Abstract:
A field experiment was conducted using 24 genotypes of bitter gourd including varieties, local collections from different regions of Karnataka during summer 2017-18. The experiment was carried out at experimental block, department of Crop improvement and Biotechnology, College of Horticulture, Mudigere, University of Agricultural and Horticultural Sciences, Shivmogga for yield and its attributing traits and analyzed for Genotypic Coefficient of Variation, Phenotypic Coefficient of Variation, heritability and genetic advance as per cent mean. High estimates of PCV (%), GCV (%), heritability coupled with high genetic advance as per cent mean were observed for node at which first male flower appears, node at which first female flower appears, sex ratio, number of fruits per vine, fruit weight (g), fruit length (cm), fruit width (mm), rind thickness (mm), flesh thickness (mm), fruit yield per vine (kg), fruit yield per plot (kg) and vitamin C (mg/100g). Hence, these characters were highly influenced by the additive gene action and could be used in genetic improvement through direct selection.
