The present investigation analyzed the genetic variability, heritability, and genetic advance across five genotypes of bottle gourd, as delineated in Tables 1 and 2. The results indicated highly significant differences among the genotypes for all traits examined, suggesting substantial variance conducive to effective selection within the studied material. Estimates of genetic coefficient of variability (GCV) and phenotypic coefficient of variability (PCV) were notably high for several traits, including vine length, 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 traits exhibited elevated heritability estimates however, significant genetic advance as a percentage of the mean was particularly observed for vine length, number of nodes per plant, Fruit yield per hectare (q).Conversely, traits such as the number of branches per vine, node of first female flower emergence, days to first female flower appearance, number of female flowers per vine, number of fruits per vine, and fruit yield per vine, Fruit yield per plot (kg)demonstrated lower genetic advance. The observed variability across all traits underscores the potential for simple selection methods to enhance these characteristics in future breeding programs.
