To study genotype, environment and genotype × environment interaction effects for seed yield on chickpea, eighteen chickpea genotypes were evaluated in four locations (Khoramabad, Ilam, Gachsaran, and Gonbad) for two cropping seasons (2014-2016). The experiment were conducted using a randomized complete block design with three replications. Combined analysis of variance for seed  yield showed that the main effects of location, year,location ×year , genotype, genotype × year, genotype × location, genotype× year× location interaction effect, were highly significant. Location and year  main effect were the main source of variation that accounted for 86.1% of the total yield variation. Analysis of variance of additive main effects and multiplicative interaction (AMMI) showed that the first two IPCAs were significant and explained 79.3% of the total yield variation. The results of AMMI (ASV) stability values indicated that for seed yield, genotypes 16, 4, 6 and 1 had the lowest value and therefore the highest general stable for all test environments and genotype G10 with a value of 12.89 of the highest were highly adapted to environment (E4). Based on the values of the first two principal components, AMMI stability value (ASV) and genotype stability index (GSI), genotypes G12,G13 and G6 were identified as the most stable medium yielding genotype respectively (1438.9,1266.3 and 1434.2  kg / ha) and the closest genotype to ideal genotype.
