The authors identified yeast strains from the following grape cultivars: Rhein Riesling -DEN1- (7-2018); Cabernet -ZH-3 (9-2018) and L-3 (6-2018); Flora -DEN-5 (10-2018). According to the analysis results of nucleotide sequence that codes part of rRNA genes, performed in BRC VKPM NRC “Kurchatov Institute” – State Research Institute of Genetics, it was found that DEN-1 (7-2018) strain belongs to the species Metschnikowia pulcherrima; ZH-1 (9-2018) strain is closest to the species Pichia kluyveri; L-3 (6-2018) strain is the representative of the species Metschnikowia pulcherrima and DEN-5 (10-2018) belongs to thespecies Pichia kudriavzevii. The studies confirm that the grape cultivars – Rhein Riesling, Cabernet, Flora, introduced in the Republic of North Ossetia-Alania, are promising natural resource of systematic yeast diversity.
