AB  - The herbicide application and crop arrangement modifications are measures that can reduce weed abundance and support maize to compete over weeds. The aim of the investigation was to test and compare the growth and yield parameters of maize cultivated with standard and narow distances and with pre- and post-emergence chemical weed control. The experiment was conducted in the MRI Zemun Polje, Belgrade, during 2014-2016. Maize hybrid ZP 388 was grown with 50 cm and 70 cm row spacing, i.e 59,500 and 83,333 plants ha-1, respectively. The herbicide treatments included: control, a pre-emergence treatment of S-metolachlor+mesotrione and the post-emergence application of nicosulfuron+mesotrione. Six weeks after herbicides application, the biomass of whole maize plant (BMP) was measured, while the chlorophyll content (CH), leaf area (LA) and the leaf area index (LAI) were evaluated at the stage of fully developed maize plants. The Harvest index (HI) and grain yield (GY) were measured at harvest. The herbicide application caused significant differences in all maize parameters. The BMP, CH, LA, LAI, HI and GY were the highest when the post-emergence herbicides treatment was applied (25.22 g, 61.16, 4545.76 cm2, 3.22, 0.46 and 9.56 t ha-1, respectively) and the lowest in control (15.21 g, 49.35, 3356.02 cm2, 2.39, 0.41 and 5.87 t ha-1, respectively). Maize cultivation with 70 cm row distance was significantly advantageous for LA, HI and GY, (4316.33 cm2, 0.45 and 9.19 t ha-1, respectively) in comparison to the 50-cm row distance (3940.96 cm2, 0.43 and 7.36 t ha-1, respectively). The post-emergence herbicide application and standard 70-cm row distance are beneficial for the growth and yield of the hybrid developed under agro-ecological conditions of Serbia.

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  - 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  - Water deficit is one of the main limiting factors leading to maize yield reduction in the temperate zone. Global environmental changes additionally put breeding for drought tolerance in the focus of research programmes. In improving drought tolerance of elite hybrids, the first step is identification of drought tolerance sources within the existing gene bank collections. The complete gene bank collection of the Maize Research Institute, Zemun Polje, Serbia, was field tested under extreme water deficit in Egypt, with the aim of identifying tolerant genotypes. Six quantitative traits and a general estimation of the plant habitus during the growing season were estimated. Genotypes were classified by two-step cluster analysis. In the first phase of data analysis the classification was done with four quantitative and one qualitative trait, genotypes being classified into two clusters. In the second phase when the analysis included the duration of the growing season, genotypes were classified into three clusters. The first phase of data analysis pointed out to 231 drought tolerant genotypes, while the second phase data analysis further added a certain number of early and medium early genotypes, giving a total of 558 accessions. Further work on the selected accessions will be continued for the formation of the core collection and direct use in breeding.

AB  - It is generally known that a phenotype is formed on the basis of the capacity of its genotype affected by environmental factors. Yield stability is statistically expressed through the GxE interaction. The interaction is a part of the trial variation that includes the factor of the genotype and the factor of the environment. The presence of the qualitative interaction significantly makes difficult the selection of the best genotypes in the process of breeding. As long ago as the early 1960s, many researchers noticed that the application of linear regression could, in many cases, define adaptability and stability of a genotype. However, in cases when data are not well adjusted to the linear model, better results can be gained by the application of the multivariate models (PCA, AMMI, GGE). The estimated maize hybrid stability was compared in this study by linear (Finlay and Wilkinson and Eberhart and Russell models) and multivariate statistical models (AMMI model). Very similar results were obtained by all three models. It was probably due to one dominant factor in the hybrid x environment interaction (different precipitation sums for the environments and the length of the growing season for hybrids). The advantage was given to the AMMI model, as the model with one axis analyses the interaction equally well as linear models, while the model with two axes extracted another part of systemic variation of the interaction effect not adjusted to the linear model.

