In the present investigation 50 rice genotypes were used to study character association, path analysis and variability. The studies of variance among 50 genotypes for ten characters revealed that the genotypes differed significantly for all the characters under study. PCV was recorded highest for plant height (22.93) followed by effective tillers/plant (21.60) and biomass per plant (18.35). Low magnitude of PCV was exhibited by harvest index (9.28) followed by 1000 grain weight (9.99) and days to maturity (10.16). GCV was also high for plant height (22.90) followed by biomass (16.96) and grain yield per plant (16.77). Whereas, low magnitude of GCV was exhibited by harvest index (6.99) followed by 1000 grain weight (9.52) and days to maturity (10.10). The highest heritability was found in days to 50% flowering, days to maturity and plant height (99%) followed by spikelet fertility (95%) and panicle length (93%). Lowest heritability was observed in effective tillers/plant (55%) followed by harvest index (56%). Genetic advance as percent of mean (5%) was realized highest for plant height (47.12) followed by biomass (32.29) and grain yield per plant (32.10). Lowest value was observed in harvest index (10.85) followed by 1000 grain weight (18.69) and days to maturity (20.70).
