Studies on the Expression of Heterosis in Interspecific Hybrids of Sesame (Sesamum indicum L.)

The present study was undertaken to develop superior hybrids for yield and its component traits in Sesamum indicum L. through interspecific hybridization by utilizing S. malabaricum as one of the parents. Direct reciprocal crosses were attempted using eight cultivated varieties malabaricum, which evaluated a total fifteen hybrids. Highly significant positive heterosis observed few vegetative traits. For single plant yield, number seeds per capsule, 100 seed weight, highly negative observed. hybrid SVPR 1 x had expressed significantly relative days first flowering, maturity, height. cross TMV 3 shown primary secondary branches capsules on main stem branches.
