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  - Cold test (CT) is a valuable method of assessing maize seed vigour. Although widely used CT is not standardized because of variations in CT procedures. The objective of this study was to evaluate seed vigour of 15 maize inbred lines developed at the Maize Research Institute Zemun Polje, using two different substrates (soil and sand) in a severe CT (7.5°C for 10 days followed by 7 days at 20/30 °C). Statistical analysis showed that inbred lines differ significantly in seed vigour, and no difference between two applied substrates in CT. Coefficients of variation were lower in CT with sand (6.05 %), compared to the CT with soil (6.74%) due to variation in soil quality and presence of soil-borne pathogens. Both CT procedures were highly correlated with field emergence. Results of this research indicate that CT with sand is appropriate for testing maize seed vigour, with the potential for standardization.
AB  - Vigor semena je veoma važan parametar kvaliteta, jer ukazuje na sposobnost semena da klija u suboptimalnim uslovima (niska temperatura, visoka vlažnost zemljišta itd.). Hladni test je važan metod za utvrđivanje vigora semena kukuruza. Iako je dobar pokazatelj nicanja u polju, i koristi se širom sveta, hladni test nije standardizovan zbog razlika u proceduri (temperatura, vrsta i vlažnost supstrata). Cilj ovog rada bio je ispitivanje vigora semena samooplodnih linija kukuruza primenom dva različita supstrata (zemlja i pesak) u hladnom testu. Za ispitivanje je odabrano 15 samooplodnih linija kukuruza stvorenih u Institutu za kukuruz 'Zemun Polje'. Primenjeni su izrazito stresni uslovi ispitivanja u hladnom testu (10 dana na 7,5°C, a zatim 7 dana na 20/30°C). Statističkom obradom podataka utvrđeno je da su se samooplodne linije značajno razlikovale po vigoru semena tj. tolerantnosti na niske temperature u periodu klijanja i početnog porasta. Sa druge strane nije utvrđena značajna razlika između dva primenjena supstrata u hladnom testu. Prosečna klijavost 15 samooplodnih linija u hladnom testu sa peskom iznosila je 82,2%, a u hladnom testu sa zemljom 80,1%. Koeficijent varijacije je bio niži u hladnom testu sa peskom (6,05%), nego u hladnom testu sa zemljom (6,74%), što se objašnjava variranjem u kvalitetu zemlje i prisustvu zemljišnih patogena. Obe ispitivane procedure su postigle visoku korelaciju sa nicanjem u polju. Rezultati ovih istraživanja ukazuju na mogućnost korišćenja peska kao supstrata u hladnom testu, čime bi se ispitivanje vigora semena kukuruza znatno olakšalo, a ujedno bi se stekli uslovi za standardizaciju hladnog testa.

AB  - In this study 36 maize hybrids of different FAO maturity groups were observed in three successive years (2011, 2012 and 2013), on 8 locations. The main objective of this experiment was to observe the GxE interaction concerning yield, grain moisture, grain yield per ear and test weight. The experiment was set up according to the RCBD. Based on the obtained results average estimates, CV and overall ranking of hybrids were calculated. ANOVA was applied in order to estimate the effect of factors: genotype, environment and interaction. Thus the significance of all these factors was observed. Results of this research indicate the importance and necessity of performing multilocation and multiyear trials with the aim of observation and understanding the intensity of GxE interaction, as well as its influence on the grain yield and it components.
AB  - Istraživanje je obuhvatilo 36 hibrida različitih FAO grupa zrenja, u 2011, 2012 i 2013 godini, na 8 lokaliteta. U ogledu je ispitivana interakcija genotip x sredina u pogledu stabilnosti prinosa zrna, vlage zrna, težine zrna po klipu i zapreminske mase kukuruza. Ogled je bio postavljen potpuno slučajnom blok sistemu (RCBD). Na osnovu dobijenih podataka izračunate su prosečne vrednosti, pokazatelji varijabilnosti posmatranih osobina i ukupan rang hibrida, a analizom varijanse utvrđena je značajnost efekta genotipa, sredina i interakcija. Za sve proučavane agronomske osobine, analizom varijanse su utvrđene statistički visokoznačajne vrednosti genotipa, sredina i interakcije. Najviši prosečan prinos zrna u ogledu ostvaren je u 2011. godini (11,62 t/ha), a najniži u 2012. godini (6,90 t/ha). Najniži prosečan procenat vlage zrna kukuruza u ogledu ostvaren je u veoma sušnoj 2012. godini (14,86%), dok između vrednosti ostvarenih u 2011. godini (19,47%) i 2013. godini (19,52%) nije bilo značajnije razlike. Vrednosti težine zrna po klipu kukuruza bile su direktno srazmerne vrednostima prinosa. Najveća zapreminska masa zrna kukuruza ostvarena je u sušnoj 2012. godini (74,84 kg/hl), dok je najmanje izmerena u kišovitoj 2013. godini (70,47 kg/hl). Rezultati ovog istraživanja potvrđuju neophodnost izvođenja višelokacijskih i višegodišnjih ogleda u cilju što boljeg sagledavanja intenziteta interakcija genotip x sredina, i njihovog uticaja na prinos i komponente prinosa hibrida kukuruza različitih FAO grupa zrenja na teritoriji Srbije. Da bi proizvodnja kukuruza bila stabilna, farmerima koji nemaju mogućnost navodnjavanja, već kukuruz gaje u suvom ratarenju, treba savetovati da seju hibride različite dužine vegetacije.

