Abstract:
The effect of salinity on morphological characters of some rice genotypes, i.e., Pant Basmati1, Pant Sugandh21, Pant Dhan 24, and CSR30 were analysed by a two factor Complete Randomized Design with three replications. The different morphological characters, such as plant height, total number of tillers, leaf number, and total dry matter (TDM), were analysed under control and 50,100 and 150 mM NaCl conditions. Results showed that plant height, total tillers, and total dry matter were significantly decreases with increasing salinity. The highest reduction in plant height, tiller number, leaf number, and total dry matter was found in Pant Basmati1, followed by Pant Sugandh21, Pant Dhan 24. Whereas the reduction rate was less in CSR 30 as compared to other genotypes. Overall results indicates that the Pant Basmati1 is more sensitive to salinity as compare to the other whereas CSR30 showed better performance.
