Abstract: Ten local biroin rice varieties were evaluated with a view to find out variability and genetic association for grain yield and its component characters. All the characters tested were showed significant variation among the varieties. The highest genetic variability was obtained in flag leaf area and filled grains/panicle. High heritability associated with high genetic advance was observed in filled grains/panicle, 1000-grain weight flag leaf area, harvest index and grain yield. Genotypic correlation coefficients were higher than the corresponding phenotypic correlation coefficients in most of the cases. Plant height, days to maturity and filled grains/panicle showed significant positive correlation with grain yield. Path analysis revealed that plant height, days to maturity, 1000-grain weight and chlorophyll content had positive and highest direct effect on grain yields. Moreover, panicle length had highest indirect effect on grain yield through plant height and filled grains/panicle had positive and higher indirect effect on grain yield through days to maturity, panicles per hill and panicle length.
