Abstract:
The present investigation was carried out to access genetic variability, heritability and genetic advance with a set of forty two genotypes of cowpea. A high phenotypic coefficient of variation (PCV) and genotypic coefficient of variation (GCV) estimates were recorded for number of pods per plant, seed yield per plant, 100-seed weight, plant height and number of clusters per plant. High heritability coupled with high genetic advance as per cent of mean (GAM) was observed for number of pods per plant, seed yield per plant, 100-seed weight, number of clusters per plant. This may be attributed to the preponderance of additive gene action and passes high selective value and thus, selection pressure could profitably be applied on these characters for their rationale improvement. Hence, these characters may be simultaneously selected for developing better quality high yielding genotypes of cowpea.
