AB  - Although accompanied with adverse low temperatures, early maize sowing could be
used to avoid drought during flowering and diminish yield losses. Herein, a small-scale
experiment of low temperature stress (LTS) on maize lines L1 (tolerant), L2 (medium
tolerant) and L3 (susceptible) is presented. Plants were grown in pots exposed to
exterior suboptimal (March) and optimal (late April) temperatures until three leaf stage.
Chlorophyll (CH), flavonoids (FL), anthocyanins (AN) and nitrogen balance (NBI)
indices were measured using Dualex Scientific optical device. Growth parameters were
also determined. Under LTS, number of plants was unchanged for L1 and halved for L2
and L3. Compared to L2 and L3, L1 had significantly higher (p<0.05) shoot fresh
weight (0.649 g vs. 0.406 g and 0.303 g), AN (0.17 vs. 0.13) and FL (1.47 vs. 1.38 and
1.36). For recovery evaluation, plants were transplanted into the field. Transplanted
stressed L1 plants showed the highest grain yield per plant (55g) in the field. Due to
high correlations (p<0.01) between FL in three leaf stage and grain yield per plant, FL
could be used as an indicator of plant recovery of maize genotypes exposed to LTS
during early sowing.
AB  - Ranom setvom kukuruza se može izbeći efekat suše u fazi cvetanja i tako preduprediti smanjenje
prinosa uprkos nepovoljnim temperaturama u tom periodu. U ovom istraživanju prezentovani su
rezultati efekta niskih temperatura na tri linije kukuruza: L1 (tolerantna), L2 (srednje osetljiva) i
L3 (osetljiva). Biljke su gajene do faze trećeg lista u saksijama izloženim suboptimalnim (mart) i
optimalnim (april) spoljnim temperaturama. Sadržaj hlorofila, flavonoida i antocijana kao i
nitrogen balance index (NBI) su mereni korišćenjem uređaja Dualex Scientific (Force-A, Orsay,
France). Takođe, mereni su i parametri rasta. U poređenju sa L2 i L3, L1 je imao značajno veću
(p<0.05) svežu masu nadzemnog dela biljke (0.649 g vs. 0.406 g i 0.303 g), antocijana (0.17 vs.
0.13) i flavonoida (1.47 vs. 1.38 i 1.36). Biljke su presađene u polje radi procene oporavka.
Presađene biljke genotipa L1 su pokazale najveći prinos po biljci u polju (55g). S obzirom na
visoku korelaciju između sadržaja flavonoida u fazi trećeg lista i prinosa po biljci (p<0.01),

AB  - Nutritional  quality  of  maize  is  low  because  maize  protein  is  poor  in  several  essential amino  acids.  The  purpose  of  this  research  was  to  analyze  agronomic  traits  and  kernel biochemical and physical properties of 16 gene bank accessions which comprise a mini-core  collection  for  grain  quality  and  to  identify  populations  for  improving  protein quality.  Standard  ZP341  hybrid  was  superior  for  half  of  agronomic  traits  tested, especially  grain  yield,  which  was  higher  from  24%  to  six  times.  Ten  accessions  had protein  content  over  14  %  and  were  further  analyzed  for  amino  acid  composition  and kernel  characteristics.  Additionally,  genetic  relationships  between  the  accessions  were determined   by   Simple   Sequence   Repeats   (SSRs)   analysis   with   30   primers.   All accessions  showed  elevated  contents  of  most  essential  amino  acids.  Population  L492 with  1.87  and  0.68  g  100g-1dry  weight  had  the  highest  contents  of  leucine  and phenylalanine, respectively, but also higher contents of most other analyzed amino acids (p<0.05). Cluster analysis based on SSRs also distinguished L492 by separating it from all other accessions. Compared to ZP341, accessions were significantly inferior in grain weight  and  dimensions  (p<0.05),  but  superior  in  most  hardness  parameters  (p<0.05). Pearson  correlations  revealed  lack  of  negative  correlations  between  biochemical  traits, indicating  a  possibility  for  concurrent  improvement  of  several  amino  acids.  The  best way  of  improving  protein  quality  of  elite  materials  is  through  backcrossing  and  as populations  were  chosen  according  to  their  good  general  combining  ability  (with IoDent,  Lancaster  and  BSSS),  they  could  serve  for  improvement  of  elite  materials  of these genetic origins.

Hibrid ZP 341 (standard) je bio superioran za većinu testiranih agronomskih svojstava, sa prinosom zrna većim za 24% do 600%.

