Combining Ability Analysis in Medium Duration CGMS Based Hybrid Pigeonpea (Cajanus cajan (L.) Millsp.)
2013
Forty eight hybrids were developed by using six A2 cytoplasm based CGMS lines and eight diverse restorers and their hybrids were evaluated with an objective to estimate the nature of gene action for yield and yield contributing characters. Predominance of non additive gene action was observed for almost all the characters including seed yield except plant height which was under the influence of additive gene action. None of the parents exhibit significant gca effects for all the characters under study, however among the lines AKCMS 10A, AKCMS 13A and AKCMS 09A and among the testers AKPR 8, AKPR 359 and AKPR 292 were identified as potential parents as they exhibited significant gca effects for most of the important traits. Among the hybrid combinations AKCMS 09A x AKPR 8, AKCMS 10A x ICPR 2740, AKCMS 11Ax AKPR 319, AKCMS 09A x AKPR 374 and AKCMS 06A x AKPR 359 might be exploited for the improvement of respective traits as found to possess desirable genes for most of the important characters including seed yield.