AB  - Eight BSSS and BSCB1 inbred lines of different cycles of selection were studied with the aim to evaluate which inbreds had the highest relative values of favourable alleles for the improvement of the grain yield trait in an elite single cross maize hybrid. Based on estimated parameters μG, UBND, PTC and NI it was determined that the inbreds B73 (C5) and B84 (C7), originating form the synthetic population BSSS had highest number of favourable alleles for the improvement of the grain yield. Both these inbreds belong to the later cycles of recurrent selections and proved to be better donors of favourable alleles than inbreds belonging to the earlier cycles of selection. The rank correlations of used parameters were positive and highly significant, while the highest values of correlations for yield were determined between μG and NI, that is PTC and NI. The highest grain yield was recorded in the hybrid ZPL2 x B73, which also had the highest value of heterosis (174.9%) in the trial for estimation of loci relative values.

Na osnovu izračunatih parametara μG*, UBND, PTC i NI utvrđeno je da najveći broj poželjnih dominantnih alela za popravku prinosa zrna pokazale su inbred linije B73(C5) i B84(C7) iz sintetičke populacije BSSS.

AB  - The organisation of germplasm into genetically divergent groups is of extreme importance for the development of hybrid varieties in which the identification and exploitation of heterosis is very important for the final result of breeding. It can also be beneficial for breeding of self-pollination varieties, clones and synthetics. The discovery of heterotic groups in standard grain quality maize significantly improved the process of testing. The improvement in sweet maize was relatively modest in comparison to standard grain quality maize due to a relatively narrow genetic base of sweet maize, then poorly defined heterotic relations, scarce sources of germplasm that satisfy commercial standards, poor seed vigour, low quality of root and stalk, as well as, a short period of time for the estimation of yield and quality. The efficiency of hybrid breeding programmes would be significantly higher if heterosis could be predicted prior to the evaluation in the field. The application of the multivariate analysis method to data of phenotypic characterization according to the UPOV Descriptor was an attempt to establish whether such a procedure can be beneficial for the determination of related groups and whether the phenotypic distance, obtained on the basis of a visual estimation of a plant group, can be an indicator of heterosis. Obtained results indicate that clustering is highly analogous to the pedigree. Since sweet maize breeders have at their disposal less significant genetic variability and search for the development and defining of heterotic groups, as such a procedure can be useful in both, the process of the hybrids development and the process of new inbreed development and genetic variability increasing. Certainly, further systematic studies aimed at this direction are necessary to reliably ascertain that the phenotypic distance is a justifiable indicator of heterosis.

AB  - Due to an unknown mechanism of genetic control and great environmental effects in the process of trait expression, morphological markers are often considered unreliable indicators of genetic relationships. Morphological characterization of 19 maize inbreds was done according to the UPOV descriptor, while molecular characterization was performed with RAPD markers. Based on the estimation of phenotypes according to the UPOV descriptor, the squared Euclidean distance was calculated and then, on the basis of this distance, a morphological similarity matrix was formed. Jaccard similarity coefficients were calculated on the basis of presence absence of bands on gels in the RAPD analysis. When data were standardized, the comparison between morphological and genetic similarity of observed maize inbreds was done. The correlations varied from 0.47 (inbred L 217) to 0.76 (inbred L 86). The average value of correlations for all studied inbreds amounted to 0.64. Furthermore, the results of the cluster analysis for both markers, molecular and morphological, had high concordance with pedigree data. Environmental effects were decreased in morphological markers (according to the UPOV descriptor) by rescaling a measurement scale from a scale to an ordinal level of measurement and in such a way results of morphological markers approached results of molecular markers in the estimation of the genetic distance (GD) of maize inbred lines.
AB  - Zbog nepoznatog mehanizma genetičke kontrole i velikog uticaja spoljne sredine u procesu ekspresije svojstava, o morfološkim markerima se cesto govori kao o nepouzdanim pokazateljima genetičkih odnosa. Morfološka karakterizacija 19 linija kukuruza je urađena po UPOV deskriptoru, vizuelnom ocenom grupe biljka, dok je molekularna karakterizacija urađena RAPD markerima. Na osnovu ocena fenotipa po UPOV deskriptoru izračunati su kvadrati euklidskog rastojanja na osnovu kojih je formirana matrica morfoloških sličnosti. Na osnovu prisustva-odsustva traka na gelovima u RAPD nanalizi izračunati su koeficijenti genetičkih sličnosti po Jaccardu. Nakon toga vršena su poređenja morfoloških i genetičkih sličnosti ispitivanih linija kukuruza. Korelacije su se kretale od 0.47 za liniju L 217 do 0.76 za liniju L 86. Prosečna vrednost korelacija za sve ispitivane linije je iznosila 0.64. Rezultati klaster analize, kako za molekularne tako i za morfološke markere, bili su u visokoj saglasnosti sa pedgre podacima. Degradiranjem merne skale sa skalnog na ordinarni nivo merenja, kod morfoloških markera (po UPOV deskriptoru), je ublažen efekat spoljne sredine. Na taj način su se rezultati morfoloških markera približili rezultatima molekularnih makera u proceni GD inbred linija kukuruza.

