Vitis vinifera cultivars are susceptible to powdery mildew (Erysiphe necator (Schw.) Burr.), but there are significant differences among them. Some of them originating from Middle-Asia, especially the cultivar 'Kishmish vatkana', do not show symptoms either after natural or artificial infection. Muscadinia rotundifolia has immunity to most pathogens infecting grapevine. French breeders determined that the extreme resistance to powdery mildew is dominantly inherited due to the RUN1 gene. Starting in 2000, our breeding project aimed to extend the cultivar assortment for wine and table grape varieties of high quality (like widespread European varieties) and at the same time immune to powdery mildew. We crossed the M. rotundifolia x V. vinifera BC3 and BC4 hybrids with V. amurensis x V. vinifera hybrids, V. vinifera cultivars, and other complex hybrids. The progeny were scored for resistance after artificial inoculation in the laboratory and natural infection in the field. The resistant: susceptible ratios were 1:1 proving the dominant inheritance of the RUN1 gene. The Vitis vinifera origin of powdery mildew resistance is a curiosity not only from thr breeding, but also from the evolutionary and pathological point of view, since it is not the result of host-pathogen coevolution but rather due to abiotic stress adaptation. In the progeny of a cross of the susceptible V. vinifera 'Nimrang' and the resistant V. vinifera 'Kishmish vatkana' a dominant form of inheritance was found. The resistance of 'Kishmish vatkana' (REN1 gene) is a further valuable source for breeding high quality resistant varieties. This kind of abiotic stress resistance that is effective against fungi has not yet been explored in-depth. We are taking the first steps in the analysis of the molecular genetic background of the resistance by proving the pure Vitis vinifera origin of 'Kishmish vatkana' with vinifera specific markers, and we are searching for SSR markers linked to resistance genes.
