This paper aims at determining the genotype x environment interactions of seed yield and quality components of NS soybean cultivars under different agroecological conditions. Field trials were conducted in Serbia, during three years (2009-2011). Six soybean genotypes, belonging to different maturity groups were used (MG): Valjevka, Galina, Afrodita (0 MG), Sava, Victoria (I MG) and Trijumf (II MG). The effect of genotype (G), environment (E) and GxE interactions on yield, protein content and oil content were found to be significant (P<0.05, P<0.01). During 2010 and 2011, significantly higher grain yield per area unit were achieved as compared to 2009. The highest stability of protein content in the whole tested period was found in genotype Galina. The highest seed yield and oil content were obtained by genotype Valjevka. Genotype Galina showed high stability and good performance in all years for seed yield and protein content. Soybean yield was positively significantly correlated with precipitation (r=0.48*) and negatively significantly correlated with temperatures (r=0.52*). Oil content was negatively highly significantly correlated with precipitation (r=0.83**) and positively highly significantly correlated with temperatures (r=0.81**). This study can represent the basis for further soybean breeding.
