| Abstract | ||
| The inheritance studies of some quantitative and qualitative characteristics of tomato were carried out using a half diallel crosses mating design to obtain 15 crosses among 6 genotypes. General (GCA) and Specific (SCA) combining abilities were significant or highly significant for all studied traits. The large magnitude of (GCA) for the vegetative, and total soluble solids (TSS %) traits suggested the importance of additive genetic effects, while the large magnitude of (GCA) and (SCA) for fruit set percentage (FS %), earliness, total yield, average fruit weight (AFW), fruit firmness (FF), number of locules per-fruit (NL/F) and fruit thickness (FT) suggested the importance of additive and non-additive genetic effects. B5357 cultivar (P5) was a good combiner for plant height (PH), fruit set percentage (FS %), early fruit number (EFN), total fruit number (TFN), total fruit weight (TWF) and total soluble solids (TSS %). Edkawy cultivar (P2) also, was a good combiner for number of branches per plant (NB/P) and number of locules per-fruit (NLF) while Fline cultivar (P6) was a good combiner for average fruit weight (AFW), fruit firmness (FF), and fruit thickness (FT). | ||
