Detection of presence of non-allelic interaction for yield and yield contributing characters in okra Abelmoschus esculentus L. Moench

Abstract

The experimental material comprised of six generations (P1, P2, F1, F2, BC1 and BC2) through generation mean analysis of six crosses with different parents. The generations were analysed during kharif 2019 in Randomized Block Design with randomization of generations within each cross in two replications. The traits were studied number of ridges per pod, number of seeds per pod, weight of 10 seeds (g), weight of 100 seeds (g). The scaling test indicated the presence of non-allelic interaction in all the crosses. In all the crosses PBNOK-6 x Pusa Makhmali was observed superior in most of the characters. In the most of the crosses the dominance (h) component was observed to be important in the inheritance of characters like weight of 10 seeds, weight of 100 seeds and additive x dominance (j) interaction was showed importance in number of ridges per pod, number of seeds per pod. Most of the characters showed complementary type of gene action. Complementary type of gene action play role in transfer inheritance characters. Some characters showed duplicate type of epistasis. Its play important role for transgressive selection of the characters.
