Abstract:

The present investigation was carried out at Vegetable Experimental Farm-I, Division of Vegetable Science and Floriculture, FOA, Chatha, SKUAST-J, during the year 2018-2019. The experiment was laid out in Randomized Complete Block Design with three replications. The Analysis of Variance revealed significant differences among the genotypes for all the characters studied. The Phenotypic Coefficient of Variance (PCV) and Genotypic Coefficient of Variation (GCV) were high for number of fruits/vine and fruit yield/vine. High estimates of heritability were recorded for number of seeds/fruit, fruit yield/vine, average fruit weight, vine length, 1000 seed weight, fruit length, number of fruits/vine, fruit diameter, days to first harvest, days to 50 % flowering, node number at which first female flower appears, total soluble solids and days to first female flowering. High genetic gain as percentage of mean was observed for fruit yield/vine, number of fruits/vine, number of seeds/fruit, node number at which first female flower appears, 1000 seed weight, fruit yield/hectare, fruit length, average fruit weight and fruit diameter.The traits viz. number of fruits/vine, fruit yield/vine gave high heritability, genetic advance and GCV indicating that these are controlled by additive gene action and could be improved by direct selection. In general, genotypic correlations were higher in magnitude than phenotypic ones. Fruit yield/hectare showed negatively significant correlation with days to 50 % flowering while positive significant correlation with days to first harvest and number of fruits/vine. Maximum positive direct effect towards fruit yield/hectare was exerted by days to first female flowering followed by fruit yield/vine, total soluble solids, days to 50% flowering, number of seeds/fruit and number of fruits/vine.
