Under terminal heat stress, the relatively more tolerant genotype exhibited lesser reduction in dry matter partitioning to the developing seeds. This happended due to a lesser reduction in yield components like grain number, 1000 grain weight, grain yield per pot during critical period i.e. II and III week of grain filling. As regards the assimilate supply is concerned, the stem reserve mobilisation was also found to be more in relatively tolerant genotype during the critical phase of grain filling.
