Abstract:
Seventeen genotypes including check SUB-106 and three replication were taken in the investigation and pots were arranges in the complete randomize design (CRD) for the study. After 25 days of sowing plant were submerged in outdoor flooded one meter deep water tank for 14 days and water level maintain the one meter from ground surface of the tank. One set of plants were kept outside as non-submerged control set. Before submergence at 25 DAS and after 14 days of submergence period, the data were taken on growth parameters like Dry weight of radical, Dry weight of plumule, Number of plants at 25 and 40 DAS, Dry weight (g) per plant at 25 and 40 DAS and biochemical parameters like α-amylase enzyme activity in germinated seed at 7 DAG, total chlorophyll content and starch content in the leaves were recorded. Among the seventeen genotypes before submergence and after de-submergence significant genotypic variations were observed and significant reduction/increase in number of plants per pots, dry weight of radical, dry weight of plumule, dry weight per plant and biochemical parameters like α-amylase enzyme activity in germinated seed at 7 DAG, total chlorophyll content and starch content in the leaves were recorded. The survival percentage, number of plant per pot and dry weight per plant, chlorophyll and starch data basis genotype SUB-102 is found better for submergence tolerant in comparison of check SUB- 106 and SUB-113 is also moderate tolerant.
