Line x Tester analysis was carried out for ten diversified parents at the Department of Vegetable Science Kittur Rani Channamma College of Horticulture, Arabhavi, to study the combining ability for various characters in ridge gourd. Lines DWD local, ERG-2, ERG-1 and DMRG-1 were identified as good general combiners for yield appear to be worthy of exploitation in future hybrid development. It is suggested that population involving these lines may be developed through multiple crossing isolating high yielding varieties. The variance due to general combining ability (GCA), specific combining ability (SCA) and GCA to SCA ratio for various characters indicate that the presence of both additive and non-additive gene actions. The cross DWD local x CO-1, ERG-1 x Deepthi, IC-92637 x Deepthi, HSN local x CO-1 and DMRG-25 x Deepthi were identified as good specific combiners for total fruit yield per hectare in order of merit. These cross combinations can be utilized for further breeding programme for crop improvement in ridge gourd.
