenic, cobalt, lead, nickel and molybdenum were found in some samples. CONCLUSIONComparing the results obtained with recommended or tolerable dietary intake references for adults, it was found that maize pollen can be used as a very good source of zinc, iron, chromium and manganese for humans. With regard to selenium content, pollen samples proved to be moderately good source of this important micronutrient. Contents of some elements (Fe, Zn, Mn, Cr, Se, Al and V) showed significant differences depending on hybrid type. In some samples increased concentrations of aluminum and vanadium were recorded, which may pose a potential problem due to their toxicity. (c) 2016 Society of Chemical Industry",

AB  - Serbia is a country with favourable agro-ecological conditions for agricultural production, especially for maize, sunflower, soybean, sugar beet and small grain cereals. Also, the tradition of successful seed production and plant breeding, include Serbia in countries with significant potential for the seed industry. Significant areas are used for seed production, and in 2014. for wheat, maize, soybean and sunflower this amounted: 19.003 ha, 10.487 ha, 8.116 ha and 1.590 ha, respectively. The events during the 1990s, international sanctions and civil war, depleted the national seed industry concerning material resources and the status. Transitional events that followed brought a series of changes in all activities including ownership, technology, commerce and the market. Currently, in addition to several state-own Institutes, a large number of international and national private seed companies compete on the Serbian market. Despite many stated negative trends for national seed industry, Serbia is still one of the major seed producers in Europe. Also, Serbia is still one of the countries whose results in plant breeding are competitive with the world's leading companies. With certain improvements Serbia can become an even better place for the seed industry. At the same time, we must not ignore the role of the public sector in the conservation of natural and technological resources, as well as development in plant breeding and seed sciences of our country.

Danas se, pored nekoliko državnih instituta, na tržištu Srbije nalazi veliki broj inostranih i domaćih privatnih semenskih kompanija. Ali i pored svih negativnih trendova na nacionalnu semensku industriju, ne mogu se prenebregnuti dve važne činjenice: 1. još uvek smo jedan od nekoliko vodećih evropskih proizvođača žitarica, ali i drugih biljnih vrsta; 2. još uvek smo jedna od retkih evropskih država čiji su rezultati u oplemenjivanju biljaka konkurentni vodećim svetskim kompanijama. Uz određena unapređenja na kojima se intenzivno radi, a odnose se na usklađivanje zakonske regulative sa EU kao i modernizacije postojećih doradnih kapaciteta, Srbija može postati još bolje mesto za semensku industriju.

AB  - Maize grains contain high level of carotenoids and tocopherols compared with other cereals. Among carotenoids the β-carotene has the highest activity and is considered important in breeding programs of biofortified crops. Changes in carotenoids content in the maize grain could be influence of genotype x environment interaction, or effect of existing relationship between the color of the endosperm and the presence of carotenoids. This research was performed to estimate differences in morphological traits, grain content of tocopherols (α-, β+γ-, δ-), β-carotene, lutein and zeaxantin in local and introduced populations from Maize Research Institute 'Zemun Polje' gene bank. Micronutrient content was detected by using high-performance liquid chromatography (HPLC). Coefficient of variation for morphological traits was less than 10%, except for grain yield per plant which vary about 18,6%. α-tocopherol content was in the range from 1.04-8.42 μgg-1 DW, and β-carotene content varied from 0.26 to 7.95 μgg-1 DW. δ-tocopherol was in significant correlation with number of kernels per row (r=0.700***), and β+γ-tocopherol was in significant negative correlation with plant and ear height (r=-0.601***; r=-0.591**). Correlations between morphological traits and α-tocopherol were weak and without significance. Kernel color was significantly correlated with the content of zeaxantin (r=0,590***) and β-carotene (r=0,398*). For biofortification purposes a pool of 11 landraces with increased content of both, β-carotene and α-tocopherol, will be created based on obtained results.
AB  - U odnosu na druge žitarice, zrno kukuruza sadrži visok nivo karotenoida i tokoferola. Od svih karotenoida β-karoten ima najveću aktivnost i smatra se najznačajnim u biofortifikacijskim programima oplemenjivanja žitarica. Ovo istraživanje je imalo za cilj da utvrdi razlike u morfološkim svojstvima, sadržaju tokoferola (α-, β+γ-, δ-), β-karotena, luteina i zeaksantina kod lokalnih i introdukovanih populacija kukuruza iz banke gena Instituta za kukuruz 'ZemunPolje'. Sadržaj mikronutrienata je utvrđen primenom HPLC metode. Koeficijent varijacije za morfološka svojstva je bio manji od 10%, osim za prinos zrna po biljci (Cv=18,6%). Sadržaj α-tokoferola je bio u rasponu od 1,04-8,42 μg g-1 suve mase, a β-karotena od 0,26 to 7,95 μg g-1suve mase. δ-tokoferol je bio u značajnoj korelaciji sa brojem zrna u redu (r=0,700***), dok je β+γ-tokoferol bio u značajnoj negativnoj korelaciji sa visinom biljke i klipa(r=-0,601***; r=- 0,591**). Korelacije između morfoloških svojstava i α-tokoferola bile su slabe i nesignifikantne. Boja zrna je bila u značajnoj korelaciji sa sadržajem zeaksantina (r=0,590***) i β-karotena (r=0,398*). Za potrebe biofortifikacije 'pool' od 11 populacija sa povećanim sadržajem i β-karotena i α-tokoferola biće formiran na osnovu dobijenih rezultata.