AB  - Grain yield and some of the more important agronomic traits of four variants of a single cross maize hybrid, with different number of CTM (cycloxydim tolerant maize) alleles were studied, when different rates of herbicide Focus Ultra were applied. The active ingredient of this herbicide is cycloxydim, to which ordinary maize is susceptible. Obtained results show that resistance of maize to this herbicide can be achieved by the introduction of just one CTM allele (heterozygote) into a single cross maize hybrid, for the herbicide rates up to 4 1 ha(-1), that is die maximal dose proposed by producer to be used in practice. The CTM homozygote was tolerant up to the final observed rate of 10 1 ha(-1), but this dose is only of theoretical importance. From the breeding aspect, this facilitates the introduction of new inbreds into maize hybrids to create the DUO system (herbicide Focus Ultra for the protection against narrow-leaf weeds plus some of herbicides for the protection against broad-leaf weeds), in which one component already carries a CTM homozygous allele, while the other is crossed to it in order to develop an Ultra hybrid. Based on our results, it seems that it is better if female component carries a CTM homozygous allele - a very moderate positive female effect in the inheritance of maize tolerance to the active ingredient cycloxydim was revealed.

AB  - This study conforms our hypothesis that there are elite maize inbred lines, which can be considered actual and prestigious as they have not only a property of the water status and a greater grain dry down rate during the maturation period, but also a property of the efficient photosynthetic-fluorescence model that is successfully used in the contemporary processes of breeding, and thereby in the development of new and yielding maize hybrids. Presented results obtained on the dynamics of grain dry down during the maturation period and on photosynthetic-fluorescence parameters (temperature dependence of the chlorophyll delayed fluorescence intensity, the Arrhenius plot for the determination of critical temperatures, i.e. phase transition temperatures and the activation energy) show that properties of the observed inbreeds are based on effects and nature of conformational and functional changes occurring in their thylakoid membranes and other chemical structures of grain tissues. Summarized results of studies on actual and prestigious properties of maize inbreeds will contribute to more exact, rational and expeditious proceedings of contemporary processes of breeding.

