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