Genetic variability and the estimates of broad sense heritability observed in F2 population of Oryza sativa L. were significant for all the traits evaluated except for number of tillers per plant and panicle length. Heritability estimates were maximum for plant height, 100-seed weight, number of tillers per plant, spikelet density and panicle length but maximum genetic gain relative to the mean was expected for number of tillers per plant, plant height and spikelet density. Expected relative genetic advance was the function of heritability and coefficient of genotype variability, latter being more important.
