英文摘要	High temperature is one of the major limiting factors in wheat (Triticum aestivum L.) production in arid and semiarid regions of world. The crop experiences moderate to severe high temperature at most of its growth and physiological stages of growth. A glass house experiment was conducted to investigate the impact of high temperature on growth and productivity of wheat crop under different sowing regimes. Seventeen wheat genotypes were sown under two sowing dates with interval of thirty days in cemented bed filled with river sand. Results showed that high temperature stress due to late sowing has negatively influenced plant growth and yield by modulating physiological and biochemical attributes. Among the genotypes, NIA-AS-14-9, NIA-Sunder, Raskoh, TJ-83, Dani, Saher-2006 and SH-Salt-5B produced high plant biomass, productive tillers, number of grains and grain yield per plant under both sowing conditions. However, maximum relative water contents were observed in LU-26s while NIA-AS-14-10 showed better membrane stability and chlorophyll contents followed by NIA-Sarang, Kiran-95 and Dani under late sown conditions. NIA-Sunder, NIA-AS-14-10 and SRN-09111 had accumulated substantial proline contents but failed to produce significant amount of soluble sugars and glycine betaine (GB). These parameters showed higher accumulation for Dani, Saher-2006, Raskoh, Bathoor, TD-1 and Kiran-95 under high temperature stress. Overall results showed that genotypes SH-Salt-6, NRL-1236, NIA-Sarang, LU-26s and Dani were failed to cope effectively under high temperature stress conditions and illustrated poor performance.
