Abstract: This study was conducted to evaluate the submergence tolerance, response of peroxidase activity among 14 rice genotypes. Rice genotypes viz., Bad Dhana, Khawjii, Sambha, Lalkadhan, NDR9532, IR-72, Katy, NDR8610-2, Khaiyan, NDR9448, IR73707-43-3-23, NDR9930108, NDR9511, and Swarna sub-1 were evaluated for their peroxidase activity on fifteen days of submergence. Peroxidase activity was also recorded in normal as well as in submergence stress condition and maximum peroxidase activity under normal condition was noted in Bad Dhana and the minimum was noted in Sambha at all the stages of observation whereas, under stress condition maximum peroxidase activity was shown by Bad Dhana at 3rd day and minimum peroxidase activity was noted in Sambha at 1st day at all the stages of observation. In short peroxidase activities increased upto 3rd day their after declined trend were obtained. The results indicated that the submergence tolerance genotypes have higher peroxidase activity.
