Information on genetic variance is derived from data on 7 yield components in parents Govind (early) and Jaya (medium), their F1 hybrids and crosses of the F1 hybrids with 7 other varieties. Epistasis contributed significantly to all traits. Additive effects were the main source of variation for plant height, days to flowering, 1000-grain weight and grain yield/plant, while dominance effects were important for 1000-grain weight, grain weight/panicle and grain yield/plant.
