Gene action in okra [Abelmoschus esculentus (L.) moench]

Gene action for yield and its components studied using 10 x 10 half diallel design in okra (Abelmoschus esculentus(L.) Moench). The genetic study revealed that estimation of variance due to additive (D) and dominance (H) both were involved in the inheritance of most of the traits studied with preponderance of non-additive gene actions for all the characters in both the generations. These findings were also confirmed by the values of average degree of dominance estimates (H₁/D)^1/2, which was found in the range of over dominance for all the traits in both the generations except for number of branches per plant in F₁generation. The estimates of narrow sense heritability were high only for fruit length in F₂ generation.
