Abstract:
Present experiment was taken up entitled “study the effect of high temperature stress on pollen viability, stigma exertion, sterility in rice” at Indian Institute of Rice Research, Rajendranagar, Hyderabad during Kharif, 2012-2013 and 2013-2014 in split-plot design with treatments (Normal temperature and temperature stress) as main plot treatments and 22 genotypes as sub-plot treatments. The high temperature treatment was imposed by covering the one set of genotypes with polyethylene sheet to raise the temperature and allowed to grow inside the enclosure from panicle initiation until physiological maturity. From the studies, it is concluded that superior performance in terms, reproductive traits such as pollen viability, stigma exertion were significantly affected by high temperature stress conditions.
