| Abstract:
Due to their codominant inheritance microsatellites are ideal markers to reveal genetic relationships between individuals. We determined the genetic profiles of 52 grapevine cultivars using 32 microsatellite markers. Many of the cultivars which are of great economic importance, like Cabernet Sauvignon, have been selected and propagated centuries ago and often lack reliable documentation about their origins. Our data confirm the origin of Cabernet Sauvignon from a cross between Cabernet Franc and Sauvignon blanc. Furthermore we proved the parentage of the cultivars Neuburger (Silvaner x Veltliner rot), Blauburger (Portugieser blau x Blaufränkisch), Zweigelt (Blaufränkisch x St. Laurent) and Müller-Thurgau (Rheinriesling x Chasselas de Courtillier). We were able to define the complex genetic relationship among nine European grapevine cultivars. The ancient cultivar Silvaner is shown to be an offspring from Traminer and Österreichisch Wei  . Rotgipfler descends from a cross between Traminer and Roter Veltliner.
Frühroter Veltliner originates from Roter Veltliner x Silvaner and Frühroter Veltliner x Portugieser gave rise to Jubiläumsrebe.
A pedigree illustrating the putative crosses was reconstructed.
