The present investigation was conducted at College Farm, N. M. College of Agriculture, Navsari Agricultural University, Navsari during kharif - 2016 with a view to study the heterosis and inbreeding depression in five crosses (each having P1, P2, F1, F2, BC1 and BC2 generations) of cow pea through a compact family block design with three replications. The analysis of variance between crosses revealed that the mean square due to crosses were significant for all the characters except for chlorophyll content. The F1s deviated positively from their batter parent in majority of crosses, indicating importance of heterosis. The magnitude of heterosis were significantly higher for seed yield and its contributing traits i.e. number of pods per plant, number of seeds per pod and 100 seed weight. The crosses which manifested high heterosis for yield and its components also showed high inbreeding depression. Highest heterosis with the lowest inbreeding depression was observed in cross Waghi local x W-203-1 followed by KM-5 x GC-3 and Pant lobia-2 x GC-3, these can further be exploited for commercial point of view.
