Presumed Synonyms and Homonyms with Croatian Grapevine Cultivars

Due to great differences in climate and soil conditions, Croatia in spite of its small geographical size has many wine-growing regions where plenty of autochthonous wine grape cultivars arisen. In the past these cultivars were of important economic value, and some of them retained importance until now, especially in Dalmatia. During the history wine grape was propagated vegetatively by cuttings, which occasionally were taken from one region and introduced in another, disregarding the cultivar name. In new place the cultivar got the new name, or existing name was alternated in accordance with local dialect. This is especially true for Dalmatia where considerable dialectal differences might have been caused by many islands and coast indentedness. The result is the existence of great number of homonyms as well as synonyms in the names of cultivars. Due to the lack of ampelographic collection vineyards, it was not possible to reliably verify these homonyms and synonyms. Consequently, the real number of cultivars and their "true to type" has not been known. The goal of this research is the survey of several groups and pairs of potential homonyms and synonyms by means of RAPD markers. This should be a new contribution to more real estimation of the total number of autochthonous cultivars widespread over the territory of Croatia. Groups are established on the basis of lexical similarities in the names of cultivars, as well as on the basis of ampelographic similarities and differences among phenotype of particular cultivars. On the basis of RAPD analysis of previously presumed as identical, the difference between genetic profiles of cv. Glavanjuša and cv. Glavinuša is revealed. Two phenotypically different accessions bearing the same name, Gustopupica, are proved to have different genetic profile. However, out of four phenotypically different accessions with the name Dišeća ranina, three had the same genetic profile but the fourth one was different. Results for this and another several groups will be presented at the poster and could be of high importance in germplasm collecting and production of propagation material.