Svi  uzorci  su  pokazali  povećan  sadržaj  većine  esencijalnih  amino  kiselina. Populacija L492 je imala najveći sadržaj leucina (1.87g 100g-1suve  mase)  i  fenilalanina  (0.68g 100g-1suve  mase),  ali  i  veće  sadržaje  ostalih  aminokiselina  (p<0.05)  u  odnosu  na  ZP341  i analizirane  populacije.

AB  - Early maize sowing enables longer growing season with enhanced possibility of achieving higher and more stable yields, and better chances of avoiding summer droughts. For early sowing, cold-tolerant maize genotypes should be used. Breeding maize, tolerant to low temperatures, requires knowledge of genetic diversity and heterotic patterns of breeding material. The objective of this study was to determine genetic diversity of 15 ZP maize inbred lines applying the method of protein markers (UTLIEF method), and to establish correspondence between thus obtained classification with the results of cold test (CT) and field emergence (FE). During two production seasons (2011 and 2014), 15 maize inbred lines were self-pollinated. Pedigree data showed that material belongs to different maturity and heterotic groups. Cold tolerance was assessed in laboratory (2015) by cold test (7.5 degrees C, 10 days), and field trials on two locations during two successive years (2015, 2016). ZP maize inbred lines showed very good response to stressful conditions of CT and FE. Inbred lines with Lancaster background were more sensitive to low temperatures than inbred lines with BSSS and Iowa Dent background. Based on UTLIEF method two inbred lines with Lancaster background (ZPL 5 and ZPL 7) were grouped by cluster analysis together with Iowa Dent inbred lines, that also expressed better cold tolerance, and thus exceptional consent was achieved with the results of CT and FE. Classification of maize inbred lines based on UTLIEF method, followed by cluster analysis and PCA, showed good agreement with pedigree data, which points out that this method could be successfully applied for genetic classification of breeding material of a wide genetic background.

AB  - A total of seven maize inbred lines of different origin and maturity group were used in the trial set up according to the split-plot randomized complete block design in five environments. Each inbred was observed in five variants: original inbred (N); cytoplasmic male sterile C-type (CMS-C); restorer for CMS-C (RfC); cytoplasmic male sterile S-type (CMS-S) and restorer for CMS-S (RfS). The objective was to compare grain yield of original inbreds and their CMS and Rf variants and to apply Isoelectric focusing (IEF) to determine whether the conversion of original inbreds to their CMS and Rf counterparts have been done completely. Protein markers have shown that conversion of almost all inbreds was done good and completely. Only original inbreds ZPL2 and ZPL5 did not concur on banding patterns with their RfC variants. The type of cytoplasm had a very significant impact on grain yield. Namely, CMS-C counterparts significantly out yielded their CMS-S versions, while the inbreds with C and S cytoplasm over yielded inbreds with N cytoplasm, as well as their RfC and RfS versions.

abstract = "A total of seven maize inbred lines of different origin and maturity group were used in the trial set up according to the split-plot randomized complete block design in five environments. Each inbred was observed in five variants: original inbred (N); cytoplasmic male sterile C-type (CMS-C); restorer for CMS-C (RfC); cytoplasmic male sterile S-type (CMS-S) and restorer for CMS-S (RfS). The objective was to compare grain yield of original inbreds and their CMS and Rf variants and to apply Isoelectric focusing (IEF) to determine whether the conversion of original inbreds to their CMS and Rf counterparts have been done completely. Protein markers have shown that conversion of almost all inbreds was done good and completely. Only original inbreds ZPL2 and ZPL5 did not concur on banding patterns with their RfC variants. The type of cytoplasm had a very significant impact on grain yield. Namely, CMS-C counterparts significantly out yielded their CMS-S versions, while the inbreds with C and S cytoplasm over yielded inbreds with N cytoplasm, as well as their RfC and RfS versions.",

