Abstract

This research was carried out to study stability analysis and comparison between some measures of stability from AMMI model in 17 chickpea genotypes, in RCBD with four replications in five different research stations of Iran across two years (2004-2005). Spearman’s rank correlation was used to measure the relationship between measures of stability from AMMI model. To understand better relationships among these methods, principal component analysis, was performed. The first two PCs explained 87.65% of the variance of original variables. The relationships among the different stability statistics from AMMI model are graphically displayed in a biplot of PC1 and PC2. The results also revealed that stability measures can be classified into three groups. The first group included, SIPC4, EV4, MASV, Dz4, AV (AMGE), Wi(AMMI) and FAi which were correlated with mean yield. The second group consists of ASV, Da4, Bi and Za4 which were correlated with mean yield too. Group 3 consist of FPi that was not associated with the more stability methods and mean yield. This measure may not be as good as the other methods. The results of the correlation matrix and the PC analysis between different measures of stability from AMMI model showed that all measures (except for FPi) can be used for evaluating the responses of chickpea genotypes to changing environments. Eventually, according to all measures of stability from AMMI model (except for FPi) and regarding the high mean yield, genotype G13 (FLIP 97-114) was recommended for national release in Iran, as it adequately demonstrated wide adaptation across environments.
