The chickpea crop is highly sensitive to temperature and other climate condition. Genotype × environment interaction (G x E) is a major constraint to identify single superior genotype for a number of variable environments. Present study was undertaken for estimation of the impact of G x E interaction on seed yield of chickpea and to identify relatively stable genotypes across environments using 40 chickpea genotypes. Data were collected on twelve yield related traits. The variability analysis revealed that the PCV was higher in magnitude than its corresponding GCV for all the characters studied under three environments. This indicates the influence of the environment on the expression of these characters. Characters showing high heritability coupled and high genetic advance as percentage of mean were biological yield per plant (97.8% & 108.2%), seed yield per plant (97.3% & 104%) and total number of pod per plant (95.5% & 83%) in all the three environments and pooled analysis. The genotypes namely GG 2, ICC 4958, ICC 8474, ICCL 81248, ICCV 07102, ICCV 07109, ICCV 07110, ICC 1882, JG 1307, MP JG 2003-115, MP JG 99-115, JG 130 and JAKI 9218 had the regression coefficients greater than one coupled with high mean values indicating specific adaptation of these genotypes for exploitation of character for seed yield per plant. The above results have provided the opportunity of growing chickpea under late planting condition in double cropping (after rice) and very late (after soybean-potato/garden pea).
