Abstract: The present investigation was carried out at Main Vegetable Research Station, Anand Agricultural University, Anand during Kharif 2017. The experimental material comprised of fifty diverse genotypes of okra collected from different eco-geographical area of the country. The genotypes were evaluated in Randomized Block Design (RBD) with three replications for fruit yield and yield attributing traits in okra. The analysis of variance revealed that mean sum of squares due to genotypes were found highly significant for all the traits under study indicated the existence of tremendous variability present in the experimental material for the characters. The high values of genotypic and phenotypic coefficients of variation were observed for number of branches per plant and chlorophyll content. The high heritability values coupled with high to moderate GCV and PCV as well as high genetic advance were exhibited by chlorophyll content, number of branches per plant, length of internodes, number of internodes on main stem, number of fruits per plant, plant height and fruit yield per plant suggested that preponderance of additive gene action. On the basis of per se performance, heritability and genetic advance as per cent of mean, the genotypes AOL-16-23, Parbhani Kranti, Arka Anamika, Kashi Vibhuti, AOL-10-22, Pusa Sawani, JOL-11-12, AOL-16-01 and AOL-16-03 can be used for development of pure line/ transgressive segregants, which would be effective for the improvement of these traits in okra.
