Combining ability analysis for processing characters and its related traits in tomato (Solanum lycopersicum L.)

Abstract

A set of 40 genotypes including seven females, four males, their 28 single F1 combinations and one definitive check (Abhinav) existed planted at Vegetable Research Scheme, R.H.R.S., NAU, Navsari. During research the combining ability in tomato (Solanum lycopersicum L.) for 8 characters following Line x Tester mating method, Elevated public incorporating capacity experimental in parents of viz., JTL-12-04, JTL-12-10, JTL-12-12, JT-3 and AT-3 for one or more yield contributing traits. In hybrids, JTL-12-12 × JT-3, NTL-1 × AT-3, JTL-12-12 × GT-2, NTL-1 × JT-3, JTL-12-11 × GT-2, JTL-12-10 × GT-2, JTL-12-04 × AT-3 and JTL-12-04 × GT-1 exemplified increased heterosis bonded with huge SCA consequences for fruit result. Mixing skill analysis indicated that importance of SCA disagreements occurred elevated than GCA frictions for all the identities under research, which implied that prevalence of non-additive gene effort for heritage of all the characteristics. Therefore, distant breeding programme exploitation of heterosis is reasonable.
