Abstract

The studies were undertaken to investigate the response of rice cultivars under saline conditions.Salinity upto 10 dSmG 1 did not affect germination percentage in all varieties but the same level of salinity significantly affected plant height, fresh as well as dry weight of root and shoot and total number of tillers per plant.Germination percentage was not affected in NR1 and NR6 even at 20 dSmG 1 salinity level but BAS 370 was severely affected (70.00 percent) at this level of salinity.Regarding parameters studied, NR6 and IR6 showed adaptability under saline conditions.
