Heat is one of the major factors that considerably limit rice production. Here we report a novel temperature induction response (TIR) technique which was standardized for Rice crop. By adapting TIR technique 74 genotypes were screened for thermo tolerance. Out of 74 genotypes, 14 genotypes exhibited thermo tolerance due to induced high temperature. These geno-types have intrinsic heat tolerance and they can be explored as donor source in breeding program aimed for global warming.
