Abstract
The present study examined sixteen sponge gourd germplasms that were arranged in a Randomized Block design (RBD) with three replications in order to evaluation of genetic variability, heritability and genetic advance among the characters during the spring-summer (March–June) and rainy (July–October) seasons of 2019 at the Vegetable Research Farm of the College of Horticulture, Banda University of Agriculture and Technology, Banda. The parameters were observed for nineteen traits. Analysis of variance showed significant differences among genotype for all the traits. The results indicated to the growing environment had an impact on the characteristics' expression in addition to genetics when it came to apparent variety. In the spring, summer, and rainy season, estimates of the number of branches, fruit diameter and number of fruits per plant were made for high GCV & PCV, heritability, and genetic advance as a percentage of mean.
