Wheat is the one of the most important cereal crop in the world. High temperature stress is a common environmental phenomena encounter by wheat throughout the world. Wheat is sensitive to high temperature; increase in temperature is a severe threat to wheat production and quality loss, particularly when it occurs during reproductive and grain-filling phases. Keeping in view a field experiment was conducted to evaluate twenty wheat genotypes (ten heat tolerant and ten heat susceptible) for various physiological, biochemical traits at anthesis, seven days after anthesis and identify promising wheat genotypes under terminal high temperature condition. High temperature significantly influenced physiological, biochemical, yield and yield attributes at anthesis and 14 days after anthesis (DAA) in both heat susceptible and heat tolerant genotypes. Decrease in carotenoids content and cell membrane stability (CMS) was least in heat tolerant genotype i.e., WH 730 (9.4%) and WH 1021 (10.5 %) respectively. WH 1021 showed high cell membrane stability (CMS), carotenoids content at anthesis and 7DAA. WH 1021 also, retained highest biomass, grain yield and 1000 grain weight. In present investigation heat tolerant genotype WH 1021 was found to be the most suitable one terminal high temperature condition on the basis of the overall picture of physiological, biochemical and yield traits studied.
