Line × Tester Analysis and Estimating Combining Abilities for Yield and Some Quality Attributes in Tomato (Solanum lycopersicum L.)

General and specific combining ability (GCA & SCA) for yield and quality traits in tomato were studied by involving fourteen parental line were crossed in line x tester mating design comprising eleven line and three tester at M.E.S department of vegetable science ANDUAT, Ayodhya to estimate combining ability in tomato for fruit yield and quality traits. Combining ability analysis revealed that both additive and non-additive gene action for most of the characteristics and heterosis breeding for the improvement of these traits have been enhanced. Based on GCA effects of parents, the line NDT-4 and the testers Kashi chayan were identified as the best general combiner for yield and its important component. The crosses NDT-2×Arka vikash superior specific combiners for fruit yield per plant.
