In the CIAGRO-UMH´s Traditional Tomato Varieties Improvement Program, the genes Tm-2a (which provides resistance to ToMV), Sw-5 (which provides resistance to TSWV) and Ty-1 (which provides tolerance to TYLCV) were successfully incorporated into the Muchamiel lines. However, it has been detected that the inclusion of the Ty-1 gene has negative effects, since the lines improved with this gene show inferior agronomic and organoleptic characteristics compared to their parents. Therefore, the possibility of exploring alternatives is being considered, including the incorporation of the ty-5 gene, which also offers tolerance to TYLCV. This study analyzes the impact of the introduction of the Ty-1 and ty-5 genes in two Muchamiel tomato lines from the breeding program. To this end, agronomic characteristics (such as the number of fruits per plant, average fruit weight and total production) and quality characteristics (including soluble solids content and titratable acidity) were evaluated. Once the results obtained in this trial have been analyzed, we can see that the Ty-1 gene has no negative effect on production, average weight and total acidity, while it does not have any negative effect on the number of fruits and soluble solids. In the case of the ty-5 gene, the results show that it does have a negative effect on production, number of fruits, average weight and total acidity, being little noticeable in terms of the number of fruits and total acidity and having no negative effect on the parameter of total soluble solids.
