Description Pigeonpea is the major source of vegetable protein in
Indian diet. About 72.5 percent area and 62.5 production of
world’s pigeonpea is in India.Pigeonpea is the only food legume
where cytoplasmic-genic male sterility is being exploited for
commercial use of hybrids. The discovery of stable CMS system
and breeding of commercial hybrids in pigeonpea has become a
landmark in increasing the productivity of this crop. Keeping in
view the combining ability estimates were worked out through
Line x Tester analysis of 10 hybrids developed by crossing 2
lines (Males) with five cytoplasmic male sterile (CMS) lines
(Females) to know the genetic architecture of yield attributesDays
to maturity, branches plant1
, pods plant1
, seed yield, wilt
resistance and pollen fertility. Analysis of variance revealed
significant differences among genotypes, crosses, lines, testers
and Line x tester interactions for most of the traits.
Preponderance of non-additive gene action was realized by
higher values of specific combining ability compared to general
combining ability. The average degree of dominance were more
than unity (>1) and predictability ratio was less than unity (
