Abstract:

Selection of suitable breeding methodologies in bringing desirable improvement in crop plant require the complete knowledge about the nature of gene action involved in the inheritance of quantitative and quality traits. Gene action for fruit yield and its components studied using 6×6 full 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 traits. 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 except for of leaves at 45 and 90 DAS, average fruit weight, fruit length, and fruit diameter. The estimates of narrow sense heritability were high only for the crude fibre content.
