| In order to study of environment × genotype interaction and selection of stable and high yielding and cold tolerant chickpea lines, this study carried out with 13 chickpea genotypes along with one local check (Jam) in a RCB design with four replications during three cropping seasons (2009-2012) in agricultural research station of Maragheh (DARI). The genotypes were exposed to cold temperatures of -8.5, -11 and -12 ◦C without snow covering during 2009, 2010, 2011 winters. Combined analysis of variance showed that there were significant differences in grain and biomass yields and highly significant differences in other characteristics (100SW، PH، DF، DM، HI، PS، CT، CH% and PC2) between genotypes. Mean comparison of grain yield showed that FLIP 99-26C، FLIP 00-84C and FLIP 00-39C with 1017، 1013 and 977 Kg/ha had more grain yield than Jam check (973), respectively. The results of this study showed that almost all of genotypes endured -8.5 ◦C perfectly and FLIP 00-84C showed the highest tolerance to cold. Based on ranking method, FLIP 00-84C with 3.3 had the lowest ranking. Genotype No. 12 had the lowest SDR (0.57). Evaluation of yield stability of genotypes with using of among years variance (S2y) showed that genotypes No. 1, 2, 9 with 0.155, 0.196 and 0.217 had low variance, respectively; and they were the most stable genotypes. The conclusion of results based on variance of among years, ranking and CV methods showed that FLIP 00-84C was the most stable genotype. | ||
