Different wheat varieties were grown under the normal irrigated and very late planting situations, under wheat improvement project JNKVV, Jabalpur, Madhya Pradesh in order to expose plants to different level of temperature and water regime, since the two situation differ in the total amount of rainfall and number of irrigation supplied during the growing season. Plants were suffered from the terminal heat stress as well as drought stress in the very late sown condition. Since genotype, PBW-343/CDWR-9563-1 showed better performance under both planting situations on basis of grain yield. MP-3349/MP-3222, HD-2864, and GW-366 were the genotypes showed high amount of chlorophyll content, higher relative water content and coolest canopy under both planting situations. All measured parameter, chlorophyll content, relative water content and canopy temperature are good physiological indices of drought and heat stress tolerance and can be used for the enhancement of drought and heat tolerance genotypes in wheat.
