An experiment was conducted during 2013-15 at Department of Vegetable Science, Kittur Rani Channamma College of Horticulture, Arabhavi, Belagavi (Karnataka), to study combining ability in eight different lines of ridge gourd. They were mated in half diallel fashion and their twenty eight crosses were evaluated along with parents in Randomized block design (RBD). Significant differences of analysis of variances due to SCA and GCA were observed for all the characters, it indicates predominance of non additive and additive gene action, that provides ample scope for heterosis breeding or direct selection. Out of eight parents DMRG-36 and DMRG-25 were found to be best general combiners as they have made significant contribution towards yield and yield contributing traits. The cross DMRG-36 x Arka Sumeet exhibited high SCA effect for number of fruit yield per vine, average fruit weight and sex ratio. The cross DMRG-25 × DMRG-1 for per cent fruit set and average fruit weight. The cross DMRG-25 × Arka Sumeet for average fruit weight, number of fruit per vine and fruit diameter. The knowledge of combining ability helps in identifying suitable parents or best combiners for hybridization.
