Abstract:

This investigation on line X tester cross of 8 lines and 3 testers and their 24 crosses in Cowpea indicated the preponderance of non-additive gene action for all characters under study. The linesCPD-83 and tester GS- 9240were good general combiners for grain yield per plant and most of yield contributing characters. High SCA effect observed in the hybrids viz. H 22 (CPD -83 X PCP-97102), H 11 (CPD -31 X GS-9240) and H 2 (CPD -219 X GS-9240) for grain yield per plant (g). The characters pod length (46.61%), number of grains per pod (40.36%), and harvest index (33.21%) exhibits high heritability while remaining all characters except plant height exhibits moderate heritability.
