Estimate of Genetic Variability and Heritability in Some Exotic Germplasm Lines in Kharif Rice (Oryza Sativa L.).

The high genotypic coefficient of variation, high heritability with high genetic advance as percent of mean was observed for grain yield per plant, total tillers per plant, productive tillers per plant and grains per panicle, whereas days to initiation of flowering, days to 50 % flowering and days to maturity had high heritability with low genetic adavance as per cent of mean.
