| Abstract: | The arrival of powdery mildew, phylloxera, and then downy mildew from America in the late 19th/early 20th century, was one of the most important causes of the loss of grapevine diversity in Europe. Many varieties traditionally grown in small winemaking areas of Europe were substituted by direct producing hybrids or by a small number of varieties from other vine-growing areas. For geographic, economic, sociological, and cultural reasons, the north and northwest of Spain acts as a kind of refuge area where grapevine diversity is still high. At the Misión Biológica de Galicia (CSIC) research station a collection of living vines with a number of dispersed individuals belonging to old varieties was established in 1992. Many of these varieties had practically disappeared from vineyards and the majority existed only as centuries-old individuals. |
