%26apos;Kadarka%26apos; originating from the Balkan Peninsula used to be the most commonly grown cultivar in Hungry for centuries. It played a huge role in spreading red wine production in Hungary. As a result of different ecological and technological conditions many %26apos;Kadarka%26apos; clones and variants can be differentiated from each other in morphological and quality characteristics. We studied the variability of %26apos;Kadarka%26apos; by examining the composition of an old plantation (established in 1898) and %26apos;Kadarka%26apos; varieties from a gene bank and cultivars co-cultivated with %26apos;Kadarka%26apos; (altogether 33 items). Our aim was to analyze the relationship between the numerous %26apos;Kadarka%26apos; clones and variants based on their morphological and genetic traits and to clarify synonymy and homonymy not only among Kadarka%26apos; named, but also the %26apos;co-cultivated%26apos; varieties. For ampelographic characterization we used OIV descriptors and KRUSKAL%26apos;s Non-metric Multidimensional Scaling - NMDS and we applied SSR fingerprints for determining the genetic distances. Among the selected clones two main types, %26apos;Kadarka%26apos; and Olasz kadarka%26apos; could be discriminated in the old plantation, which have different morphological traits and microsatellite profiles. Other varieties (%26apos;Ludtalpu kadarka; Menesi kadarka; %26apos;Viraghegyi kadarka) originating from gene banks could also partly be categorized into two main types. Morphological and genetic comparison support that Csokaszolo%26apos; planted in the 19th century together with the Kadarka; shows close relationship with Meszi kadarka%26apos;. We confirmed the hypothesis that %26apos;Feher kadarka%26apos; and Dreg kadarka%26apos; are not in close relationship with Kadarka%26apos;. We demonstrated that Szagos kadarka%26apos; and %26apos;Halapi szagos, as well as Racfekete%26apos; and Ciganyszolo; considered to be distinct cultivars, are identical, that is they are synonyms and not %26apos;Kadarka%26apos; varieties.