abstract = "Due to an unknown mechanism of genetic control and great environmental effects in the process of trait expression, morphological markers are often considered unreliable indicators of genetic relationships. Morphological characterization of 19 maize inbreds was done according to the UPOV descriptor, while molecular characterization was performed with RAPD markers. Based on the estimation of phenotypes according to the UPOV descriptor, the squared Euclidean distance was calculated and then, on the basis of this distance, a morphological similarity matrix was formed. Jaccard similarity coefficients were calculated on the basis of presence absence of bands on gels in the RAPD analysis. When data were standardized, the comparison between morphological and genetic similarity of observed maize inbreds was done. The correlations varied from 0.47 (inbred L 217) to 0.76 (inbred L 86). The average value of correlations for all studied inbreds amounted to 0.64. Furthermore, the results of the cluster analysis for both markers, molecular and morphological, had high concordance with pedigree data. Environmental effects were decreased in morphological markers (according to the UPOV descriptor) by rescaling a measurement scale from a scale to an ordinal level of measurement and in such a way results of morphological markers approached results of molecular markers in the estimation of the genetic distance (GD) of maize inbred lines., Zbog nepoznatog mehanizma genetičke kontrole i velikog uticaja spoljne sredine u procesu ekspresije svojstava, o morfološkim markerima se cesto govori kao o nepouzdanim pokazateljima genetičkih odnosa. Morfološka karakterizacija 19 linija kukuruza je urađena po UPOV deskriptoru, vizuelnom ocenom grupe biljka, dok je molekularna karakterizacija urađena RAPD markerima. Na osnovu ocena fenotipa po UPOV deskriptoru izračunati su kvadrati euklidskog rastojanja na osnovu kojih je formirana matrica morfoloških sličnosti. Na osnovu prisustva-odsustva traka na gelovima u RAPD nanalizi izračunati su koeficijenti genetičkih sličnosti po Jaccardu. Nakon toga vršena su poređenja morfoloških i genetičkih sličnosti ispitivanih linija kukuruza. Korelacije su se kretale od 0.47 za liniju L 217 do 0.76 za liniju L 86. Prosečna vrednost korelacija za sve ispitivane linije je iznosila 0.64. Rezultati klaster analize, kako za molekularne tako i za morfološke markere, bili su u visokoj saglasnosti sa pedgre podacima. Degradiranjem merne skale sa skalnog na ordinarni nivo merenja, kod morfoloških markera (po UPOV deskriptoru), je ublažen efekat spoljne sredine. Na taj način su se rezultati morfoloških markera približili rezultatima molekularnih makera u proceni GD inbred linija kukuruza.",