AB  - Mineral elements deficiency in food can cause serious health problems. Being one of the three most importatnt macroelements for plant nutrition, phosphorus is involved in several key processes: photosynthesis, respiration, synthesis of starch, transport of carbohydrates and products of photosynthesis, cell division and increased water utilization. The objective of this study was to estimate the dynamics of inorganic phosphorus (Pi), as a precursor in the synthesis of phytic acid, and phytic phosphorus (Pphy) accumulation during the grain filling of two maize inbred lines differing in FAO maturity groups - L217 and L773. In addition, possible linkage between phosphorus content in grain and agro-morphological performances was observed. For the analysis of the dynamics in Pi and Pphy contents, seed samples were taken at 15th, 30th, 45th and 60th day after the polination. The obtained results showed a continuous decline of Pi content in both genotypes, with the most intensive decline observed at the first interval (e.i. 15-30 days) after the polination. The trend observed was much more pronounced in L217. Moreover, this inbred acheaved higher grain yield for 61.8 % at first sowing and for 63.1 % at 10-day delayed sowing, respectively, compared to inbred L773. In all three intervals observed, the decrease of Pi content was highly correlated with Pphy content increase for both genotypes. Based on lower accumulation rate, followed by lower Pphy content (2.635 mg g-1) during the stage of physiological maturuty, it could be concluded that inbred L217 could be considered as potentialy suitable genotype for low-phytic hybride selection.
AB  - Nedostatak mineralnih elemenata u hrani, može izazvati ozbiljne zdravstvene probleme. Kao jedan od tri najvažnija makroelementa u ishrani biljaka, fosfor učestvuje u nizu procesa u biljci: fotosintezi, disanju, sintezi skroba, transportu ugljenih hidrata i produkata fotosinteze, deobi ćelija i boljem korišćenju vode. Ciljevi ovog istraživanja su uključivali praćenje dinamike nakupljanja neorganskog fosfora (Pi) - prekursora u sintezi fitinske kiseline, i fitinskog fosfora (Pphy), tokom nalivanja zrna dve samooplodne linije kukuruza različitih FAO grupa zrenja - L217 i L773, i utvrđivanje povezanosti sadržaja fosfora u zrnu i agro-morfoloških performansi. Za analizu dinamike sadržaja neorganskog i fitinskog fosfora, uzorci zrna su uzimani: 15-tog, 30- tog, 45-tog i 60-tog dana nakon oplodnje. Na osnovu dobijenih rezultata, uočen je kontinuirani pad sadržaja neorganskog fosfora kod oba genotipa, a najintezivniji pad utvrđen je u prvom intervalu (tj. 15-30 dana) nakon oplodnje, bivajući znatno izraženiji kod linije L217. Takođe, u odnosu na liniju L773, linija L217 je ostvarila viši prinos za 61,8 % u prvom, odnosno za 63,1 % u drugom setvenom roku, respektivno. Srazmerno smanjenju neorganskog fosfora, uočen je trend povećanja fitinskog fosfora kod oba genotipa tokom sva tri intervala merenja. Smanjena dinamika nakupljanja i niži sadržaj fitinskog fosfora (2,635 mg g-1) u fazi fiziološke zrelosti, ukazuje da bi se inbred linija L217 mogla smatrati potencijalno poželjnim genotipom za selekciju niskofitinskih hibrida.

AB  - Antioxidant systems of maize root cell walls grown on different nitrogen sources were evaluated. Plants were grown on a medium containing only NO3- or the mixture of NO3-+NH4+, in a 2:1 ratio. Eleven-day old plants, two days after the initiation of lateral roots, were used for the experiments. Cell walls were isolated from lateral roots and primary root segments, 2-7 cm from tip to base, representing zones of intense or decreased growth rates, respectively. Protein content and the activity of enzymes peroxidase, malate dehydrogenase and ascorbate oxidase ionically or covalently bound to the walls, as well as cell wall phenolic content and antioxidant capacity, were determined. Cell walls of plants grown on mixed N possess more developed enzymatic antioxidant systems and lower non-enzymatic antioxidant defenses than cell walls grown on NO3-. Irrespective of N treatment, the activities of all studied enzymes and protein content were higher in cell walls of lateral compared to primary roots. Phenolic content of cell walls isolated from lateral roots was higher in NO3--grown than in mixed N grown plants. No significant differences could be observed in the isozyme patterns of cell wall peroxidases isolated from plants grown on different nutrient solution. Our results indicate that different N treatments modify the antioxidant systems of root cell walls. Treatment with NO3- resulted in an increase of constitutive phenolic content, while the combination of NO3-+NH4+ elevated the redox enzyme activities in root cell walls.

AB  - High-quality seed is one of the key factors in the commercial maize grain production. In addition, hybrid seed production is conditioned by the production of basic seed of parental inbreds. According to the Law on Seed, 2005, the category of basic seed is defined as: original of self-pollinated plant species, hybrid components and potato elite, produced under control of the Ministry competent for agribusiness and is used for the production of certified seed of the first generation. This paper presents a chronological overview of the overall activity since1945. that led to the modern production of maize seed in our country. The activities have been based on scientific, technical and technological achievements within many fields, ranging from genetics and breeding, through growing practices, processing, quality control and legal regulations concerning all of this. Transition from maize breeding and production to hybrids has provided an amazing development of maize breeding and seed production and also included significant profit. Therefore, maize seed production has become high-technology industry. The scientific and professional work in improving the production of basic seed of ZP maize hybrids has been carried out in stages, and generally followed achievements in maize breeding and genetics, as well as developments in the growing practices and processing. In order to maintain a high quality of maize hybrid seed, as the end product, permanent efforts have to be invested into maize production improvement, drying, processing, storing, genetic purity of basic seed of parental inbreds of ZP maize hybrids, which are grown on the significant percentage of maize production areas not only in Serbia and countries in the region.

