The variety was obtained within a breeding program to create grapes adapted to the arid conditions of the Murcia region. The genotype demonstrates the ability to maintain yield levels without irrigation and is being studied for resistance to powdery mildew.
A key feature is the production of berries with a low Baumé scale value, which allows for the production of wines with a moderate alcohol content. Analysis of the must composition revealed a specific amino acid profile with low proline accumulation, and the content of anthocyanins and flavonols was also analyzed.
During field trials in 2017–2019, the hybrid showed high yield, reaching 5.4 kg per vine in 2019. MS104 is a working breeding number and is used exclusively for scientific purposes.
