Abstract: An Experiment was conducted with rice genotypes Swarna Sub1 and Nagina 22 with its mapping population in pot during kharif season 2017 at the pond of department of crop physiology in Narendra Deva University of Agriculture and Technology, Kumarganj, Faizabad (U.P). Submergence treatment was given for 14 days at vegetative stage. The screening of rice genotypes was done on the basis of Shoot elongation, Survival percentage, estimation of catalase, peroxidase and chlorophyll content. The rice genotypes Swarna Sub1 showed high percent increase in catalase and peroxidase whereas in case of chlorophyll content Swarna Sub1 shower higher percent reduction in Nagina 22. Therefore, on the basis of their parents some mapping population showed less and higher percent reduction and also showed best tolerance in compare to other population.
