Abstract: The experiment was conducted at Main Experimental Station, Department of Vegetable Science, Narendra Deva University of Agriculture and Technology, Kumarganj, Ayodhya during Kharif, 2016 in Randomized Complete Block Design with three replications using thirty genotypes of okra collected from different sources to study the extent of variability, heritability and genetic advance in per cent of mean for different quantitative traits. The analysis of variance for the design of experiment indicated highly significant differences among the genotypes for all the characters. Based on mean performance of genotypes NDO-33 (212.16) followed by NDO-31 (199.03), NDO-24 (195.50), NDO- 35 (190.20) and NDO-17 (189.23) were found as five most promising genotypes for fruits yield per plant. High magnitude PCV were observed in case of unmarketable fruit yield per plant (31.34) followed by marketable fruit yield per plant (21.46), number of fruits per plant (20.78), total fruit yield per plant (19.70) and branches per plant (14.60). Moderate PCV along with GCV were recorded for number of branches per plant (14.60, 9.57) followed by fruit circumference (12.86, 8.11), fruit length (12.26, 8.34), average fruit weight (10.23, 9.42) and plant height (10.88, 9.00). High heritability were estimated for total fruit yield per plant (93.82) followed by unmarketable fruit yield per plant (87.68), average fruit weight (84.86), days to 50% flowering (84.54) and marketable fruit yield per plant (81.13). High heritability coupled with high genetic advance were estimated for total fruit yield per plant (93.82, 38.08) followed by unmarketable fruit yield per plant (87.68, 56.60) and marketable fruit yield per plant (81.13, 35.87) which indicating opportunity for high selection response.
