Abstract:
The nature and magnitude of gene action was analyzed by six generation mean for yield and percent incidence of fruit borer and yellow vein mosaic virus (YVMV) contributing characters in six inter varietals crosses of okra. The results revealed that both additive (d) and dominance (h) gene effects were significant for majority of the traits in all the six crosses studied, however the magnitude of dominance (h) gene effects was much higher than the additive (d) effects in all the crosses for majority of the traits which indicated pre-dominant role of dominance (h) gene effects in the inheritance of yield and its related traits. Study indicated that dominance gene effects for yield and yield contributing characters were of prime importance. All the characters recorded significant additive (d) and dominance (h) gene effect but the magnitude of dominance (h) gene effect was higher. Among the non-allelic interactions, additive x additive (i) and dominance x dominance (l) were found significant, the opposite sign of dominance (h) and dominance x dominance interaction (l) indicated that both the characters are controlled by duplicate type of epistasis. So, further improvement could be expected through bi-parental mating or reciprocal recurrent selection.
