Abstract

The interaction of genotype and environment is one of the most important topics and challenges of plant breeding researchers, this research was performed on twenty-eight bread wheat genotypes from two alleles and their parents in six different environments in two consecutive years of investigation of performance stability. The experiment was conducted as a randomized complete block design with four replications. Performance, stability analysis was performed using multivariate parametric methods (AMMI and GGE-biplot). The main effect of genotype and environment on the results of AMMI analysis was significant at the 1 % level, the main components of PC1 and PC2 have used for biplot, based on parameters of AMMI model stability analysis, genotypes 25, 16, 6, 27 were selected as stable genotypes. Based on the results of graphical analysis of genotype interactions ×environment using GGE-biplot genotypes 18, 17, 14, 15, 20 were selected as stable genotypes, where the location of Zabul is different from the others.
