Line x tester analysis reveals non-additive gene action for pod yield in groundnut varieties, indicating breeding possibilities.

High per se performance seen in the hybrids CO 3 x TKG 19 A and CO 3 x TAG 24 for pod yield, indicating potential for breeding.
Specific combining ability variances suggest non-additive gene action for pod number and pod yield in groundnut parents.
Desirable parents identified include CO 3, TNAU 359, COGn 4, and TAG 24, useful for breeding programs.
Crosses derived from high general combining ability parents may lead to high yielding segregants in future generations.

MANIVANNAN et al. (2008) studied this question.
