Abstract
The present investigation was carried out to understand the effect of salinity stress on different morphological traits in rice at reproductive stage. A totalof 150 rice genotypes including 10 checks were evaluated under nonstress (ECe ~ 1.2 dS/m) and saline stress (ECe ~ 10 dS/m) in micro plot in two replications with Randomized Block Design. From the investigation, it was observed that yield declined because of decreases in panicle length, filled grain number, and unfilled grain under saline stress condition. The genotypes (CSR-1148-31, CSR-CPB-39, CSR-1148-130, and CSR-C27SM-22) were considered as salt tolerant with high yielding. Thus, these genotypes could be valuable for breeding program indevelopment of rice varieties and could be used for commercial cultivation.
