Abstract:

The estimates of components of genetic variation in okra revealed that additive component ( ) was significant for all traits i.e. days to first flowering, days to first pod picking, plant height, number of nodes, internodal length, pod length, pod girth, avg. pod weight, number of pods per plant, pod yield per plant (g), number of seeds per pod, 100 seed weight (g), seed yield per plant (g) and pod yield (t/ha). Both the components of dominance variance ( and ) were significant for all the traits and were much higher in magnitude than the corresponding additive components ( ), thus revealing the importance of non-additive gene action in the inheritance of traits under study. Net dominance effect ( ) was found to be positive and significant for all traits except 100 seed weight in all the environments as well as in data pooled over environments. The value was positive and significant for days to first flowering, days to first fruit picking, number of nodes, internodal distance, plant height, pod length, pod girth, number of pods per plant, pod yield per plant and seed yield per plant indicating the role of dominant alleles towards dominance variance and non significant for average pod weight, number of seeds per pod, 100 seed weight and pod yield revealing the role of recessive alleles towards dominance deviation.
