The present investigations were carried out with a view to know the extent of heterobeltiosis and standard heterosis in cowpea (Vigna unguiculata (L.) Walp.). Thirty hybrids were developed by adopting full diallel mating design. A set of thirty eight cowpea entries including six parents (NCK-15-9, NCK-15-10, NC-15-41, NC-15-42, NC-15-44, NC-15-45) thirty crosses and two check varieties, GC-3 and GDVC-2 evaluated at three locations viz.Navsari, Mangrol and Achhalia using randomized block design with three replications during Kharif-2017. The observations were recorded on parents and F1’s for fifteen quantitative traits and one quality traits viz. Days to 50 per cent flowering, plant height (cm), primary branches per plant, pods per plant, pod length (cm), seeds per pod, green seed weight (g), green pod yield per plant (g), straw yield per plant (g), shelling percentage (per cent) and protein content (per cent). Significant heterobeltiosis and standard heterosis over GC-3 and GDVC-2 were observed for green pod yield per plant and grain yield per plant. The cross NC-15-45 X NC-15-41, NCK-15-10 X NC-15-45, and NC-15-45 X NCK-15-10 recorded high heterotic values for green pod yield per plant and grain yield per plant along with high per se performance.
