AB  - Maize genotypes have varied reactions in different localities, years, treatments or the combination of these factors, due to genotype x year interaction. The objective of this study was to estimate genotype by locality, by year, by treatments (GxLxYxT) interaction using AMMI model, to identify maize genotypes with stable and high yield performance in different growing seasons. The trials with seven maize lines/genotypes were conducted during two years (2010-2011) at the four treatments and two locations: Pancevo and Zemun Polje. The results showed that the influence of: genotype (G), locality (L), treatment (T) and GxL, GxT, YxL, YxT, LXT, GxYxT, GxLxT, YxLxT, GxYxLxT interaction, on maize yield were significant (p lt 0.01). The share of genotype for maize grain yield in the total phenotypic variance was 21.16%, the aggregate share of the years and the locality was 6.10%, the treatment was 18.22%, and the total interaction was 54.52%. The AMMI analysis of the main components of IPCA1 and IPCA2 for the interaction of GxL and GxT shows that the first major component, IPCA1, comprises 100% of the sum of the squared interaction GxL and showed a statistically significant effect. The results also show that the sums of the squares of the first and second major components (PC1 and PC2) constitute 100% of the sum of the squared interaction GxL. The IPCA1 share in the GxT interaction was 47.39% and the IPC2 was 37.94%. IPC1 and IPC2 for this interaction was 85.33%. A high level of IPC2 indicates a significant treatment effect. The results of AMI analysis show that there is a significant difference between the genotype reactions to different ecological conditions for investigated factors. It also provided better insight in specific association between maize grain yield, locality, treatment and meteorological variables. Among the tested maize lines/genotypes, L-5, L-4 and L-6 could be separated as highest yielding genotypes, however L-5 could be recommended for further breeding program and in large-scale seed production due to its stable and high yielding performance.

AB  - Eight maize inbred lines of different cycles of selection, originating from synthetic populations BSSS and BSCB1, were observed in the present study. The aim of the study was to evaluate inbreds and to determine which ones have the greatest relative values of favourable alleles for the improvement of the kernel row number in the elite single cross maize hybrid. Based on the estimated estimators: mu G, UBND, PTC and NI, it was determined that the greatest number of favourable dominant alleles for the improvement of the kernel row number was detected in the inbred lines B73(C-5) and B84(C-7) originating from the synthetic population BSSS and in the inbreds B91(C-8) and B90(C-7) originating from the synthetic population BSCB1. These inbreds are of the later cycles of recurrent selection and have proven to be better donors of favourable alleles than inbreds of earlier cycles of selection. The rank correlations among used estimators were positive and highly significant, while the highest values of correlations for the kernel row number were determined between mu G and PTC, mu G and UBND and PTC and NI. The greatest kernel row number was determined in the hybrid B73(C-5) x B84(C-7).