AB  - Six inbred lines were crossed according to incomplete diallel method. In this way fifteen hybrid combinations were obtained. Hybrid combinations derived from these parental components were used in this work. The objective of study was to estimate direct and indirect effects of five morphological traits on grain yield by the application of the simple coefficient correlation and path coefficient analysis. The trait number of leaves above the top ear with the value of 0.736 has the strongest direct positive effect on grain yield. Positive direct effects on grain yield were also observed for height to tassel base and plant height, while negative direct effects were observed for ear height and total number of leaves. As far as indirect effects were considered, a positive effect of the ear position height on yield over the total plant height stands out. The evaluation of the proportion of mutual effects of five observed morphological traits on grain yield, expressed by the coefficient of multiple determination (R-y12345(2)) amounted to 0.7881.

AB  - Comparative biochemical characterization of class III peroxidase activity tightly bound to the cell walls of maize roots was performed. Ionically bound proteins were solubilized from isolated walls by salt washing, and the remaining covalently bound peroxidases were released, either by enzymatic digestion or by a novel alkaline extraction procedure that released covalently bound alkali-resistant peroxidase enzyme. Solubilized fractions, as well as the salt-washed cell wall fragments containing covalently bound proteins, were analyzed for peroxidase activity. Peroxidative and oxidative activities indicated that peroxidase enzymes were predominately associated with walls by ionic interactions, and this fraction differs from the covalently bound one according to molecular weight, isozyme patterns, and biochemical parameters. The effect of covalent binding was evaluated by comparison of the catalytic properties of the enzyme bound to the salt-washed cell wall fragments with the corresponding solubilized and released enzyme. Higher thermal stability, improved resistance to KCN, increased susceptibility to H2O2, stimulated capacity of wall-bound enzyme to oxidize indole-3-acetic acid (IAA) as well as the difference in kinetic parameters between free and bound enzymes point to conformational changes due to covalent binding. Differences in biochemical properties of ionically and covalently bound peroxidases, as well as the modulation of the enzyme properties as a result of covalent binding to the walls, indicate that these two fractions of apoplastic peroxidases play different roles.

AB  - An analysis of peroxidase and ascorbate oxidase activity, phenolic content and antioxidant capacity of isolated maize root cell walls was performed in controls and plants stressed with polyethylene glycol (PEG) or heavy metals, zinc or copper. Peroxidase activity (oxidative and peroxidative) was more pronounced in the ionic than in the covalent cell wall fraction. PEG induced an increase and Zn2+ a decrease of both ionically bound peroxidase activities. In the covalent fraction, Cu2+ decreased oxidative and increased peroxidative activity of peroxidase. Isoelectric focusing of ionically bound proteins and activity staining for peroxidase demonstrated increased intensities and appearance of new acidic isoforms, especially in Zn2+ and PEG treatments. Most pronounced basic isoforms (pI similar to 7.5) in controls, decreased in intensity or completely disappeared in stressed plants. Ascorbate oxidase activity was significantly increased by PEG and decreased by Zn2+ treatments, and highly correlated with peroxidase activity. Antioxidant capacity and total phenolics content increased in heavy metal-treated and decreased in PEG-treated plants. Analysis of individual phenolic components revealed p-coumaric and ferulic acids, as the most abundant, as well as ferulic acid dimers, trimers and tetramers in the cell walls; their quantity increased under stress conditions. Results presented demonstrate the existence of diverse mechanisms of plant response to different stresses.

AB  - In gene-bank maize collection of Maize Research Institute Zemun Polje (MRI) two samples with untypical mtDNA profile for cytoplasmic male sterility (cms) were identified. These two samples showed typical multiplex polymerase chain reaction (PCR) band for cms-S, but also an additional band of unknown nature. It is assumed that the additional band is the result of a rearrangement of the two mitochondrial episomes characteristic for the cms-S in maize or a duplication of the part of cms-S mitochondrial genome.

