Abstract:

In order compute genetic variability, heritability and genetic advance expressed as per cent of mean, an investigation was carried out with 79 plants of F2 population of MFC-09-12 × PGCP-12 and 90 plants of F2population of MFC-08-14 × PL-3 in cowpea. Considerably high amount of variability was observed for the thirteen quantitative and qualitative characters under study. Environmental influence was minimum for the expression of most of the traits which is evident from narrow difference between phenotypic co-efficient of variation (PCV) and genotypic co-efficient of variation (GCV) estimates. In both the populations, heritability in broad sense was high for most of the traits coupled with high genetic advance as per cent over mean indicated presence of additive gene action for the characters. In both the F2populations, good numbers of superior segregants were isolated for seed and green fodder yield related traits.
