Abstract

The performance of 36 hybrids of Sesamum i,.dicum L. involving cultivars of diverse origin was·studied to estimate heterosis for seed yield and other component characters. The midparental (MP) and better parent (BP) heterosis for seed yield ranged from-91.9 to 76.3% and -47.1 to 72.5%, respectively. Out of 36,19 hybrids showed significant positive heterosis over the correspondingBP for seed yield. Significantheterosis for all the other components (except for plant height and per cent oil), the highest magnitudes being from seed yield on secondaries, seed yield on primaries and seed yield on main stem was also observed, indicating their contribution towards seed yield heterosis. Crosses, R 84-4-2 x VS 16 and RT S4 x VS 16, involving high general combining parents, manifested very high and significant heterosis and sea effects for seed yield, and are useful for exploiting hybrid vigour.
