In order to reach the genotypes of chickpea, a more efficient quality of chickpea genotypes than existing cultivars possessing suitable traits such as seed yield, number of pods per plant, coarse grains, agronomy and other agronomic traits, 18 advanced chickpea genotypes were selected from advanced trials 2014-2015 agronomic year by control cultivars Adel and Azad for three crop years (2016-2019) in Gachsaran, Gonbad, Khoramabad and Ilam regions were planted in a completely randomized block design with three replications. There are several methods for determining the interaction of genotype × environment, the most important of which are parametric, nonparametric and multivariate methods. In this research, AMMI and site regression (biplot) methods were used to analyze genotype × environment interactions. In the multivariate method, the main additive effects and multiplicative interactions (AMMI) used in this study, genotypes 13, 15, 9, 12 and 16 with the lowest rank values and the highest average grain yield were in the group of stable genotypes. In spatial regression method, genotypes 13, 15, 12 and 7 were selected as the most stable genotypes with the lowest share in the interaction of genotype and environment. According to the obtained results, genotypes 13, 15, 9, 12, 7 and 16 were selected as promising genotypes and candidates for introduction.Key words: Chickpea, Yield Stability, AMMI, Biplot.
