The red variety comes from Croatia. Synonyms are Corbina, Karbonera, Markolina, Negrara, Negrona ( Italy ); Hrvatica Crna, Jarbola ( Croatia ). The assumption that they are with the Italian Croatina (with the same name meaning) was identical, was made by 1999 DNA analysis disproved. It has also been found that the blackberry Jarbola is identical. On the other hand, a white-berry variety called Jarbola bijela is not related. The early to medium-maturing, high-yielding vine is particularly susceptible to wrong mildew, The not very dark colored berries are well suited for rosé wines. The variety is cultivated in the northwest of the Croatian peninsula of Istria, but no stock was reported in 2010. In Italy, it is under Negrara especially in Veneto and Apulia cultivated; In 2010, 116 hectares were recorded here (Kym Anderson ).
