Abstract:
In order to determine the magnitude of variability, 18 genotypes of ivy gourd were evaluated at CHES, Bhubaneswar. Through analysis of variance, a high significant difference was found for almost all thirteen characters indicating a greater opportunity of exploit variability. Genotypic and phenotypic variances were highest for no. of fruit yield /plant and stem girth followed by leaf area and days of flowering. Phenotypic co- efficient of variation (PCV) and Genotypic co-efficient of variation (GCV) were maximum in case of no. of primary branches/plant and minimum for length of internode, respectively. Heritability was found very high for all characters except length of internode and fruit girth. The maximum genetic advance (% of mean) was observed in case of no. of fruit/ plants followed by leaf area and days of flowering. Genotypic coefficient of variation, heritability and predicted genetic gain were high for the characters no. of primary branches/plant, vine length and no. of fruit/ plants suggesting that additive gene action is responsible for expression of these characters.
