The red grape variety comes from Croatia. Synonyms are Corbina, Crevatizza, Karbonera, Markolina, Negrara, Negrona (Italy); Hrvatica Crna, Jarbola (Croatia). The parentage (parenthood) is unknown. The assumption that she is identical with the Italian Croatina (with the same name meaning) was disproved by DNA analyses carried out in 1999. It also turned out that the black berry variety Jarbola is identical. In contrast, a white-berry variety called Jarbola Bijela is not related. The early to medium-ripening, high-yielding vine is particularly susceptible to downy mildew. It produces rather poorly coloured red wines, which makes it more suitable for rosé wines. The variety is cultivated in the northwest of the Croatian peninsula of Istria. In Italy, it is mainly cultivated in Veneto and Apulia on 53 hectares of vineyards, with a sharply declining tendency. In 2016, however, only one Italian stock was identified (statistics Kym Anderson).