AB  - A collection of 2217 landraces from former Yugoslavia region is maintained at Maize Research Institute Zemun Polje gene bank. All local varieties from the former Yugoslavia are classified into 18 groups. These agroecological groups encompass early introduced flint types grown on small and isolated areas, later introduced dent types that spread on wide areas of crop production and types created through hybridization between these two kernel types. The objective of this research was to study population structure, genetic diversity and relationships of nine flint and nine dent accessions belonging to different agro-ecological groups using phenotypic and simple sequence repeat (SSR) markers. The 18 analyzed landraces displayed great variation for most analyzed traits, but flint landraces were more diverse. Ten SSR probes revealed total of 56 and 62 alleles in flint and dent landraces, respectively. Eight specific alleles (i.e. alleles found only in one landrace or only within flint, i.e. dent landraces) were detected with five probes. One specific allele was found in flint and seven alleles in dent landraces. These differences in allele structure point to different origins and possibly different purposes of flint and dent genotypes. Both phenotypic and SSR analyses could distinguish most flint and dent landraces, but not agro-ecological groups. The results revealed a significant genetic heterogeneity indicating that the analyzed landraces could be valuable sources of genetic variability.

Cilj ovog rada je bio da se utvrdi struktura i genetička divergentnost, pomoću fenotipskih i SSR markera, devet populacija tvrdunaca i devet populacija zubana koji pripadaju različitim agro-ekološkim grupama. Analizirane populacije su pokazale visok stepen varijacija za većinu analiziranih osobina, mada su populacije tvrdunaca bile raznovrsnije.

AB  - Quality protein maize (QPM) is high lysine (tryptophan) maize with hard endosperm and good agronomic performance. QPM was developed primarily for utilization in tropical and sub-tropical regions where maize is a staple food. Its adaptation and cultivation in temperate areas is still not fully developed, although QPM could have merits for production and consumption in developed parts of the world, especially as animal feed. Maize Research Institute Zemun Polje has a program on developing QPM genotypes for growing in temperate regions. The objective of our research was initial screening of 72 hybrids (derived from crosses between QPM lines adapted to temperate environments and three commercial lines with standard kernel quality) for kernel modification, tryptophan and protein contents, quality index (QI) and grain yield. Five hybrids with high tryptophan content (0.071 to 0.081%) and yield at the level of standard hybrids (96 - 114%) were identified. Protein content ranged from 10 to 11.20%, similar to standard hybrids. QI was in the range from 0.71 to 0.74, which was better than in standard hybrids (0.57 - 0.62), but below the QPM threshold of 0.80. The percentage of good kernel modifications (type 1 and 2) was over 80% in three and over 74% in two hybrids. The results indicated the complexity of obtaining high yielding hybrids with high levels of essential amino-acids. Identified potential QPM hybrids have to be further evaluated for agronomic traits, but the results can be considered important in the context of limited information on QPM adapted to temperate environmental conditions.

AB  - The influence of osmotic stress induced by polyethylene glycol (PEG) on plant growth, proline content and activities of soluble peroxidases was studied on 12 maize inbred lines at seedling stage. Reduction of plant growth, fresh weight and length of roots and shoots occurred in all of the studied genotypes and was followed by increase in free proline content of shoots and especially in roots of the majority of genotypes. Correlation analysis of changes in root proline content with growth parameters revealed direct positive correlation. Changes in root peroxidase activities ranged from approximately 40 % reduction to 20 % stimulation, depending on the genotype. It was shown that genotypes with higher proline changes under drought treatment exhibited lower peroxidase activities. In addition, genotypes with less pronounced root growth reduction under stress conditions exhibited increased peroxidase activities, as well as lower proline content. In the field experiments, grain yield was positively correlated with root proline content and negatively with root length changes in drought-treated seedlings grown in laboratory conditions.

AB  - Due to the low biological value of proteins of common maize, it was reinitiated breeding for high protein quality maize (HQPM) using three genetic systems, namely: opaque-2 gene, endosperm modifier genes and enhancer genes, which are increasing lysine and tryptophan content in opaque-2 background In order to alleviate effect of abiotic and biotic stress factors, the genotypes with tolerance to those factors were included. Genetic resources originating from North, Central and South America, then West, Central and Southern Africa and gene bank of Maize Research Institute 'Zemun Polje' were used.

