‘Kadarka’ originating from the Balkan Peninsula used to be the most commonly grown cultivar in Hungry for centu-ries. It played a huge role in spreading red wine production in Hungary. As a result of different ecological and techno-logical conditions many ‘Kadarka’ clones and variants can be differentiated from each other in morphological and quality characteristics. We studied the variability of ‘Kadarka’ by examining the composition of an old plantation (established in 1898) and ‘Kadarka’ varieties from a gene bank and cultivars co-cultivated with ‘Kadarka’ (altogether 33 items). Our aim was to analyze the relationship between the numerous ‘Kadarka’ clones and variants based on their morphological and genetic traits and to clarify synonymy and homonymy not only among ‘Kadarka’ named, but also the ‘co-cultivated’ varieties. For ampelographic characterization we used OIV descriptors and Kruskal's Non-metric Multidimensional Scaling – NMDS and we applied SSR fingerprints for determining the genetic distances. Among the selected clones two main types, ‘Kadarka’ and ‘Olasz kadarka’ could be discriminated in the old plantation, which have different morphological traits and microsatellite profiles. Other varieties (‘Lúdtalpú kadarka’, ‘Ménesi kadarka’, ‘Virághegyi kadarka’) originating from gene banks could also partly be categorized into two main types. Morphological and genetic comparison support that ‘Csókaszőlő’ planted in the 19th century together with the ‘Kadarka’, shows close relationship with ‘Mészi kadarka’. We confirmed the hypothesis that ‘Fehér kadarka’ and ‘Öreg kadarka’ are not in close relationship with ‘Kadarka’. We demonstrated that ‘Szagos kadarka’ and ‘Halápi szagos’, as well as ‘Rácfekete’ and ‘Cigányszőlő’, considered to be distinct cultivars, are identical, that is they are synonyms and not ‘Kadarka’ vari-eties.
