This study assessed the genetic variability, heritability, and genetic progress of 25 genotypes of sponge gourd [Luffa cylindrica L. (Roem.)]. In this randomized block design experiment with three replications, twenty yield and quality characteristics were evaluated. The significant differences between genotypes discovered by the analysis of variance demonstrate the high level of genetic diversity. Traits like dry matter content, chlorophyll content, vine length, and number of primary branches showed high genotypic and phenotypic coefficients of variation, heritability, and genetic advancement, suggesting their potential for effective selection and genetic advancement. Certain genotypes, such as VRSG-517 and NDSG-23-1, showed superior performance in yield from that of the check variety (Pusa Chikni). The findings indicate that traditional breeding operations can consistently address these traits to produce improved cultivars of sponge gourd.
