Abstract
The present study entitled “Character Association Studies in Okra (Abelmoschus esculentus L. Moench)” was carried out to assessvariability, heritability, genetic advance, correlation and path coefficientin okra. Fortyokra genotypes were sown in Randomized Complete Block Design replicated thrice during summer season, 2020-21 at Vegetable Research Farm-I, Division of Vegetable Science and Floriculture, FoA, Chatha, SKUAST-Jammu. The observations were recorded forseventeen characters namely, first flower node number, days taken to 50 % flowering, internodal distance (cm), days to first marketable fruit maturity, fruit length (cm), fruit girth (cm), fruit weight (g), number of ridges per fruit, number of seeds per fruit,number of fruits per plant, days to last marketable fruit maturity, plant height (cm), fruit yield/plot (g), fruit yield/ha (q), incidence of YVMV (%),incidence of fruit and shoot borer (%) and fruit hairiness. ANOVA revealed significant differences among all the characters studied except for number of ridges per fruit and incidence of YVMV. Highest Phenotypic Coefficient of Variation (PCV) and Genotypic Coefficient of Variation (GCV) were recorded for internodal distance followed by number of seeds per fruit, fruit yield/plot, plant height and number of fruits per plant. High heritability coupled with high genetic advance as percent of mean was exhibited by internodal distance, plant height, fruit yield/plot and number of fruits per plant.
Genotypic correlation coefficients were greater in magnitude than phenotypic ones. Fruit yield/ha had positive and significant correlation with number of fruits per plant, plant height, internodal distance, days to last marketable maturity, fruit weight, fruit girth and fruit length whereas negative and significant correlation with days to first marketable fruit maturity. Path analysis revealed that maximum positive direct effect towards fruit yield/ha was exerted by number of fruits per plant followed by plant height, fruit length, fruit girth and days to last marketable fruit maturity whereas days to first marketable fruit maturity followed by first flower node number and days taken to 50 % flowering exhibited negative direct effects on fruit yield/ha.
