Description of ampelografic characteristics and isoenzymatic and genetic characterization of variety Hrvatica

There are many old varieties present in Istria (Croatia) that haven't been ampelographically characterized yet and which are know under the different synonymous. One of them is Hrvatica, the old variety also known as Croatina, Crovattina, Crevatizza, Carbonera and etc. We have collected the ampelographic characteristics of Hrvatica and upon them, we tried to determinate the similarity with other varieties, using the isoenzymatic and DNA analysis, too. Ampelography has been done including 43 characteristics from OIV descriptor list. Main phenological stages werw also recorded. Ten mature leaves were used for pjilometry, ten aerage grapes were measured uvometrical and the chemical analysis of the must was done. Isoenzymatic analysis was carried out for two isoenzymativ codes (GPI and PGM) and DNA analysis was also done on the nine SSR loci. As to the ampelographic data we concluded that Hrvatica could be, in terms of economy, an important variety. Based on the ampelographic, isoenzymatic and DNA analysis it was confirmed that it differs from the variety Croatina.
