Expansion and intensification of cultivation are among the predominant global changes of this century. Constant growth of the world population and rising demand for food conditional on improving the quality /quantity of crop products. This could be achieved by synergy among breeding improvement and dedicated seed production. Accordingly, advanced and modern production of bread wheat allows the creation of new genotypes with better adaptability to different environmental conditions. The aim of this study was to investigate the influence of genotype, environment and their interactions on yield and randman of seed using AMMI model. Ten bread wheat varieties were investigated (Evropa 90, NSR 5, Pobeda, Renesansa, Ljiljana, Cipovka, Dragana, Simonida, NS 40S and Zvezdana) across three growing seasons (2009/10, 2010/11, 2011/12) and two locations (Novi Sad and Pančevo). Based on the interaction of genotypes and agro-ecological environments for yield and randman of seed on AMMI1 biplot it was noted that the genotypes differed more in several multivariate part of the total variation than in additive effect.
