Study of Combining Ability Analysis in Cherry Tomato (Solanum lycopersicum var. cerasiforme)

The study aimed to show the best effect of general combining ability (GCA) and specific (SCA) for parents their hybrids studied traits. included two main successive seasons. In first season, cherry tomato pure lines were selected that introduced from Tomato Genetics Resource Center (TGRC) at University California, Davis in USA, 5 which most genetically Distant are (LA4451, LA4753, LA3334, LA1221 LA4689) its code (1, 2, 3, 4 5) respectively entered into Full Diallel crossing program produce individual crosses. second season an experiment compare genotypes (5 + 20 cross-hybrids. reciprocal hybrids) according RCBD design with three replications. results as follows: 1 showed a significant combine desired direction terms fruit set percentage weight, while superiority parent plant yield total yield. was superior number flowers inflorescence, fruits, whereas hybrid (5×1) inflorescence 35.667, 259.66, 15.69 fruits 86.83. (1×4) appeared shown desirable traits average weight 1.47, 0.55 0.69.
