Available variability in cowpea is meagre due to its breeding behaviour. However, variability is the prerequisite for improvement of yield levels in cowpea. In present study an experiment was conducted to estimate genetic variability, heritability and genetic advance expressed as per cent of mean, an investigation was carried out with two F2 populations of MFC-09-1 × PL-3 and MFC-09-12 × UPC-8705 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. 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 populations. Good number of superior segregants was isolated for seed and green fodder yield related traits in both the F2 populations.