AB  - Cytoplasmic male sterility (cms) in maize is used to increase the quality of hybrid seed production and reduce its costs. Sterile hybrids often outyield their fertile counterparts, especially if pollinated by a genetically unrelated pollinator. This fact can be used in modern production to increase grain yield of maize hybrids, and to improve agronomic traits. The combined effect of cytoplasmic male sterility and xenia (the influence of pollinators in the year of pollination) is called the Plus-hybrid effect. Accordingly, Plus-hybrid system refers to commercial production of two hybrids in the mixture, one of which is male sterile and high yielding, and other is unrelated fertile hybrid pollinator. Potential Plus-hybrid mixture consists of 75-80% of sterile hybrid and 20-25% of fertile hybrid. In modern agriculture continuously is searched for increased both grain yield and quality of cultivated hybrids. Plus-hybrid system represents one of these attempts. Investigations on Plus-hybrid effect in the world began in the late 20th century through a series of micro-trials and larger strip-trials in several locations and countries. The best Plus-hybrid combinations had significantly higher grain yield, without compromising quality, than the individual hybrids. The greater the genetic distance between the hybrids combined in the mixture, the expected Plus-hybrid effect is higher (due to the increased effect of xenia). Research conducted in Serbia was done at one location in three years and included two sterile hybrids as mothers and five fertile hybrids as fathers. It turned out that the Plus-hybrid effect had different influence on the investigated traits of the two hybrids, and this effect highly depends on the genotype of the mother. The increase in yield was accompanied with the increase in oil content in one of the sterile hybrids. In addition, health condition of the grain was not affected. It turned out that characteristics of fathers may influence the characteristics of pollinated mothers due to the xenia effects, so the choice of superior fathers increases the profits of the Plus-hybrid effect, also it seems that xenia effects with the same pollinator differ in sterile and fertile version of the same hybrid, and this phenomenon should be further investigated (it could be a kind of interaction between the sterile cytoplasm and xenia, that is different from the Plus-hybrid effect). What is significant is that the Plus-hybrid system can be successfully used to prevent pollination of genetically modified plants (GMO), growing the genetically modified cms maize hybrids mixed with unmodified fertile pollinators. The objective of this study was to determinate both, individual and combined (Plus-hybrid) effects, of cms and xenia on grain yield, chemical composition and grain health condition of examined hybrids. Although studies related to the Plus-hybrid system are very new, we believe that this unconventional approach of maize growing could enter the commercial use, which could be the most important significance of this research. The seed production of Plus-hybrid mixture is not more expensive than production of conventional hybrids, and this fact should increase its commercial use. Therefore, we would like to present results achieved so far and introduce a Plus-hybrid system of maize production.

AB  - Maize nutritional value is very poor due to deficiency of two essential amino acids - tryptophan and lysine. It was shown than opaque2 (o2) mutations increased lysine by 69-100% and tryptophan by 66% in the endosperm. The incorporation of opaque2 into high yielding commercial cultivars failed, because of its numerous agronomic and processing problems, caused by endosperm softness. These drawbacks have been corrected in genetically improved, hard endosperm quality protein maize (QPM) - a genotype in which opaque2 has been incorporated along with associated modifiers. The breeding project at the Maize Research Institute, Zemun Polje, involves QPM x opaque2, opaque2 x QPM and standard lines x QPM crosses, with the aim to improve MRI opaque2 or convert standard lines into QPM germplasm. F5 i BC1F3 plants of these crosses were phenotyped, yield per plant was determined and endosperm modification assessment and kernel biochemical analysis (protein content, tryptophan content and quality index) were performed, with the aim to select plants for further selection process. Opaque2 x QPM progenies had the highest yield per plant - 314.3 g in BC1F3 and 230.2 g in F5. The tryptophan content and the quality index in the whole grain of QPM and opaque2 progenies were at the levels set for QPM germplasm in 72% analysed genotypes, as well as, in seven out of nine genotypes of standard lines x QPM crosses.

abstract = "Maize nutritional value is very poor due to deficiency of two essential amino acids - tryptophan and lysine. It was shown than opaque2 (o2) mutations increased lysine by 69-100% and tryptophan by 66% in the endosperm. The incorporation of opaque2 into high yielding commercial cultivars failed, because of its numerous agronomic and processing problems, caused by endosperm softness. These drawbacks have been corrected in genetically improved, hard endosperm quality protein maize (QPM) - a genotype in which opaque2 has been incorporated along with associated modifiers. The breeding project at the Maize Research Institute, Zemun Polje, involves QPM x opaque2, opaque2 x QPM and standard lines x QPM crosses, with the aim to improve MRI opaque2 or convert standard lines into QPM germplasm. F5 i BC1F3 plants of these crosses were phenotyped, yield per plant was determined and endosperm modification assessment and kernel biochemical analysis (protein content, tryptophan content and quality index) were performed, with the aim to select plants for further selection process. Opaque2 x QPM progenies had the highest yield per plant - 314.3 g in BC1F3 and 230.2 g in F5. The tryptophan content and the quality index in the whole grain of QPM and opaque2 progenies were at the levels set for QPM germplasm in 72% analysed genotypes, as well as, in seven out of nine genotypes of standard lines x QPM crosses. All genotypes that had poorly modified kernels, the low tryptophan content and/or the low yield per plant will be discarded from further breeding., Hranjiva vrednost kukuruza je dosta niska zbog nedostatka dve esencijalne aminokiseline - lizina i triptofana.

