Clarification of homonymy (misnaming) for a grapevine cultivar in Georgia: the case of 'Moldova' alias 'Aladasturi'

Two different grape cultivars are grown in Georgia under the name 'Aladasturi', one in the West and one in the East part of the Country. Investigation of ampelographic and ampelometric parameters and nuclear microsatellite markers demonstrated, that the cultivar from West Georgia is the real Georgian autochthonous wine and table grape cultivar 'Aladasturi', while the cultivar from East Georgia is the table grape cultivar 'Moldova' with high resistance to downy mildew, obtained in the Republic of Moldova in the 1960s. This cultivar was probably introduced to Georgia in the period of 1970-1980s. Similarity of berry and bunch characteristics of 'Moldova' and 'Aladasturi' might be the reason for creation of homonymy, respectively misnaming. The homonymous 'Aladasturi' finally turned out to be a misnomer.
