Relic wild grapevine populations (Vitis vinifera L. subsp. sylvestris (C.C.Gmel.) Hegi), were surveyed in Extremadura region (Spain). Twenty-two populations were found along river bank forests in Badajoz and Cáceres provinces. The main ampelographical characteristics and phenology of vines and the incidence of parasites were evaluated. Supporting flora has been botanically characterized. Results confirmed the dioecious characteristic of this grapevine subspecies and showed that Colomerus vitis (Pagenstecher) (Acari, Eriophyiidae) mite and powdery and downy mildews are the main parasites affecting their populations.Downloads
