Abstract: An experiment was conducted to evaluate the nature and magnitude of variability and character association among 36 rice genotypes. Increased temperature have high impact over salinity, hence the experimental materials were evaluated in randomized block design with three replications during 2017 under saline condition. The divergent studies showed the significant variation among the genotypes for all the characters studied. Correlation studies revealed that number of tillers/plant, 100 grain weight and grain length registered, positive correlation with grain yield per plant. Path analysis revealed that the traits grain breadth and grain L/B ratio had very high positive direct effect on grain yield. The traits days to first flowering, number of tillers per plant, Number of grains per panicle, grain breadth and grain L/B ratio had high positive direct effect on grain yield per plant.
