Although the population shows a marked sylvestris character, it cannot be concluded that it is purely autochthonous, and should be considered as spontaneous and of hybrid type {\textemdash} that is, the result of the hybridization of autochthonous wild vines with other post-cultivated or subspontaneous forms.}, issn = {0002-9254}, URL = {https://www.ajevonline.org/content/50/4/443}, eprint = {https://www.ajevonline.org/content/50/4/443.full.pdf}, journal = {American Journal of Enology and Viticulture} }
