The aim of the present study was to develop superior hybrids for yield and its yield components in cowpea (Vigna unguiculata L. Walp). A field experiment was undertaken to study heterosis in cowpea with objective to identifying superior hybrids for yield and yield components. The analysis was carried out with six lines and three testers by line x tester mating system to estimate the heterosis for yield and its attributes viz. days to 50 percent flowering, days to maturity, plant height at maturity, number of branches per plant, number of pods per plant, number of seeds per pod, pod length, 100 seed weight, harvesting index, seed yield per plant. High heterotic hybrids viz., UV-5 x Konkan Safed, UV-5 x Pusa Komal, Kashi Gauri x Konkan Safed, Kashi Nidhi x Konkan Safed and Kashi Gauri x Pusa Komal had high per se performance, heterobeltiosis and standard heterosis over check KBC-6 for yield and yield contributing traits. The highest value of heterobeltiosis and standard heterosis for UV-5 x Konkan Safed were 52.16 and 42.80 per cent respectively, for seed yield per plant.
