Given the global climate change and frequent episodes of high temperature, globally legume crops including chickpea are receiving serious challenge of yield loss across the globe. Therefore, to sustain chickpea production breeders exploiting existing germplasm resources which can withstand drastically happening and fluctuating abiotic stresses like terminal heat and draught. A wide range of genetic variability for various phenological traits and yield related traits were recorded in 71 chickpea genotypes during normal and late or terminal heat stress sown conditions. The analysis of variance for all the environments revealed highly significant differences among the mean square due to genotypes for all the characters. The range of variation was comparatively wider in late sown condition than in normal sown conditions. The differences between phenotypic and genotypic coefficient of variation (PCV and GCV) were not substantial. High heritability coupled with high/ moderate genetic advance expressed as percentage of mean were exhibited by hundred seed weight, seed yield/plant, number of pods/plants, plant height, reproductive phase duration, number of primary branches/plant and days to 50 % flowering under normal as well as late planting. So, these traits can be used as selection indices to improve seed yield in high temperature sown condition as well as timely sown condition. The pooled analysis of variance over dates of sowing (environments) were computed following Eberhart and Russell (1966) model. Genotype x environment interactions was highly significant for most of the characters except no. of primary branches/plant when tested against error mean square. G x E (linear) component was significant and higher than nonlinear component for days to 50 % flowering, days to maturity, number of pods/plants, hundred seed weight and seed yield per plant. From the present study, five genotypes viz., ICC 14778, GJG 6, ICC 6579, ICC 8950 and ICC 10945 were highly stable for seed yield across the environments.
