The present investigation was conducted during two consecutive years 2012 and 2013 to understand the possible mechanism of salinity tolerance to wheat under water logging condition. Fifteen genotypes of wheat were screened on the basis of survival of the seedling kept under water logging for 10 days in sodic field. Five centimeter deep water logging was created for ten days at 30-day stage of seedling by providing irrigation and at 40 DAS water was drained from field. The results revealed that water logging treatment reduced chlorophyll content in leaves in all the genotypes. Sodium and iron content increased in leaves under water logged condition in all the varieties while reverse trend was observed under non waterlogged condition. Antioxidant enzymes (superoxide dismutase, catalase and peroxidase) and nitrate reductase activity increased under waterlogged condition in all the varieties as compared to non waterlogged but drastic increase was noted in case of tolerant than susceptible varieties.
