Genetic variability, genotypic and phenotypic coefficient of variation, Heritability, genetic advance and Correlation analysis were undertaken for thirteen characters of bottle gourd obtained from the cross Pusa Samridhi x DBG-5 in F3 generation. High genotypic and phenotypic coefficient of variation and high heritability estimates associated with high values of genetic advance as a percent mean were observed for number of primary branches per vine, number of fruits per vine, yield per vine, average weight of fruit which indicated additive gene action for these characters, which could be improved by simple selection method. Yield per vine showed significant and high positive correlation both at phenotypic and the genotypic level in sex ratio, node at which first female flower appeared, average length of fruit, fruit diameter at pedicel, fruit diameter at center, fruit diameter at stylar end and number of fruits per vine. It is suggested that characters viz., node at which first female flower appeared, average length of fruit, fruit diameter at pedicel, fruit diameter at center, fruit diameter at stylar end and number of fruits per vine should be given priority for selecting high yielding genotypes.
