Abstract: The present investigation was carried out to estimate genetic variability among 27 genotypes of vegetable cowpea for fifteen characters comprised of pod yield and its contributing characters. These genotypes were planted in Randomized Block Design with three replications during Kharif, 2016 -17 at Horticulture Farm, S.K.N. College of Agriculture, Jobner. Based on mean values with respect to characters, the highest yielder genotype is Kashi Nidhi followed by Kashi Kanchan, Kashi Shaymal and Kashi Unnati per plant basis. These genotypes might be utilized as potent parents in a breeding programme. Analysis of variance revealed highly significant differences among the genotypes for all the characters. The highest GCV and PCV were recorded for plant height at 45 days followed by pod length. High heritability along with high genetic gain was observed for plant height at 45 days, nitrogen content in pod, protein content in pod, pod length, number of pods per cluster, number of primary branches per plant, days to first pickings, pod yield quintal per hectare, pod yield per plant, number of clusters per plant, days to 50 per cent flowering and leaf area. Therefore, these characters can aid in selection programme.
