Morpho-physiological traits of different rice varieties grown under water logged and submerged condition

An experiment was conducted to evaluate morpho-physiological traits of different rice varieties grown under water logged and submerged condition during Kharif- 2012, showed maximum number of inter-node (more than 3cm) in stem (6.85), adventitious root (4.23), plant height at 90 days (135.53 cm) and (152.33 cm) at 150 days, number of tillers (9.20) at 120 days, effective tillers/hill (8.74), LAI (4.91), LAR (58.78 cm2 /g), relative growth rate (38.93 mg/g/day), LWR (0.30 g/g), crop growth rate (11.66 mg/m2 /day), NAR (40.95 mg/dm2 /day, shoot dry matter (1145.0 g/m2 ), panicle length (27.26 cm), ripened grain/panicle (203.33) and 1000 seed weight (24.58g) in Varsadhan. This suggests the possibility of Varsadhan as water logged and submergence tolerance due to better performance of physiological traits. So this variety might be adopted in the larger area where the flood was a major problem.
