Abstract:   (158 Views)
For assessment of genotype × environment (G × E) interaction effects and determination of the most sustainable genotypes 20 barely lines were analyzed in at eight different experimental field stations. The experiments were performed based on Randomized Complete Block Design (RCBD) with three replicates. Grain yield was obtained and the results of the combined analysis of variance revealed genotype, environment and genotype × environment interaction effects were highly significant. Genotypes yield means showed that the G1, G13 and G4 genotypes had the highest grain yield. AMMI model analysis was used to determine the magnitude and significance of the genotype × environments interactions and divided G×E interaction to two principle components that explained 46/48% and 19/52% of interaction effects respectively and residuals. Based on biplot and AMMI analysis G, G genotypes were selected as candidate's lines with both best performance and grain yield sustainability. The environment E5 with high IPCA 1 and low IPCA 2 had the highest effect on determination of genotypes. The genotype G20 was selected as candidate line with high grain yield performance and stability.
