Abstract:
Ten diverse lines of cherry tomato were crossed in half diallel fashion to study the combining ability effects for various quantitative traits. Analysis of variance revealed significant differences for all the traits under both environments. The magnitude of sca variance was higher than the corresponding gca variance for all the traits under study, indicating the prevalence of non-additive gene action for all the traits except for days to first flowering, days to first fruit set and days to first fruit maturity in E₁ and data pooled over environments. Based on GCA effects of parents, lines WIR-5032, EC-520074 and EC-914092 in E₁ and lines WIR-3957, WIR-5032 and Sun Cherry in E₂ were found to be good general combiners for most of the traits. The crosses WIR-5032 x WIR-3957, EC-914115 x VRT-02 and EC-520074 x EC-520078 in E₁ and EC-520078 x VRT-02, EC-914092 x VRT-02 and EC-165690 x WIR-3957 in E₂ were found to be the superior cross combinations on the basis of fruit yield plant^-1.
