Abstract

Viticulture is worldwide endangered by powdery (Erysiphe necator) and downy mildew (Plasmopara viticola) fungal diseases. These pathogens derive from North America and got into Europe with infected grape cuttings in the 19th century. Because of the vulnerability of the traditional European grapevine cultivars an interspecific hybrid breeding program was started in France with crossing Vitis species originating from North America and V. vinifera L. varieties. The results of this activity pioneered by Albert Seibel, Bertille Seyve and Victor Villard were hybrids having good quality and carrying partial resistance against fungal pathogens. 'Seibel' and 'Seyve-Villard' grapes were applied in the resistance breeding programs in Hungary, too. We analyzed 22 out of these hybrids, their putative parents and international reference varieties (altogether  40 genotypes) with microsatellite  and ScORA7-760 resistance QTL-linked marker.
