Abstract
The present investigation was undertaken to study tbe extent, of heterolis in single and threeway crosses in sorghum. Four male steriles, viz., CK-60A, 2219A, 36A and 120lA and their maintainers were intermated to produce twelve sterile single crosses. These 12 sterile crosses and 4 male steriles were crossed with five restorers, viz., 285, PD-3-1-1I. 168, 18-81- and C8-3S41, to produce sixty three way and twenty single crosses. The major contribution towards developmental and yield characters came from the male parents in single and threeway crosses. The performance of three way crosses was at per with single crosses. The grain yield per plant exhibited highest heterotic manifestation in both kinds of hybrids. The highest heterosis and heterobeltiosis was recorded by 1202AxCK60Bx)8-84 and 2219Ax36Bx 18-84 respectively. The females, both A and A xB, exhibited limited diversity for most of the characters. Further evaluation of most heterotic three way crosses for seed production and grain yield stability is suggested.
