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 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  - 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  - The obtained results confirm the hypothesis that there are maize elite inbred lines (ZPPL 62 and ZPPL 233) that are considered prestigious and are characteristic by their water status and a greater rate of a dry down during the grain maturation. Also, they are characteristic by their efficient photosynthetic-fluorescence photo-model, which is successfully used in the contemporary technological productions of maize hybrid seed. The presented results on the dynamics of grain dry down during the maturation period and on photosynthetic and fluorescence parameters: temperature dependency of the intensity of delay chlorophyll fluorescence, the Arrhenius plot for the determination of critical temperatures (phase transition temperatures), activation energy and the angle between the ear leaf and the stalk of the maize plant, show that traits of observed inbreds are mainly based on good effects and nature of conformational and functional changes that occur in their thylakoid membranes and other chemical structures of grain and leaf tissue. Some other properties of observed prestigious maize inbred lines relevant to the seed production were also analyzed in this study.
AB  - U ovom radu potvrđuje se hipoteza da postoje elitne samooplodne linije kukuruza koje se smatraju prestižnim i koje poseduju, kako svojstvo stanja vode i njenog bržeg otpuštanja iz zrna u periodu sazrevanja, tako i svojstvo efikasnog fotosintetično-fluorescentnog fotomodela, koji se uspešno koristi u savremenim tehnologijama proizvodnje hibridnog semena kukuruza. Izloženi rezultati o dinamici otpuštanja vode iz zrna u periodu sazrevanja i o fotosintetično-fluorescentnim pokazateljima: teperaturnoj zavisnosti intenziteta zakasnele fluorescencije hlorofila, Arenijusovim kriterijumom za određivanje kritičnih temperatura (temperature faznih prelaza), energija aktivacije i veličine ugla između lista na klipu i stabljike kukuruza, pokazuju da su svojstva proučavanih linija zasnovana na dobrim efektima i prirodi strukturnih i funkcionalnih promena, koje se odigravaju u njihovim tilakoidnim membranama i drugim hemijskim strukturama tkiva zrna i lista. U radu se analiziraju i druge relevantne semenarske karakteristike proučavanih prestižnih samooplodnih linija kukuruza.

Some other properties of observed prestigious maize inbred lines relevant to the seed production were also analyzed in this study., U ovom radu potvrđuje se hipoteza da postoje elitne samooplodne linije kukuruza koje se smatraju prestižnim i koje poseduju, kako svojstvo stanja vode i njenog bržeg otpuštanja iz zrna u periodu sazrevanja, tako i svojstvo efikasnog fotosintetično-fluorescentnog fotomodela, koji se uspešno koristi u savremenim tehnologijama proizvodnje hibridnog semena kukuruza. Izloženi rezultati o dinamici otpuštanja vode iz zrna u periodu sazrevanja i o fotosintetično-fluorescentnim pokazateljima: teperaturnoj zavisnosti intenziteta zakasnele fluorescencije hlorofila, Arenijusovim kriterijumom za određivanje kritičnih temperatura (temperature faznih prelaza), energija aktivacije i veličine ugla između lista na klipu i stabljike kukuruza, pokazuju da su svojstva proučavanih linija zasnovana na dobrim efektima i prirodi strukturnih i funkcionalnih promena, koje se odigravaju u njihovim tilakoidnim membranama i drugim hemijskim strukturama tkiva zrna i lista.

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.

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  - The delayed chlorophyll fluorescence method, as a non-invasive bioluminescence method, is recommended for the application in maize breeding and seed production in order to evaluate maize inbred lines for their resistance and adaptability to increased and high temperatures, as well as, to drought. The following thermal properties of the photosynthetic apparatus of the observed maize inbred lines: the temperature dependence within a range of 25-60°C, critical temperatures at which phase transitions occur in the thylakoid membrane were discovered and by means of it significant functional changes in the photosynthetic apparatus of observed maize inbred lines were detected. activation energies (Ea, kJ mol-1) alongside the straight lines prior and after critical temperatures were calculated. Ea are a measure of occurrence of chlorophyll DF recombination processes and by that a measure of the total changes in structure and functioning of the thylakoid membranes. Thylakoid membranes underwent significant conformational changes in the part following the maximum intensity, i.e. in the part of its sharp linear decline. Such a state fits more to a non-living than a living organism in relation to its both, structure and functions. Results and the discussion of presented parameters of total thermal processes of chlorophyll DF, such as: temperature dependence, critical temperatures and activation energy, can be an important factor for a more exact characterization of maize inbred lines in relation to their resistance and adaptation to temperature and drought, contributing to a rapider and more rational development of the selection process.

