Combining Ability Studies through Diallele Analysis for Yield and its Component Traits in Sesame (Sesamum indicum L.)
Journal Title: International Journal of Agriculture Innovations and Research - Year 2018, Vol 7, Issue 1
Abstract
Diallel analysis, involving eight parents without reciprocals was carried out in F2 generation of sesame for twelve important yield components. The analysis of variance indicated that though additive and non additive gene effects are important for these characters, there was specific role of additive gene control for plant height and number of capsules on main stem, for the remaining characters the non additive gene control was recorded. The GCA effects indicated that the parent Co-1 was good general combiner for seed yield per plant, plant height, number of capsules per plant, number of capsules on main stem and number of capsules on primary branches, ACV2 for early flowering and DT 9-10-2-25 for number of secondary and primary branches. Among the 28 hybrids studied the crosses Co-1 x AVT26, Co-1 x DT 9-10-2-25, TNAU 20 x AVT 26, Co-1 x TMV6 and TNAU 20 x TMV26 were the potential as they had high significant SCA effects with desirable per se mean for 3 to 4 yield components characters. Desirable transgressive segregants are expected from these crosses.
