In order to evaluate the stability of the yield of lentil ecotypes in Qazvin province, an experiment in the form of a randomized block design was carried out in six planting dates (environment) with three replications at the soil and water conservation research station of Tehran University in Kohin rainfed lands. The results of composite variance analysis showed a significant difference between environments, genotypes and the interaction effect of genotype × environment.The analysis of additive main effects and multiplicative interaction effects (AMMI) showed that the grain yield of lentil genotypes is influenced by the environmental part of the interaction effect of genotype × environment. In the analysis AMMI of the sum of squares, 55.8% was caused by environmental effects, 27% by genotypic effects and 17.2 % were justified by the genotype × environment interaction. In the AMMI method, the FILIP 2003-9L genotype with favorable relative performance and the lowest estimate of stability value (ASV) was introduced as the most stable genotype and Sabz Pardis with the best performance and the highest estimate of stability value was introduced as the most unstable genotype. In the biplot analysis of the AMMI model, the genotype FILIP 2003-9L with favorable yield and low IPCA1 value, general stability in all conditions and Sabz Pardis genotype with the highest IPCA1, showed good private compatibility with Autumn cultivation.
