Due to increasing temperature drastic reduction in wheat yield was observed. In late sown condition plants face high temperature stress. In the present study the effect of late sown/stressed condition on yield and yield related attributes was investigated in comparison to timely sown/non-stressed condition at Punjab Agricultural University, Ludhiana. The experiment comprised of two sowing dates non-stressed/timely sown and stressed/late sown . Performance of twenty-five genotypes was evaluated under both sowing conditions. Results revealed that significant variation for number of productive tillers, Biomass/net plot, grain weight/net plot, thousand grain weight, grain weight and grain number per spike and yield was observed between non-stressed and stressed condition. The contents were higher in case of non-stressed condition. There was no influence of stressed condition on crop emergence. Genotypes DBW 14, PBW 820 and WH 1239 perform better under timely sown conditions. In late sown condition high temperature at reproductive stage is one of the major factor for yield loss. In stressed condition number of productive tillers decrease by 12.97%, grain weight by 22.32% and yield by 22.46%. Whereas, genotypes PBW 796 and PBW 821 perform better in stressed condition. Among all the genotypes PBW 821 gives superior results for yield and yield related parameters in stress condition.
