Reconstruction of a grapevine pedigree by microsatellite analysis

Microsatellites are ideal markers for revealing genetic relationships between individuals because of their co-dominant inheritance. In this study we determined the genetic profiles of 52 grapevine cultivars using 32 microsatellite markers. We were able to define the complex genetic relationship among nine European grapevine cultivars. None of these parent-offspring combinations were anticipated beforehand. The ancient cultivar Silvaner is shown to be an offspring from Traminer and Osterreichisch Weiss. Rotgipfler originates from a cross between Traminer and Roter Veltliner, while Fruhroter Veltliner originates from Roter Veltliner x Silvaner and Fruhroter Veltliner x Portugieser gave rise to Jubilaumsrebe. A pedigree illustrating the putative crosses was reconstructed.
