Chickpea (Cicer arietinum L.) is traditionally grown as a rain fed crop globally, specifically in Middle East. Its seed is a rich source of protein for human consumption in developing countries such as Iran. The development of genotypes, which can be adapted to a wide range of diversified environment, is the ultimate goal of plant breeders in a crop improvement program. In this study, several univariate and multivariate stability methods were used to evaluate the genotype × environment (GE) interaction in 17 chickpea genotypes. Field experiments were carried out in 16 environments of Iran’s chickpea producing areas to characterize GE interaction on grain yield of 17 chickpea genotypes. Combined analysis of variance across environments indicated that both environments and GE interactions influenced significantly the genotypes performance for yield. Twenty univariate and multivariate stability methods and techniques were used to describe the GE interaction and to define stable genotypes in relation to the yield considered in this study. The different stability statistics which measured the different aspects of stability was substantiated by Spearman’s rank correlation coefficient. According to Spearman’s rank correlation coefficient three groups of stability parameters can be defined that the results of these different stability methods were variable. We used group 1, include Lin and Binns superiority measure ( i P ), Hernandez et al (1993) parameter ( i D ), GGE Biplot method and Principal coordinate method for introduction some genotypes to farmers. The identified superior genotypes significantly differ from the local check cultivars and therefore farmers in semi arid areas of Iran can use these genotypes.
