The major abiotic stresses affecting chickpea production are high and low temperature, drought and salinity. In caseof extreme temperatures, chickpea is very sensitive during the reproductive phase of plant growth. A study was carried out toevaluate yield potentiality with 44 chickpea genotypes sown under three dates of sowing (41th, 44th and 48th SMW). Thepartitioning efficiency was significantly higher under 41st SMW (26.23 g plant-1) followed by 44th SMW (22.63 g plant-1).However, genotype JAKI 9218 recorded maximum total dry matter (31.61 g plant-1) compared to other genotypes. The podweight and seed number per plant recorded significantly higher under 44th SMW (21.76 g plant-1 and 52.23 plant-1) followedby 41st SMW (17.92 g plant-1 and 48.52 plant-1). Under 48th SMW, heat stress coincided with the reproductive stage resultedin reduced yield potential among genotypes. JAKI 9218 recorded maximum pod weight (27.64 g plant-1) followed byPA 1012334 (27.10 g plant-1). Further, test weight was significantly higher under 41st SMW (24.77 g) and harvest index under44th SMW (51.06). Under 41st standard week significantly higher seed yield was recorded (13.29 g plant-1) followed by44th standard week (11.95 g plant-1). Among the genotypes, JAKI-9218 recorded significantly higher seed yield (19.25 gplant-1) followed by GCP-107, PA-0102334, BGD 128, JG-11 and BGD-103 (18.59, 17.32, 15.75, 15.46 and 15.14 g plant-1, respectively). The experiment concluded that, genotypes JAKI-9218, GCP-107, PA-0102334, PHG-5, BGD 9920, BGD128, JG-11 and BGD-103 are most stable lines for heat tolerance and can be further used in breeding programme.
