Sažetak
Stability of 9 dry pea (Pisum sativum L.) genotypes across 2 locations, and 3 years with respect to grain yield were tested in east Croatia. The object was to assess genotype-environment interactions and determinate stable genotypes. The analysis of variance of the 9 genotypes in 6 environments shows that genotype (G), location (L) year (Y) and their interaction (GxL, GxY, LxY) were significant (P < 0.01) for dry pea grain yield. Significant GxL effects indicated the necessity for testing pea genotypes in Croatia at multiple locations.. The biplot shows that the genotypes Erbi and Bohatyr are best suited for cultivation in a wide range of environments. The genotype Primus is well-suited for cultivation in poor rainfalls environments. No genotype has superior performance in all environments.
