The present investigation was carried out to the heterosis, inbreeding depression and residual heterosis for yield and yield attributing traits in segregating generations of okra (Abelmoschus esculentus L.). An experimental material comprised F2 and F3 segregation generation, two parents, F1 and one standard check (Parbhani kranti) were evaluated in a randomized block design with three replications during kharif 2017. The perusal of data revealed that the characters for days to first flowering, plant height, internodal length and fruit weight in this cross show significant heterosis in desirable direction over standard check. For traits plant height, internodal length, number of branches per plant, fruit diameter and fruit weight positively high significant heterosis over better parent. Residual heterobeltiosis for the F3 generation the traits plant height, number of nodes per plant and length of fruit negatively and fruit diameter positively significant over better parent. Whereas days to first flowering, plant height, number of nodes per plant and length of fruit negatively significant over check Parbhani kranti. The inbreeding depression in F2 generation was highest significant for the character plant height, number of branches per plant, number of nodes per plant and fruit yield per plant. Whereas, F3 generation number of branches per plant show high and negatively significant.
