Abstract

The wild grapevine, Vitis vinifera ssp. silvestris (also called autochthonous “lambrusque” in French), is an endangered and rare plant in France and Europe. Until now, no accurate inventory was available in France and the characterisation of this wild grapevine compartment was quite lacunary. Prospectings realised in 2000 and 2001 have permited to inventory 135 french sites with wild grapevines. A total of 517 individuals have been found of wich about 330 would be Vitis vinifera ssp. silvestris based on morphology. An analysis more precise of a sub-sample of 154 individuals selected randomly was done. Those 154 individuals come from 4 regions: Aquitaine, Corse, Languedoc-Roussillon and Midi-Pyrénées. All individuals have been observed on trees or shrub foliation, in forest, hedge (closed to roads and fields) and in Mediterranean garrigue or bush. Based on their morphology, 132 of those individuals were considered as “lambrusques”. A statistical analysis (CFA) done on morphological data doesn't reveal any geographical structuration. The silvestris and the “other wild grapevines” are not very differentiated. The molecular analysis of the 154 prospected individuals with 13 microsatellite loci reveals meanwhile a clear structuration according to the geographical origin: thus the wild grapevines from Corse are clearly differentiated with “continental” ones by Principal Component Analysis. In order to understand the relation between wild and cultivated compartments, we compared those data with others obtained on a 110 cultivars sample originated from different locations. A clear differentiation is observed between the two compartments and the French cultivars seem to be more related to French wild grapevines than the cultivars originated from distant countries. A reflection is also presented on applying this knowledge on management of wild grapevine resources.