AB  - The application of the improved non-invasive photosynthetic-fluorescence method in maize breeding and seed production was observed in order to assess the resistance and adaptability of maize inbred lines to higher and high temperatures, as well as to drought. The studies were carried out with two maize inbred lines (ZPPL 115 and A 671). The thermal characteristics of the photosynthetic apparatus of the investigated maize inbred lines were determined as follows: temperature dependency range from 25 to 60oC, critical temperatures at which phase transitions take place in the thylakoid membrane, causing significant structural and functional changes in the photosynthetic apparatus of the investigated inbred lines, activation energies (Ea, kJ/mol) were calculated along the straight lines before and after the occurrence of the critical temperature. The activation energy (Ea) is a measure of the intensity of recombining responses to chlorophyll DF, and total changes in the structure and functioning of the thylakoid membranes. The results obtained and presented parameters of total photosynthetic and thermal processes of chlorophyll DF may contribute to a more accurate characterisation of maize inbred lines in respect to their resistance and adaptability to temperatures and drought. Consecutively, this can lead to a quicker and more rational improvement maize breeding and seed production.
AB  - Poboljšani neinvazivni fotosintetično-fluorescentni metod kandiduje se za primenu u oplemenjivanju i semenarstvu radi utvrđivanja ocene samooplodnih linija kukuruza na plastičnost, tolerantnost, otpornost i adaptivnost prema višim i visokim temperaturama, kao i prema suši. Utvrđene su termalne karakteristike fotosintetičnog aparata proučavanih samooplodnih linija kukuruza, i to: određena je temperaturna zavisnost u opsegu od 25 do 60oC, otkrivene su kritične temperature na kojima dolazi do faznih transformacija u tilakoidnoj membrani, a time i do značajnih strukturnih i funkcionalnih promena u fotosintetičnom aparatu ispitivanih samooplodnih linija kukuruza, obračunate su energije aktivacije (Ea, kJ/mol) duž pravih linija pre i posle pojavljivanja kritične temperature. Energija aktivacije (Ea) je mera nastajanja rekombinacionih reakcija povezanih sa uspostavljanjem ZF hlorofila, a time i ukupnih promena u strukturi i funkciji tilakodinih membrana. Ostvareni rezultati i diskusija izloženih parametara ukupnih fotosintetično-termalnih procesa ZF hlorofila mogu doprineti egzaktnijem karakterisanju ispitivanih samooplodnih linija kukuruza u odnosu na njihovu plastičnost, tolerantnost, otpornost i adaptivnost prema temperaturi i suši, što samim tim i doprinosi bržem i racionalnijem unapređenju procesa selekcije i produktivne semenske proizvodnje.

AB  - The genetic diversity of six maize inbred lines, as well as, the genetic similarity between parental inbred lines and heterosis for yield in their F1 crosses was studied. Three inbred lines (ZPL 142, ZPL 680 and ZPL 357/3) are of the BSSS origin and another three (ZPL 257/3, ZPL 17/5 and ZPL 173/3) are of the non-BSSS genetic background. Molecular markers provide a direct determination of a number for which two inbred lines are different for a given number of loci. Maize inbred lines were genetically characterized with RAPD markers. Genetic similarity among genotypes was done by a statistical analysis with NTSYSpc v2.0 and by the application of the cluster analysis. Parental inbred lines, 30 F1 crosses with reciprocals, were included in a randomized complete block design with four replications in two densities (44,640 and 64,935 plants ha-1) at the location of Zemun Polje in 2003 and 2004. The differences among genotypes (F1 and inbreds line per se), densities and years were statistically significant. The highest value of mid-parent heterosis (192.2 %), as well as, the best-parent heterosis (178.0 %) was obtained for the cross ZPL 173/3 x ZPL 680 over investigated densities and years. The Spearman's correlation coefficient was used to determine correlations between the values of heterosis obtained in the field experiment and the value of genetic distances based on RAPD markers. The obtained results indicate that RAPD markers can be used to study the genetic diversity of maize inbred lines, although their application in the prediction of heterosis for grain yield is limited.
AB  - U radu je ispitivana genetička različitost šest samooplodnih linija kukuruza na osnovu RAPD markera i odnos genetičke sličnosti između roditeljskih linija i heterozisa za prinos zrna u njihovim ukrštanjima (F1 hibridima). Roditeljske linije i 30 F1 hibrida, dobijenih ukrštanjem roditeljskih linija u potpunom dijalelu, su testirani po slučajnom blok dizajnu sa četiri ponavljanja u dve gustine useva (G1=44.640 i G2=64.935 biljaka ha-1) u Zemun Polju tokom 2003 i 2004. godine. Razlike u prinosu zrna između ispitivanih genotipova (F1 i samooplodne linije per se), ispitivanih gustina i spoljnih sredina su bile statistički značajne. Najveći heterozis dobijen je kod kombinacije ZPL 173/3 x ZPL 680 i u odnosu na vrednost srednjeg roditelja (192.2 %) i u odnosu na boljeg roditelja (178.0 %) u ispitivanim gustinama i godinama. Za određivanje korelacija između vrednosti za heterozis u kombinacijama dobijenim u poljskom ogledu i vrednosti genetičkih distanci izračunatih na osnovu RAPD markera korišćen je Spearman-ov koeficijent korelacije. Dobijeni rezultati ukazuju da se RAPD markeri mogu koristiti za ispitivanje genetičke divergentnosti samooplodnih linija kukuruza, mada je njihova primena za predviđanje heterozisa za prinos zrna ograničena.
