Abstract
Twelve genotype of spine gourd were evaluated to estimate the variability, heritability and genetic advance in Randomized Block Design with three replications at Horticulture Instructional farm, COA, IGKV, Raipur (C.G) during Kharif 2018. Results of genetic variability indicated that mean sum of squares due to genotypes were highly significant for all the characters. On the basis of mean performance, genotypes like C.G Kankoda-2, RMD 15-2, NDMD 16-1, ASG 16-1 and ASG 18-1 were found higher yielder, early flowering and better growth along with other desirable characters. Higher GCV and PCV was observed for fruit yield per plant, number of branches per plant, number of fruits per plant, 100 seed weight and average fruit weight. High heritability accompanied with high genetic advance as percentage of mean was found for traits viz., fruit yield per plant, number of fruits per plant, average fruit weight, 100 seed weight and days to first female flowering node which indicated predominance of additive gene action.
