In order to access and selection promised chickpea cultivars of cold tolerant and adapted to the cold weather conditions, this study carried out with 13 chickpea lines along with three local check in a RCB design with four replications during two cropping seasons (2017-2019) in two cold location (Maragheh and Urmia). Combined analysis of variance showed that there were significant differences in among the genotypes for most traits including grain yield. Mean comparison of grain yield showed that lines No. 1, 2, 5 and 11 had more grain yield (more than 1400Kg/ha) than Saral check (846 kg/ha). The results of this study showed that FLIP 09-78C had the highest tolerance to cold. Based on ranking method, FLIP 09-78C with 2.9 had the lowest ranking. Evaluation of yield stability of genotypes with using of among years variance (S2y) showed that lines No. 2, 5 and 11 with 0.135, 0.111 and 0.218 had low variance, respectively; and they were the most stable genotypes. The conclusion of results based on variance of among environments, ranking and CV methods showed that FLIP 09-78C was the most stable genotype
