The study was undertaken to estimate genetic variability parameters, correlation coefficients, direct and indirect effects for grain yield and its components in rice under aerobic condition. Productive tillers per plant, grain yield and number of grains per panicle recorded higher PCV, GCV and high heritability coupled with high genetic advance as per cent of mean, indicating the role of additive gene in expressing these traits. Panicle length, plant height and productive tillers per plant had the positive effect and significant positive association with grain yield per plant. Grain yield in rice under aerobic condition may be improved by selection of tall genotypes having long panicles with more number of productive tillers per plant.
