Abstract:

An experiment was conducted on Genetic variability in the eighteen genotypes of Ridge Gourd during 2019-20 at the Research Field of Department of Horticulture, Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj. The observations were recorded on various yield and yield contributing characters. The results from the present investigation revealed that On the basis of Based on mean performance for fruit yield per plant (2.720 kg) and fruit yield ((24.480t/ha-1), genotypes 2017/RIGHYB-5 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 (ton) and Average fruit weight (g). The heritability estimates were found to be high (more than 60%). The genetic advance and genetic advance as percent of mean estimates were found to be high (more than 20%). Genotypic correlation coefficient analysis revealed that fruit yield plant-1 (kg) showed positive significant association with Fruit length (cm) (0.598**), Fruit diameter (cm) (0.741**), Rind thickness (mm) (0.514**), Flash thickness (mm) (0.523**), Number of fruit per plant (0.666**), Vine length (cm) at 90 DAS (0.275*) and Average fruit weight (g) (0.944**) at genotypic level. Whereas Phenotypic correlation coefficient analysis revealed that fruit yield plant-1 (kg) showed positive significant association with Fruit length (cm) (0.573**), Fruit diameter (cm) (0.709**), Rind thickness (mm) (0.509**), Flash thickness (mm) (0.504**), Number of fruit per plant (0.607**), Average fruit weight (g) (0.924**) and Vine length (cm) at 90 DAS (0.270*) at phenotypic level.
