The current study examined the nature of genetic variability, heritability, and genetic advance in 5 genotypes of bottle gourd in Table 1 and Table 2. For all of the traits studied, the results revealed highly significant differences between genotypes. This suggested that there was enough variance in all of the traits to allow for effective selection in the material under examination. GCV and PCV estimates were high for the length of vine, number of branches per vine, number of nodes per plant, number of female flowers per vine, number of fruits per vine, fruit yield per vine, fruit yield per plot and fruit yield per hectare. Most of the characters studied had higher heritability estimates, However, for characteristics such as length of vine, number of branches per vine, number of nodes per plant, number of female flowers per vine, number of fruits per vine, fruit yield per vine, fruit yield per plot and fruit yield per hectare, considerable genetic advance as a percentage of mean was seen. While the number of branches per vine, node at which first female flower occur, days required for occurrence of first female flower, number of female flowers per vine, number of fruits per vine, fruit yield per vine and fruit yield per plot were showed low genetic advance. Presented in the Table 1 and Table 2.

More variability exists in the content for all of the characters, which can be employed in the future by simple selection. According to the findings of this study, the number of female flowers per vine, number of fruits per vine and fruit yield per vine are the primary yield contributing features in bottle gourd. As a result, due to the importance of these features in developing the criterion in the selection process to evolve high yielding genotypes of bottle gourd.