AB  - Isolated cell walls from maize (Zea mays L) roots exhibited ionically and covalently bound NAD-specific malate dehydrogenase activity. The enzyme catalyses a rapid reduction of oxaloacetate and much slower oxidation of malate. The kinetic and regulatory properties of the cell wall enzyme solubilized with 1 M NaCl were different from those published for soluble, mitochondrial or plasma membrane malate dehydrogenase with respect to their ATP, Pi, and pH dependence. Isoelectric focusing of ionically-bound proteins and specific staining for malate dehydrogenase revealed characteristic isoforms present in cell wall isolate, different from those present in plasma membranes and crude homogenate. Much greater activity of cell wall-associated malate dehydrogenase was detected in the intensively growing lateral roots compared to primary root with decreased growth rates. Presence of Zn2+ and Cu2+ in the assay medium inhibited the activity of the wall-associated malate dehydrogenase. Exposure of maize plants to excess concentrations of Zn2+ and Cu2+ in the hydroponic solution inhibited lateral root growth, decreased malate dehydrogenase activity and changed isoform profiles. The results presented show that cell wall malate dehydrogenase is truly a wall-bound enzyme, and not an artefact of cytoplasmic contamination, involved in the developmental processes, and detoxification of heavy metals.

AB  - Choice of adequate sources of new favorable alleles to be included in elite maize (Zea mays L.) hybrids improvement programs is of the main interest for maize breeders. The objectives of this study were: to evaluate potential of seven maize populations as donors of new favorable alleles to improve the hybrid B73 x Mo17 for grain yield, ear length, number of rows, and weight of 1000 kernels, using 5 methods; to compare results obtained by the calculation of rank corellation coefficient (rs) after Spearman, as well as Kendall's coefficient of concordance (W) (Falconer, 1989). All evaluated maize populations had positive values of 1 (P) over bar (1)mu statistics proposed by Dudley (1987) for all traits. It confirms that broad based sources as favorable allele carriers could be useful in elite hybrid parents improvement. High level of agreement between three applied methods for maize populations evaluation as sources of favorable alleles were obtained for all investigated traits. The strongest corellation relationship between method proposed by Dudley (1987) and (X) over bar TC were calculated for number of rows (rs = 1**) and ear length (rs = 0.964**).

AB  - Standard induction processes of delayed fluorescence (DF) of chlorophyll (induction signals) occur when an intact leaf segment of maize inbreds and hybrids is kept in the phosphoroscope darkroom for more than 15 minutes (t > 15 min), and at the same time the leaf is illuminated with the intermittent white light. Resolved induction processes of DF chlorophyll into transients: A, B, C, D and E occur when the intact leaf segment of maize inbreds and hybrids is kept in the phosphoroscope darkroom for a significantly shorter period (500 s > t > 30 s), with the time rate t of 30 s, prior to its illumination with the intermittent white light. Induction transients: A, B, C, D and E are characterized with the time of their generation: tA = 31±6 ms (A), tB = 5 ± 0,5 s (B), tC = 15±5 s (C), tD = 360±20 s (D) and tE = 670±35 s (E), dynamics of changes in transients intensities (IA, IB, IC, ID and IE) and mechanisms of their generation. The induction processes of chlorophyll DF of the intact leaf of maize inbreds and hybrids resolved into transients: A, B, C, D and E are accompanied by the occurrence and different levels of activation energy (Ea, kJ mol-1) that correspond to critical temperatures ranging from 28 to 33°C. The generation mechanisms of induction transients A, B, C, D and E classify them into two groups. Transients A and B are of a physical character, while the transients: C, D, and E are of a chemical character. It is shown that the generation of the induction transients: B, C, D and E simultaneously follows establishing of the oscillations of induction processes of the DF chlorophyll. Oscillating of induction processes of DF chlorophyll is explained by the ion (K+, Na+, H+, Cl-) transport mechanism across the thylakoid membrane of the intact leaf of maize inbreds and hybrids grown under conditions of air drought, increased temperatures and water deficiency in the medium.

