Moench)” were carried out at the Experimental Farm, Department of Vegetable Science, Dr. YS Parmar University of Horticulture and Forestry, Nauni, Solan (HP) during Kharif,2013 to evaluate diverse germplasm of okra. The experiment was laid out in a RCBD with three replications. Thirty six genotypes including check cultivars were evaluated for different horticultural traits. The observations were recorded on days to 50% flowering, first fruiting node, internodal length, plant height, fruit length, fruit diameter, fruit weight, number of fruits per plant, number of ridges per fruit, number of seeds per fruit, 1000 seed weight, fruit yieldper plant, fruit yield per hectare, incidence of fruit borer and severity of phytophthora blight. Analysis of variance showed significant differences among all the genotypes forall the characters studied. Genotypes LC-13, VRO-3, NS-29, LC-11, IC 58235 and IC 212267 gave higher yield and also performed better for other horticultural traitsunder mid hills conditions of Himachal Pradesh. The phenotypic and genotypic coefficients of variation were recorded high for internodal length and number of seeds per fruit. High heritability coupled with high geneticgain was observed for the characters like internodal length,number of fruits per plant and fruit yield per plant. Significant positive genotypic and phenotypic correlation of yield was found with number of fruits per plant, fruit weight and harvest duration, whereas, significant negativegenotypic and phenotypic correlations were found with days to 50% flowering, first fruiting node, internodal length and days to first harvest. Further, these genotypes were grouped into five divergent clusters and hybridization between cluster I and V gives maximum heterotic combinations.ennullThesis
