Abstract: The experiment comprised the study of heterosis, inbreeding depression and heritability in okra. The experimemental material consisting parents were crossed to produce five single cross hybrids (Parbhani Kranti x Shagun, Arka Anamika x PBN-1, Shagun x AKO-107, Akola bahar x PBN-13, AKO-107 x Pusa sawani) between different parents (Parbhani Kranti, Arka Anamika, Shagun, Akola Bahar, AKO-107, PBN-1, PBN-13, Pusa Sawani) along with check Ankur-40 (Hybrid). Material was evaluated during kharif 2013 in a randomized block design with randomization of generation replicated twice. The characters studied were plant height (cm), internodal length (cm), number of branches per plant, days to 50% flowering, fruit length (cm), fruit weight (g), fruit diameter (cm), number of fruit per plant, fruit yield per plant (g), fruit yield per ha. (q). the results were reveal that. The cross Parbhani kranti x Shagun is promising as it depicted heterotic performance for fruit yield per plant and other important yield contributing traits. Narrow sense heritability played an important role for fruit length. Inbreeding depression greatly occurred for fruit yield per plant, whereas, least inbreeding depression was observed for the traits plant height.
