Global warming is unusually increasing the earth temperature over the past century at an average rate of 0.07􀔨 per
decade since 1880. The increased temperature exhibit greater impact on grain yield, approximately 5.18 million tons of rice
yields due to heat wave. Heat shock factors (HSF) has major role in regulating heat shock proteins which in turn responsible
for survival of plants in heat stress by refolding proteins, maintaining functional confirmation, aiding in host defence
mechanism. The aim of this research was to analyse phenological, biochemical changes and key genes highly expressed
during heat stress at flowering stage in rice. Expression analysis of nine HSF genes had given a differential expression under
heat stress as compared to controlled traits. This study suggested OsHSP26.7 as most responsive gene under heat stress and
rice line 159, RRF-127, GP-145-103 and Annada with heat tolerant adaptive mechanisms and better performance under high
temperatures and was found to be in correlation with the estimated biochemical traits. This can be taken as a base for heat
tolerance response of the crop, which may be useful for further validation studies of the candidate genes for heat tolerance in
the rice as well as other crop plants.