AB  - In maize (Zen mays L.) breeding programs, it is very important to define a genetic distance of inbred lines and to establish criteria and biometric methods for the satisfactory germplasm classification. A total of 29 inbred lines from Maize Research Institute "Zemun Polje" (MRIZP) breeding program, Belgrade, Serbia, were used to compare similarities obtained by morphological (according to UPOV- Union Internationale pour la Protection des Obtentions Vegetales) and molecular (simple sequence repeats, SSR) markers. The aim was to assess discriminative power of applied markers in the separation of related lines, and to determine the possibility of their application in choosing parental lines for breeding programs. Application of different marker types resulted in adequate separation of inbreds into divergent groups, which facilitates the choice of parental lines. However, there were still many inconsistencies between the field and laboratory results. The quality of information from morphological markers was improved by the application of the appropriate descriptor, measurement scale and the biometric method. According to the correspondence analysis, increased number of SSR markers will enable more reliable results. Regression analysis of morphological visual assessment (MVG) and SSR similarity of individual inbreds pointed out that in some cases morphological, and in others molecular markers more accurately reflected known pedigree information of tested maize lines. In the early generations of maize inbred lines testing, we propose utilization of information resulting from in orphologi cal markers, according to UPOV descriptor. However, application of adequate number of molecular (SSR) markers has an economic justification on a smaller number of elite lines in the later generations of line testing.

AB  - Predictions of global warming point out that frequency and severity of temperature and rainfall extremes are expected to increase in the following decades. Yield stability could be achieved by improvement in future breeding based on information of cereal reproduction under changed environmental conditions. Landraces are valuable sources of beneficial alleles, e.g. tolerance to drought and improved grain yield, for introgression into adapted germplasm. Twenty-six drought tolerant maize landraces, selected among gene bank accessions and previously tested under controlled drought conditions and in temperate climate, were evaluated, at two sites and two plant densities in Zemun Polje. Since 2014 was with enormous rainfalls and flooding, morphological and agronomical traits were measured. Obtained data, together with the results from dry 2012, were plotted for principal component analysis. One local landrace and two introduced landraces, medium in maturity, were selected according to PC analysis and achieved grain yield that was stable across different climatic conditions.
AB  - Procenjuje se da će u narednim decenijama, usled globalnog zagrevanja, doći do učestalije pojave ekstremnih temperatura i padavina. Ostvarivanje stabilnih prinosa u budućim programima oplemenjivanja zavisiće od informacija o mogućnostima reprodukcije useva u promenjenim uslovima spoljašnje sredine. Populacije predstavljaju dragocen izvor poželjnih alela (npr. za tolerantnost prema suši i poboljšanje prinosa) za introgresiju u adaptiranu germplazmu. Dvadeset šest populacija kukuruza, tolerantnih na sušu, odabranih iz banke gena i prethodno testiranih u uslovima kontrolisanog stresa suše, kao i u umerenom klimatu, testirane su na dva lokaliteta i u dve različite gustine u Zemun Polju. U 2014. godini koju su obeležile velike količine padavina i poplave, merena su morfološka i agronomska svojstva. Dobijeni podaci, zajedno sa podacima iz sušne 2012. godine obrađeni su PCA metodom (analiza glavnih komponenti). Jedna lokalna i dve introdukované, srednjestasne populacije, odabrane su na osnovu PC analize i ostvarenog prinosa zrna, koji je bio stabilan bez većih variranja, u različitim uslovima spoljašnje sredine.