AB  - Maize is one of the most important agricultural crops in the world, and also in our country. In Serbia, in last two decades maize is grown on the area from 1.2 to 1.3 million hectares, with the average production of 5.7 million tones per year. It is the fact that there are favorable natural conditions for its production in our country, but the grain yield fluctuates depending on rainfall quantities and especially rainfall disposition during the vegetation period. The purpose of this work is to establish the grain yield potential of ZP maize hybrids from FAO 400-700 maturing groups. Data from STRIP trails of six ZP maize hybrids (ZP 434, ZP 578, ZP 677, ZP 680, ZP 684 and ZP 704), from 16 locations during 3 years, are used in this work. Grain yield and grain moisture content were measured in six tested genotypes and analyze of variance was done with ANOVA statistical software. Results of this investigation showed that the hybrid ZP 434 had an average grain yield of 8.528 t·ha-1, which is not statistically significantly different from the grain yield of the hybrid ZP 684 which yielded 8.626 t·ha-1. At the same time, hybrid ZP 434 had the statistically significantly higher grain yield than the hybrids from FAO 700 maturing group. According to the presented results of lasting several years averages on several locations, we can conclude that the hybrids from FAO 400 maturing group have a grain yield potential at the same level as the hybrids from FAO 600-700 maturing group.
AB  - Kukuruz je jedan od najznačajnijih ratarskih useva ne samo u svetu već i u našoj zemlji. U Srbiji se kukuruz u poslednje dve decenije gaji na površinama od 1.2 do 1.3 miliona hektara, uz ostvarenu prosečnu proizvodnju od 5.7 miliona tona godišnje. Poznato je da kod nas postoje povoljni prirodni uslovi za njegovu proizvodnju, ali i to da su po godinama velika kolebanja prinosa zbog velike varijabilnosti u količini, a posebno u rasporedu padavina u toku vegetacije. Cilj ovog rada je da se utvrdi potencijal rodnosti ZP hibrida kukuruza, FAO grupa zrenja 400-700. U radu su korišćeni podaci proizvodnih STRIP ogleda šest ZP hibrida kukuruza (ZP 434, ZP 578, ZP 677, ZP 680, ZP 684 i ZP 704) sa 16 lokaliteta u toku tri godine. Praćen je prinos zrna i sadržaj vlage u zrnu šest ispitivanih genotipova, a analiza varijanse urađena je pomoću statističkog programa ANOVA. Rezultati istraživanja su pokazali da je hibrid ZP 434 ostvario prosečan prinos zrna od 8.528 t·ha-1 koji se nije statistički značajno razlikovao od prinosa zrna hibrida ZP 684 od 8.626 t·ha-1. U isto vreme hibrid ZP 434 imao je statistički značajno viši prinos nego hibridi FAO grupe zrenja 700. Na osnovu iznetih rezultata višegodišnjeg proseka na više lokacija može se zaključiti da hibridi FAO grupe zrenja 400 imaju potencijal rodnosti na nivou hibrida FAO grupe zrenja 600-700.

AB  - A new method of deriving maize inbreds lines over two generations by the development of dihaploids was presented in this paper. A German inbred line RWS was used as a haploid inductor. This inbred encompasses two marker genes: R1-nj, which colors the endosperm and the germ blue, and pl-1, which colors stalk purple. The RWS inbreds was used as a male component in the first generation for crosses to five genotypes developed from crosses of elite maize inbred lines (F1 generation). Gametes of these genotypes crossed to the inbred RWS resulted in a certain number of kernels with the white germ and blue stains on the endosperm, pointing out that the endosperm was fertilized, but the ovum was not. It remained haploid, and it was only stimulated to a further division and a formation of a haploid germ. Such developed kernels were germinated, then treated with colchicine and derived plants were planted in the field. This paper presents the percentage of both, haploid induction for each of five progenies and derived F1 plants. The percentage of the haploid production efficiency was estimated for each of five genotypes. The potential importance of this model in maize breeding and selection was discussed.
AB  - U radu je prikazana nova metoda dobijanja inbred linija kukuruza u roku od dve generacije putem stvaranja dihaploida. U ovu svrhu korišćen je induktor haploida, nemačka inbred linija RWS. Ova linija sadrži dva marker gena: R1-nj, koji ostavlja plavu boju na endospermu i klici, i pl-1, koji boji stablo u ljubičasto. RWS linija je u prvoj generaciji korišćena kao otac za ukrštanje sa pet genotipova dobijenih ukrštanjem elitnih inbred linija kukuruza (F1 generacija). Gamete tih genotipova ukrštene sa RWS linijom dale su izvestan broj zrna koja imaju plavo obojenje na endospermu, ali belu klicu, što je indikacija da je došlo do oplodnje endosperma ali ne i jajne ćelije. Ona je ostala haploidna, a samo je stimulisana na dalju deobu i formiranje haploidne klice. Ovako dobijena zrna su naklijana, a zatim tretirana kolhicinom i dobijene su dihaploidne biljke koje su posađene u polju. U radu je dat je procenat indukcije haploida za svako od pet potomstava i procenat dobijenih F1 biljaka. Za svaki od pet genotipova izračunat je procenat uspešnosti dobijanja dihaploida. Diskutovan je potencijalni značaj ove metode u selekciji kukuruza.
