Ecological Aspects and Conservation of Wild Grapevine Populations in the S.W. of the Iberian Peninsula

Populations of wild grapevine, Vitis vinifera L. subsp. sylvestris (Gmelin) Hegi, were discovered in S.W. of the Iberian Peninsula over the last years. Location, ecological aspects, sanitary characteristics, including the ELISA test to detect specific virus attack, are described. In vitro propagation and conservation are also considered. The paper also contains a global description of female and male individuals. This material could be used to start breeding programs of cultivated varieties and also to restore riverbank forests, which constitute one of the worst preserved ecosystems in the area

Identifying populations of wild vines and grapevines trained on the facades of old farmhouses.

El presente trabajo se ha centrado sobre la Cuadrilla de Ayala (Álava), donde se han localizado ocho poblaciones relictas de vid silvestre en diversos hábitats. Se ha comprobado su carácter dioico durante el periodo de floración. Se han identificado las principales especies parásitas existentes sobre estas parras y las principales componentes de su vegetación acompañante. Por otro lado, se han estudiado quince vides cultivadas, con una edad superior a cincuenta años, situadas en la fachada principal de los caseríos. El análisis del ADN de ambos tipos de parras se ha realizado con 48 marcadores SNPs. Los resultados obtenidos han sido comparados con la base de datos disponible en el Instituto de Ciencias de la Vid y del Vino (Logroño), a fin de proceder a la caracterización genética de las muestras.This paper focuses on the Cuadrilla de Ayala (Álava province, Spain), where eight relic wild grapevine populations were located in different habitats. The dioecious nature of these lianas was determined at flowering time. The main parasitic species on these vines and also the most frequent taxa of their accompanying vegetation were identified. On the other hand, fifteen vines, aged in excess of fifty, and located in the main entrances of traditional farmhouses (caseríos), were also studied. The analysis of the DNA from both kinds of sampled vines was based on 48 SNPs markers. Results were compared with the available data base at the Instituto de Ciencias de la Vid y del Vino (Logroño, Spain) for the sample genetic characterization
