Grain yield and the two yield components were analyzed: the number of grains per spike and the weight of 1000 grains. Using the mixed model, the high significance (p<0,01) of the genotype effect and the interaction between the genotype and the environment was determined, while the effect of the environment is statistically significant (p<0,05). The interaction was analyzed using the AMMI-1 model. On the basis of the biplot, wide adaptability genotypes with stable and high average values of the examined trait were separeted. Genotype J-176 had wide adaptability for grain yield and genotype NS- 595 stood out for the number of grains per spike. Genotype NS-565 was superior in weight of 1000 grains. On the basis of the difference in the interaction effect of the environments and their stable, suitable localities were also selected for testing the characteristics. Not a single location stood out as suitable for testing the grain yield and number of grains per spike, while Zaječar was suitable for testing the mass of 1000 grains.
