Identification of heterotic hybrids and good combiner parents in leaf variants CGMS system in pigeonpea (Cajanus cajan L.)

Published on

Hybrids involving four diversified A2 cytoplasm based male
sterile (CMS) lines viz., oval leaf, sesamum leaf,
obcordifoliate leaf and small leaf, were selected and crossed
with twelve diverse fertility restorer lines of pigeon pea
(Cajanus cajan) and these lines with hybrids were evaluated
for the estimation of heterosis, GCA and SCA effects and
variances in Lines x Tester analysis. Among the four CMS
lines obcordifoliate leaf CMS line and three restorers AKPR-
178 (M), AKPR-364 and AKPR-192 were found good general
combiners for yield and yield contributing traits. Hybrids
viz., Obcordifoliate leaf × AKPR-178 (M), Obcordifoliate leaf
× AKPR-344 and Obcordifoliate leaf × AKPR-210 exhibited
highest significant economic heterosis and SCA effects
over two checks PKV-TARA and AKT-8811. Obcordifoliate
leaf was found best leaf type for hybrids.
