Evaluating of the chickpea genotypes under different environmental conditions would be useful to identify genotypes with stable and high yield potential. The purpose of this study was to identify high yielding genotypes, cold tolerant and stable types for sowing in cold regions of Iran. The experiment was conducted using thirteen chickpea genotypes in randomized complete block design with four replications in four cold regions of Iran including Maragheh, Kurdistan, Urmia, and Hamedan during three successive cropping seasons (2017-2020) in autumn planting under dryland conditions. Among the chickpea genotypes, the highest and lowest average seed yield obtained in G1 (893 kg.ha-1) and G9 (744 kg.ha-1), genotypes, respectively. The contribution of environments (E), genotypes (G), and genotype × environment interaction (GEI) to the total variation in seed yield was 68.4%, 1.21% and 10.30%, respectively. According to singular value partitioning, the first two principal components explained PC1=42.86% and PC2=27.88% of total variations in data of seed yield. On the basis of GGE biplots, G1, G3 and G8 had high seed yield and yield stability as compared to the other genotypes. In conclusion , G1, G3 and G8 with high mean yield and stability performance can be used in selection/ recommendation process of cultivar.
