Heterosis, inbreeding depression and residual heterosis study in F2 and F3 segregating generations of okra (Abelmoschus esculentus (L.) moench)

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. | Heterosis inbreeding depression and residual heterosis study in F2 and F3 segregating generations of okra Abelmoschus esculentus L. moench
