title: Differentiation of grapevine (Vitis viniferaL.)concultamembers based on molecular tools.
abstract: Twenty-seven grapevine (Vitis vinifera L.) varieties within 12 putative berry colour variation groups (conculta) were genotyped with 14 highly polymorphic microsatellite (simple sequence repeats (SSR)) markers. Three additional oligonucleotide primers were applied for the detection of the Gret1 retroelement insertion in the promoter region ofVvMybA1transcription factor gene regulating the UFGT (UDP-glucose: flavonoid 3-O-glucosyltransferase) activity. UFGT is the key enzyme of the anthocyanin biosynthetic pathway. SSR results proved that the analysed cultivars can be grouped only into nineconcultas, the other three putative berry colour variant groups consist of homonyms as a consequence of misnaming. In the case of Sárfehér-Sárpiros, Delaware red-Delaware white and Járdovány fekete-Járdovány fehér, it was attested that they are not bud sports, but homonyms. Someconcultamembers could be differentiated according to the presence or the absence of theGret1retroelement (Chasselas, Furmint and Lisztes), while others, Bajor, Bakator, Gohér and Traminerconcultamembers, remained indistinguishable either by the microsatellites or theGret1-based method.