abstract = "Predictions of global warming point out that frequency and severity of temperature and rainfall extremes are expected to increase in the following decades. Yield stability could be achieved by improvement in future breeding based on information of cereal reproduction under changed environmental conditions. Landraces are valuable sources of beneficial alleles, e.g. tolerance to drought and improved grain yield, for introgression into adapted germplasm. Twenty-six drought tolerant maize landraces, selected among gene bank accessions and previously tested under controlled drought conditions and in temperate climate, were evaluated, at two sites and two plant densities in Zemun Polje. Since 2014 was with enormous rainfalls and flooding, morphological and agronomical traits were measured. Obtained data, together with the results from dry 2012, were plotted for principal component analysis. One local landrace and two introduced landraces, medium in maturity, were selected according to PC analysis and achieved grain yield that was stable across different climatic conditions., Procenjuje se da će u narednim decenijama, usled globalnog zagrevanja, doći do učestalije pojave ekstremnih temperatura i padavina. Ostvarivanje stabilnih prinosa u budućim programima oplemenjivanja zavisiće od informacija o mogućnostima reprodukcije useva u promenjenim uslovima spoljašnje sredine. Populacije predstavljaju dragocen izvor poželjnih alela (npr. za tolerantnost prema suši i poboljšanje prinosa) za introgresiju u adaptiranu germplazmu. Dvadeset šest populacija kukuruza, tolerantnih na sušu, odabranih iz banke gena i prethodno testiranih u uslovima kontrolisanog stresa suše, kao i u umerenom klimatu, testirane su na dva lokaliteta i u dve različite gustine u Zemun Polju. U 2014. godini koju su obeležile velike količine padavina i poplave, merena su morfološka i agronomska svojstva. Dobijeni podaci, zajedno sa podacima iz sušne 2012. godine obrađeni su PCA metodom (analiza glavnih komponenti). Jedna lokalna i dve introdukované, srednjestasne populacije, odabrane su na osnovu PC analize i ostvarenog prinosa zrna, koji je bio stabilan bez većih variranja, u različitim uslovima spoljašnje sredine.",

AB  - Malnutrition, as a global problem, is mainly caused by low level of mineral elements in staple food (deficient soil). Biofortification is based on selection of genotypes with enhanced concentration of mineral elements in grain, as well as decreased concentration of substances which interfere bioavailability of mineral elements in gut (like phytic acid), and increased content of substances that increase availability (such as beta-carotene). The experiment with 51 maize (Zea mays L.) inbred lines with different heterotic background was set up in order to evaluate chemical composition of grain and to determine the relations between phytic acid (PA), beta-carotene, and mineral elements: Mg, Fe, Mn, and Zn. The highest average phytate, beta-carotene, Fe, and Mn content was found in grain of inbreds from Lancaster heterotic group. The highest content of Mg was in grain of Independent source and Zn in grain of BSSS group. Increased level of Fe and Mn in Lancaster lines could be partially affected by higher PA content in grain, while increased beta-carotene content could improve Mn and Zn availability from grain of BSSS genotypes and Mg availability from Lancaster inbreds. It is important to underline that PA reduction is followed by Zn content increase in grain of Lancaster heterotic group, as well as that variations in Mg, Fe, and Mn contents are independent on PA status in inbreds from Independent source, indicating that the genotypes with higher Mg, Fe and Mn status from this group could serve as favorable source for improved Mg, Fe, and Mn absorption.

