Abstract
The present investigation was conducted to understand these parameters, which form an integral part of a programme for making improvements in snake gourd yield and its contributing characters. The present investigation was carried out with 32 snake gourd genotypes during late kharif 2021-22. There was need for more genetic research because the genotypes for every character under study differed significantly. Average fruit weight, fruit yield per vine, number of seeds per fruit, node to first female flower, fruit length, fiber content, acidity content, and potassium content all showed high values of PCV with correspondingly high values of GCV, indicating a greater degree of variability that could be attributed to genotype. Selection was very successful for these characters because of their high heritability and high genetic advance as measured by the percentage of mean for the following traits: fruit set percentage, fruit length, average fruit weight, flesh thickness, number of seeds per fruit, number of fruits per vine, fruit yield per vine, acidity content, and potassium content. Heritability was primarily caused by additive gene effect.
