The present experiment was carried out in randomized complete block designs with 3 replications during 2018-2019, 2019-2020 under rain-fed conditions (in two regions of cold dryland areas including Zanjan, Maragheh (total of 4 environments) . The combined analysis of variance for grain yield showed significant differences for year, genotype, genotype × year, year × location effects. The first and second components in AMMI model accounted for 83.3% and 10.92% of the interaction sum of squares, respectively. Considering the numerical values of interaction for each genotypes and genotypes rank, genotypes G3 ،G17 ،G1 ،G7 ،G14 and G18 were found to be more stable genotypes. Also, based on AMMI stability value (ASV), genotypes G11 ،G8 ،G14 ،G10 ،G20 and G3 were determined as stable genotypes. Among stable genotypes, genotypes G18 ،G1 ،G20 ،G17 ،G14 ،G4 ،G7 ،G2 and had higher mean grain yield. Therefore, these genotypes can be proposed for using in future breeding programs to introduce new cultivars.
