Climate change and its consequences have severely affected Nepalese agriculture. The higher temperature in the lower elevations of the tropical region as well as lower temperature in the higher elevations has adversely affected rice cultivation. Therefore, to evaluate the performance of different rice genotypes in central hills present experiment was carried out at Nepal Agricultural Research Council, Khumaltar, Lalitpur, Nepal in 2017 A.D. under irrigated main season rice system. Split Plot

The result showed that the temperature increments inside the chamber have not significantly influenced the yield of rice. Within 4 rice genotypes, Khumal 10 and Khumal 8 were found to produce significantly higher yield.