AB  - Maize has poor nutritional value due to deficiency of two essential amino acids - tryptophan and lysine. Although recessive opaque2 (o2) mutation significantly increases their content in the endosperm, incorporation of opaque2 into high yielding cultivars was not commercially successful, because of its numerous agronomic and processing problems due to soft endosperm. Quality protein maize - QPM has lately been introduced as opaque2 maize with improved endosperm hardness and improved agronomic traits, but mostly within tropical and subtropical germplasm. The ongoing breeding project at MRI includes improvement of MRI opaque2 lines and conversion of standard lines to QPM germplasm. The main selection steps in QPM breeding involve assessing kernel modifications and tryptophan level in each generation. Herein, we present the results of the analysis for these traits on F3 and BC1F1 generations of QPM x opaque2, opaque2 x QPM and standard lines x QPM crosses. The results showed that the majority the genotypes had kernel types 2 and 3 (good modifications). The whole grain tryptophan content in F3 and BC1F1 genotypes of crosses between QPM and opaque2 germplasm was at the quality protein level, with a few exceptions. All BC1F1 genotypes of standard lines x QPM had tryptophan content in the range of normal maize, while majority of F3 genotypes had tryptophan content at level of QPM. The progeny (with increased tryptophan levels) of QPM and opaque2 crosses had significantly higher tryptophan content compared to the progeny of crosses between standard and QPM lines - 0.098 to 0.114 and 0.080, respectively. All genotypes that had poorly modified kernels and/or low tryptophan content will be discarded from further breeding.
AB  - Iako recesivna opaque2 (o2) mutacija značajno povećava sadržaj lizina i triptofana u zrnu kukuruza, inkorporacija opaque2 u visoko prinosne genotipove nije uspela, zbog brojnih problema koji su se javili kao posledica mekog endosperma. Kukuruz visokog kvaliteta proteina (QPM) je opaque2 kukuruz sa poboljšanom tvrdoćom zrna i dobrim agronomskim performansama, stvoren prvenstveno od tropske i subtropske germplazme. U Institutu za kukuruz je u toku projekat koji za cilj ima poboljšanje sopstvenih opaque2 linija i prevođenje standardnih linija u QPM kukuruz. U ovom radu predstavljamo rezultate analiza modifikacije zrna i sadržaja triptofana u F3 i BC1F1 generacijama ukrštanja QPM x opaque2, opaque2 x QPM i standardne linije x QPM. Većina genotipova je imala zrno tipa 2 i tipa3 (dobre modifikacije). Sadržaj triptofana u celom zrnu genotipova ukrštanja QPM i opaque2 linija je bio na nivou karakterističnom za QPM, sa nekoliko izuzetaka. Sadržaj triptofana u potomstvu ukrštanja standardne linije x QPM je bio povećan kod većine F3 genotipova. Potomstvo (sa povećanim sadržajem triptofana) ukrštanja QPM i opaque2 linija je imalo znatno veći sadržaj ove aminokiseline u odnosu na potostvo ukrštanja standardne linije x QPM - - od 0.098 do 0.114 prema 0.080. Genotipovi sa lošim modifikacija zrna i/ili niskim sadržajem triptofana ce biti eleminisani iz daljeg procesa selekcije.

AB  - The activities of antioxidative enzymes and contents of proline and total phenolics were assayed in roots of two maize (Zea mays L.) genotypes grown in a medium containing nitrate (NO3 (-)) or both nitrogen forms, nitrate and ammonium (NH4 (+)/NO3 (-)). An increase in the activities of class III peroxidases (POD), superoxide dismutase (SOD), ascorbate peroxidase (APX), ascorbate oxidase (AO) and proline content, and decrease in phenolic content were observed in NH4 (+)/NO3 (-) in comparison with NO3 (-) grown plants. When polyethylene glycol (PEG) was added to both nitrogen treatments, the content of total phenolics and proline was increased, especially in NH4 (+)/NO3 (-) treatment. The PEG treatment decreased enzyme activities in NH4 (+)/NO3 (-) grown plants, but in NO3 (-) grown plants activities of POD and SOD were increased, opposite to decreased APX and AO. Isoelectric focusing demonstrated increased activities of acidic POD isoforms in PEG treated NO3 (-) grown plants, and lower activities of both, acidic and basic isoforms in NH4 (+)/NO3 (-)grown plants.

AB  - Maize Research Institute (MRI) gene bank maintains a collection of 6000 maize accessions. Within this collection over 100 sources of cytoplasmic male sterility (CMS) were found in field trials, i.e. more than 2% of the total accession numbers. These sources are distributed among Yugoslav open-pollinated varieties (4.56% of them contain CMS), as well as introduced heterozygous genotypes and inbred lines. In order to identify cytoplasm types the gene-bank sources of CMS were screened using a PCR assay with specific primers for C, T and S cytoplasms. Predominant cytoplasmic male sterility type among the analyzed accessions was CMS-S. Results were inconclusive for three accessions, i.e. different results for the progenies of two ears per accession were obtained. For another two accessions a new PCR product profile was identified, consisting of one band characteristic for CMS-S and one unspecific for any of the three CMS types. The PCR approach enabled a simple, fast and reliable large scale screening of maize cytoplasm among MRI gene bank accessions, significantly reducing time for cytoplasm characterizations compared to classical method of testing with restorers for each known type of CMS.
