Wheat being a temperature sensitive crop, its development and productivity respond significantly to dates of sowing. Result revealed that maximum & minimum temperature and solar radiation will be increased in rabi crop growing season in 2030-31, 2050-51 and 2070-71 while rainfall will be decrease during wheat growing season at both Upper and Trans Gangetic plain. Second date of sowing (15 Nov) showed maximum growing yield of HD 3086 at Upper Gangetic plains while first date of sowing showed maximum grain yield of PBW 343 at Trans Gangetic plain region. Based on sensitivity analysis it was observed that taken by emergence, anthesis, physiological maturity and grain yield of HD 3086 will be decrease in the future climatic conditions i.e. 2030-31, 2050-51 and 2070-71, respectively. Highest reduction will be occurred in 2070-71 followed by 2050-51 and 2030-31.
