The experiment was conducted at Plant Physiology Division in Bangladesh Rice Research Institute to identify best tolerant genotypes based on survival and recovery. A total of 76 genotypes (Acc. No. 24, 82, 83, 84, 85, 86, 88, 89, 90, 91, 92, 93, 95, 97, 99, 10, 103, 108, 109, 110, 113, 114, 119, 120, 121, 123, 127, 128, 130, 131, 135, 136, 143, 146, 165, 166, 171, 173, 217, 230, 237, 248, 250, 252, 412, 416, 440, 444, 449, 450, 451, 453, 454, 456, 457, 458, 459, 460, 461, 462, 463, 465, 466, 407, 1838, 3950, 4206, 4217, 4218, 4398, 4399, 4548, 4578, 4096, 4398, 4399, FR13A (Res. Check), BR5 (Sus. Check) were tested in this experiment. Fourteen days old seedling was transplanted in the Plant Physiology submergence tank. The spacing was 20 cm X 20 cm and 2 rows were maintained for each genotype. At 14 days after transplanting, the crop was allowed to complete submergence maintaining 75 cm water depth for 14 days. During submergence period, the water of the tank was made turbid twice daily and the light intensity in upper level (normal), mid-level (30 cm below the water surface) and lower level (75 cm below the water surface) of the tank water were measured through light meter (LI-250). The water pH and temperature were also measured and recorded. At 14 days after submergence, the water drained out from the submergence tank. The survival data was taken at 5 days after de-submergence. Survival scoring was done by SES. Recovery status was also evaluated 30 days of de-submergence. Tolerant check FR13A survived successfully, survivability was 100% but susceptible check BR5 didn’t survive well and the survivability was 17%. Among the tested genotypes, 4 genotypes were found non-elongating type and rests of the genotypes were found elongating type. The non-elongating type genotypes namely Acc.1838, Acc.4206, Acc.4399 and Acc.4096 were also identified as tolerant to 14 days of complete submergence having good survivability and excellent recovery. From the results 4 genotypes should be considered for further investigation to get donor materials for crossing.
