The present investigation was conducted to known the nature and magnitude of genetic variability among the 150 F2 segregating population along with their parents and standard check. The experiment was laid out at ZAHRS, Shivamogga, during Kharif 2019. The recorded data was statistically analyzed by using randomized block augmented design. The analysis of variance showed significant difference in the experimental material used for all the different characters under study. Results also revealed that the estimates of PCV were higher than the GCV for all traits. The highest PCV and GCV were recorded for trait viz., yield per vine, number of branches per vine, days to first male flower appearance, fruit diameter, number of nodes at which first male flower appear and rind thickness. The high heritability with high genetic advance as percent of mean was observed for the traits viz., number of seeds per fruit, days to first harvest, diameter of vine, days to first male flower appear, number of leaves per vine, fruit diameter, days to first female flower appear, fruit length, number of branches per vine, vine length and number of fruits per vine. Hence, genotypes are selected based on the phenotypic performance of these traits would be more rewarding for selection
