Characterization of Grapevine Rootstocks using Microsatelite Markers

ABSTRACT Twenty rootstock accessions from Bulgaria and Cyprus grapevine (Vitis spp.) collection were characterized through microsatellite analysis. The application of 14 highly polymorphic microsatellite markers revealed high genetic diversity (83%) and allowed accurate identification and discrimination of tested cultivars. The dendrogram constructed on the base of microsatellite allele data demonstrated the genetic kinship between investigated rootstocks. The parentage of Bulgarian rootstock MK4, derived by cross between Bulgarian ancient cultivar Mavrud and Rupestris du Lot was proved.
