Abstract:
Using genetic hybridisation analysis and molecular karyotyping we revealed an association of Saccharomyces bayanus var. uvarum species with Tokaj wine-making. Along with identification of Saccharomyces strains isolated by E. Minárik in Slovakia, the composition of Tokaj populations in Hungary was studied. Twenty-eight Hungarian Saccharomyces strains were analysed in terms of karyotype. The majority of strains belong to S. bayanus var. uvarum. Two non-identified Saccharomyces strains were found to be polyploid according to their complex karyotype patterns.
