Environmental, sanitary and ampelographic characterization of wild grapevine in Western Pyrenées (Spain, France)

Abstract

Aims: The aim of this paper was to locate and describe the wild grapevine as a phytogenetic resource in Western Pyrenees, including Navarre, Aragon (Spain) and the department of Pyrénées atlantiques (France).

Methods and results: An ampelographic description of wild grapevine populations was made as well as a study of their oenological potential and an evaluation of their sanitary condition. The ampelographic results confirmed the dioecious nature of all the specimens. The microvinification results of two wine samples showed low alcohol content, high acidity (low pH) and high intensity of colour. The sanitary study revealed that the main parasites of the vines were eriophyids (mites), powdery and downy mildews (fungus), with aerial organs being most susceptible (leaves, bunches). No symptoms of phylloxera, nematodes or root destroying fungi were detected. The paper is complemented by a list of the main accompanying botanical species.

Conclusion: This phytogenetic resource is well represented in the area of study, exhibiting a good sanitary status.

Significance and impact of the study: This paper could provide the basis for future genetic studies addressing the possible links between the wild grapevines and the cultivated varieties of the region. Wild grapevines could also be used in future breeding programs.
