Abstract:

Evaluating both stability of performance and high yield is important issue in plant breeding program. The objective of this investigation was to compare ten stability parameters of the Additive Main effects and Multiplicative Interaction (AMMI) model for GE interaction of 18 bread wheat genotypes. Also, a new AMMI parameter as modified AMMI’s stability value (MASV) was introduced. The combined analysis of variance indicated that environments (E), genotypes (G) and GE interaction effects were significant, suggesting differential responses of the genotypes and the need for stability analysis. Analysis of variance for AMMI model revealed that five interaction principal components (IPCs) were significant by Gollob’s F- test and accounted for 84.5% of GE interaction. According to EVF, SIPCF and DF parameters of AMMI, genotype G8 had the highest stability with low mean yield and genotype G5 could be introduced as the most favorable genotype with both high mean yield and stability. Overall based on the all AMMI parameters, genotypes G3, G14, G16 and G17 were the most stable genotypes which had relatively high mean yield, except G14. Bootstrap resampling technique verified the correlation results among AMMI stability parameters and indicated that none of the stability parameters were correlated with mean yield. One cluster analysis for genotypes indicated that there were three major groups among genotypes while same analysis for AMMI stability parameters revealed two clusters.