AB  - A collection of 2217 landraces from western Balkan (former Yugoslavia) is maintained at Maize Research Institute Zemun Polje gene bank. Nine flint and nine dent accessions from six agro-ecological groups (races), chosen on the basis of diverse pedigrees, were analyzed for genetic relatedness using phenotypic and simple sequence repeat (SSR) markers. One of the aims was to establish a reliable set of SSR markers for a rapid diversity analysis using polyacrilamide gels and ethidium bromide staining. In the principal component analysis (PCA) the first three principal components accounted for 80.86% of total variation and separated most of the flint from dent landraces. Ten SSR primers revealed a total of 56 and 63 alleles in flint and dent landraces, respectively, with low stuttering and good allele resolution on the gels. High average PIC value (0.822) also supports informativeness and utility of the markers used in this study. Higher genetic variation was observed among flint genotypes, as genetic distances between flint landraces covered a larger range of values (0.11-0.38) than between dent (0.22 - 0.33) genotypes. Both phenotypic and SSR analyses distinguished flint and dent landraces, but neither of them could abstract agro-ecological groups. The SSR method used gave clear, easy to read band patterns that could be used for reliable allele frequency determination. Genetic diversity revealed for both markers indicated that the landraces were highly adapted to specific environmental conditions and purposes and could be valuable sources of genetic variability.

AB  - According to regional reports on climate, more frequent and severe droughts and floods are already apparent. Modern maize breeding for different purposes (e.g. drought tolerance) emphasizes the importance for improved maize ability to withstand adverse environmental conditions. Genotypes with drought tolerance obtain high grain yield under optimal conditions and lower, but stable yield under dry environmental conditions. Field testing was conducted in 2014, on twenty-three maize inbred lines differing in drought tolerance. The inbreds were evaluated in respect to morphological traits (plant and ear height, total number of leaves, number of leaves above uppermost ear, ear leaf length and width), yield components and grain yield per plant. The experiment was set up according to RCB design with two replications. To simulate water stress, two plant densities were applied. According to Principal Component Analysis and cluster analysis, five inbred lines (T1, T2, T4, T8 i T15) performed the highest stability in both experimental conditions. Those inbreds could be used as a source for drought tolerance in breeding programs.

AB  - Global warming and predictions of climatic changes additionally put breeding for drought tolerance in the focus of breeding programmes for maize. Extensive studies on the existing gene bank collection of the Maize Research Institute "Zemun Polje" have been performed with the aim to identify and form initial sources for the development of maize inbreds more tolerant to drought. All accessions (about 6,000) were exposed to controlled drought stress in Egypt. Out of this number, approximately 8% of the tested genotypes were selected. In this study attention was given to 321 selected Western Balkan maize landraces, adapted to temperate climate growing conditions and the day length. Data derived from morphological characterization according to CIMMYT/IBPGR descriptors for maize, along with the application of numerical classification methods, were used to define homogeneous landraces groups based on morphological similarities. Results obtained from hierarchical and non-hierarchical analyses revealed the formation of 11 divergent groups. According to the obtained grain yield and visually scored stalk lodging and stay green, approximately 15% of the accessions from each of 11 groups were selected. Further investigations are towards defining their heterotic patterns and their possible utilization in developing and improving synthetic populations.

AB  - Large number of accessions, usually stored in gene banks, makes the regeneration very expensive, involving at the same time risks to the genetic integrity of accessions. Therefore, monitoring viability of stored seeds is a very important operation in gene banks. In 2013, monitoring for seed viability was conducted on 703 local maize landraces from Maize Research Institute Zemun Polje (MRIZP) gene bank. According to the results of germination test under laboratory conditions on filter paper (BP, 20 double left right arrow 30 degrees C, ISTA Rules), 49 local landraces were chosen for additional germination testing in field and under laboratory conditions using sand as a growing media (S, 20 double left right arrow 30 degrees C, ISTA Rules). For testing in sand, extended period of germination monitoring (ISTA Rules, 5.6.4) was applied, while for evaluation of abnormal seedlings less strict criteria than those in ISTA Rules were used. Statistical analysis, showed that the determination of seed viability in the field (24th day) was in the best accordance with the results of germination testing in sand (counting on the 7th day). It was noticed that the extended evaluation in sand did not contribute to more precise results. Also, correlation analysis revealed the existence of a trend, indicating that higher germination rate was associated to higher level of kernel hardness.

AB  - In the process of plant breeding the application of relevant breeding criteria is very important. The Path analysis is broadly applied with the aim to define yield components that mostly determine the yield and that can be used as quality breeding criteria. However, the significance of revealed relationships between yield and yield components can be affected by various factors, such as diverse genetic material that is observed, traits included into analysis, environments in which the material is observed, as well as, the applied statistic approach to determine the nature of the relationships itself. The interrelationships of yield and yield components of 15 commercial maize hybrids were observed using the Path and factor analyses. According to results of Path analysis, plant height, ear diameter and grain moisture had highly significant genetic and phenotypic direct effects on grain yield. At the same time, factor analysis points out significant effects of two factors on grain yield. Factor 1 was mostly determined by ear length and number of kernels per row, while grain moisture content, ear and cob diameter mostly determined Factor 2.

