Assessment of genetic architecture of some economic traits in okra (Abelmoschus esculentus (L.) Moench) through generation mean analysis

The nature and magnitude of gene action was analysed using six generations viz., P1, P2, F1, F2, BC1 and BC2 for yield and yield contributing characters in four inter varietal crosses of okra. The scaling and joint scaling tests indicated the presence of epistatic gene effect for all the characters in four crosses. Duplicate epistasis was predominant in most of the yield and yield attributing characters in all the four crosses except number of fruits per plant, which showed complimentary epistasis. Study of gene action revealed that both additive and non-additive components of genetic variations were found important for the inheritance of fruit yield and its attributes. | Assessment of genetic architecture of some economic traits in okra Abelmoschus esculentus L.
