ABSTRACT
The experiment was laid out in Randomized Complete Block Design (RCBD) with twenty four genotypes of okra [Abelmoschus esculentus (L.) Moench] and three replications. The PCV was higher than the GCV for all the characters. High estimates of heritability were obtained for the traits like yield per plot, fruit yield per ha, followed by fruit yield per plant, number of leaves per plant at 90 DAS and number of fruits per plant. The higher value of genetic advance as percent of mean was recorded for number of nodes to first flowering, number of fruits per plant, fruit yield per plot, fruit yield per hectare and fruit yield per plant. High heritability coupled with high genetic advance as percentage of mean for traits like fruit yield per plant, fruit yield per ha and number of fruits per plant suggested that they can be improved through direct selection.
High heritability supplemented with moderate genetic advances as percentage of mean was manifested by number of leaves per plant at 90 DAS. Path coefficient analysis revealed that number of fruits per plant had highest positive direct effect followed by fruit weight, number of nodes to first flowering, number of branches per plant at 90 DAS, length of internodes, number of leaves per plant at 90 DAS, plant height at 90 DAS and fruiting span are the most important character contributing towards fruit yield. Direct selection of fruit yield per plant, days to 50% flowering, days to first flowering, fruit length and days to first picking should be avoided instead of direct selection.