AB  - Nine maize hybrids were grown with the aim to determine variations in chemical composition of the grain. Analyzed hybrids were grown in split-plot experimental design with tree replications in Sremska Mitrovica and Zemun Polje, during the summer of 2010 and 2011. Grain yield, protein, starch, oil, as well as, antioxidants like phytate, soluble phenolics and free sulfhydryl groups (PSH) were analyzed. Unfavorable meteorological conditions affected not only grain yield, but its chemical composition too, by decreasing starch, phenolics and PSH and increasing protein, oil and phytate concentrations. Hybrids from the FAO 600 maturity group achieved higher grain yield during unfavourable conditions, with higher starch and phytate contents and decreased levels of PSH and phenolics. Hybrids from the FAO 500 maturity group were much more stable in respect of protein and oil contents, irrespective to year and location. The grain yield did not have the same source of variations as the factors which determine nutritional quality, an exception being oil content, which decreased with the increase in the grain yield.
AB  - Devet hibrida kukuruza gajeno je sa ciljem utvrđivanja variranja u hemijskom sastavu zrna. Analizirani hibridi su gajeni prema split-plot eksperimentalnom dizajnu u tri ponavljanja u Sremskoj Mitrovici i Zemun Polju, tokom 2010. i 2011. godine. Analizirani su prinos zrna, sadržaj proteina, skroba, ulja i antioksidanata, kao što su fitat, rastvorljivi fenoli i slobodne sulfhidrilne grupe (PSH). Nepovoljni meteorološki uslovi su uticali na prinos kao i na promenu hemijskog sastava zrna, smanjujući sadržaj skroba, fenola i PSH i povećavajući koncentraciju proteina, ulja i fitata. Hibridi iz FAO grupe zrenja 600 su postigli veće prinose u nepovoljnim uslovima, sa povećanim nivoom skroba i fitata, kao i smanjenim nivoom PSH i fenola. Sadržaj proteina i ulja je bio znatno stabilniji kod hibrida iz FAO grupe 500,bez obzira na godinu i lokaciju. Prinos zrna nije imao isti izvor variranja, kao i faktori koji determinišu nutritivni kvalitet, izuzimajući ulja čiji se sadržaj smanjivao povećanjem prinosa.

AB  - A relatively narrow genetic background, limited sources of germplasm that satisfies commercial standards, poorly defined heterotic groups, as well as a small span for yield and quality estimation are reasons for the modest improvement in sweet corn yields in comparison with standard grain quality maize. Therefore, any additional information could be of a great use. Based on the phenotypic characterization according to UPOV descriptor, phenotypic distances of 14 ZP sweet corn inbred lines were evaluated, and clustering was performed. Grouping showed that 9 out of 11 hybrids obtained by crossings of 14 sweet corn inbred lines had parental lines assigned to different subclusters. Two hybrids whose parental components belonged to the same subcluster had some important specific traits, such as early maturity (ZP 111su), and super-sweet germplasm (ZP 407su). Results obtained by this procedure could be of great assistance in the process of selecting parental lines for the future crossings.
AB  - Relativno uska genetička osnova, ograničeni resursi germplazme koja zadovoljava komercijalne standarde, loše definisane heterotične grupe kao i kratko vreme koje je na raspolaganju za procenu prinosa i kvaliteta su razlozi slabijeg unapređenja prinosa hibrida kukuruza šećerca u poređenju sa hibridima standardnog kvaliteta zrna. Stoga svaka dodatna informacija može da bude od velikog značaja. Na osnovu karakterizacije po UPOV deskriptoru urađena je klaster analiza 14 ZP linija kukuruza šećerca. Grupisanje je ukazalo da su se roditeljske linije 9 od 11 hibrida grupisale u različite podklastere. Dva hibrida, čije su se roditeljske linije grupisale u isti klaster su nosioci nekih specifičnih karakteristika kao što je ranostasnost (ZP 111su) i super-slatka germplazma (ZP 407su). Rezultati grupisanja dobijeni ovom procedurom mogu biti od velike pomoći pri izboru roditeljskih linija za buduća ukrštanja linija šećerca.
