   In order to investigate the effect of genotype, environment and the interaction of genotype × environment, for seed yield, 18 lentil genotypes in a randomized complete block design with three replications in four environments (Khorramabad, Gachsaran, Ilam and Gonbad) during three years (2014-2017) Were evaluated. Based on combined analysis of variance, the main effects of location, genotype and genotype × location and genotype × location × year interactions were significant. The results of combined analysis of variance for different environments showed that environment, genotype and genotype × environment interaction for Showed seed yield. According to the results of AMMI analysis of variance, the environment was the main source of change, which accounted for 83.6% of the total squares. The results of AMMI analysis of variance also showed that the four-component interaction effect on seed yield was significant. The first two main components of the AMMI model accounted for 52.56% of the total yield variance. The results of AMMI stability values (ASV) showed that for seed yield, the genotypes including G8, G7, G9, G18, G6, G16 and G17 had the lowest values and therefore the highest general stability to all experimental environments. Genotype G5 with ASV value of 33.7 was highest private stability to the second environment (E2). Among the genotypes with the lowest ASV, only G6 and G16 genotypes had higher average seed yield than the average of all genotypes. Based on the values of the first two principal components, AMMI (ASV) stability value and genotype stability index (GSI), the genotypes G6, G1 and G13 were identified as the most stable genotypes, and the closest genotypes to the ideal genotype.
