Study on Genetic Parameters and Character Association in Ridge Gourd (Luffa acutangula Roxb.)

Abstract

The experiment was carried out on Genetic variability and character association in eight genotypes of Ridge Gourd with three replications during summer season 2021-22 at the Research Field of Department of Horticulture, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj, India. The observations were recorded on various yield and yield contributing characters of ridge gourd. The results from the present investigation revealed that on the basis of Based on mean performance for fruit yield per plant (2.17 kg) and fruit yield (88.35 q/ha), genotypes IET 2021/RIGVAR-6 were considered suitable genotypes in Prayagraj climatic condition. Coefficient of variation revealed that high magnitude of GCV and PCV were recorded for Fruit yield/ ha (q) and Average fruit weight (g). The heritability estimates were found to be high (greater than 60%). The genetic advance and genetic advance as a percentage of mean estimates were found to be significant (more than 20%). Genotypic correlation coefficient analysis revealed that fruit yield /ha (kg) showed positive significant association with Fruit length (cm) (0.024**), Fruit diameter (cm) (0.971**), Number of fruit per plant (0.331**), Average fruit weight (g) (0.940**) at genotypic level. Whereas Phenotypic correlation coefficient analysis revealed that fruit yield /ha (kg) showed positive significant association with Fruit length (cm) (0.347**), Fruit diameter (cm) (0.999**), Number of fruit per plant (0.653**), Average fruit weight (g) (0.999**) at phenotypic level.
