Abstract:
The present investigation was conducted with a view of analyzing the heritability, genotypic coefficient of variation, phenotypic coefficient of variation genetic advance and genetic gain on 19 genotypes of okra out at Vegetable Research Farm, Department of Horticulture, Institute of Agricultural Sciences, Banaras Hindu University, Varanasi during the summer season of 2018. High heritability was observed for all the characters whereas high PCV and GCV was observed in number of primary branches per plant, internodal length, fruit yield per plant, fruit length, fruit diameter, seed yield and seed index. While moderate value of PCV and GCV was seen, plant height, node at which 1st flower appears, number of nodes per plant, number of fruits per plant, average fruit weight, number of seeds per fruit and moderate PCV was only found in seed weight per fruit and days to 50% flowering. Whereas GCV and PCV was found low only in days to edible maturity and low GCV was registered in seed weight per fruit and days to 50% flowering. In case of genetics advance, highest values was observed in plant height, number of primary branches per plant, fruit yield per plant and seed yield per plant. Moderate genetic advance was registered in number of seeds per fruit and low genetic advance was showed in days to 50% flowering, node at which 1st flower appears, internodal length, number of nodes per plant, number of fruits per plant, fruit length, fruit diameter, average fruit weight, seed weight per fruit, days to edible maturity and seed index.
