Abstract: Gene action for fruit yield and its attributes in okra (Abelmoschus esculentus (L.) Moench) become evaluated through Hayman’s analysis (numerical and graphical) for 45 F1 cross combinations together with their 10 parents of okra in randomized complete block layout design with three replications. Furthermore, numerical analysis was accomplished for all traits via examining estimates D, H1, H2, h2, E and F along with their standard errors and numerous statistical ratios viz., (H1/D)½, (H2/4H1), KD/KR, h2/H2 and Heritability (ns). The estimation of variance because of additive (D) and dominance (H1) each were concerned in the inheritance of most of the traits studied with preponderance of non-additive gene actions for all the traits. These findings have been additionally confirmed through average degree of dominance (H1/D)1/2, which was more than one indicating over dominance for all the traits. The ratio, H2/4H1, close to 0.25 for days to picking advised nearly symmetrical distribution, while for rest of the traits it recorded asymmetrical distribution of positive and negative alleles for loci exhibiting dominance for the traits. Likewise, KD/KR ratio discovered excess proportion of dominant genes for plant height, number of branches per plant, internodal length, number of fruits per plant, fruit length, ten fruit weight, fruit yield per plant and per cent infestation of fruit borer, whereas for characters days to first flowering, days to first picking, fruit girth, days to last picking, number of picking and duration of harvest revealed excess of recessive genes. The estimates of narrow sense heritability had been in spectrum of very low to moderate for all the traits. Graphical analysis was defined for all the traits viz., days to first flowering, days to first picking, plant height (cm), number of branches per plant, internodal length (cm), number of fruits per plant, fruit length (cm), fruit diameter (cm), ten fruit weight (g), days to last picking, number of picking, fruit yield per plant (g), duration of harvest, per cent infestation of fruit borer and per cent YVMV incidence, showing significant deviation of regression coeeficient (b) from zero and all these traits recorded variable degrees of dominance ranging from partial dominance to over dominance. The parents had more diversity as their array points scattered in the course of the graph for all the traits.
