ABSTRACT
A study involving 36 genotypes comprising 28 hybrids and 8 parents of pigeon pea revealed
higher magnitude of sca variance over gca variance for all the traits which indicated preponderance
of non-additive gene action. The parents ICPL-87, GT-1 and ICPL-87119 were good general
combiners for seed yield and its two or more component traits. Fifteen out of 28 hybrids showed
significant positive sca effects for seed yield and its two or more component traits.
