Since 1998, inventarization of grapevine varieties is carried out throughout Croatia. During inventarization primary ampelographic evaluation and marking of vines is carried out. Tissue samples for DNA analyses are taken from interesting vines. Database with ampelographic description and genetic profiles is being created and it will be part of most important European Vitis databases.

Ongoing scientific research activities include the analyses of intravarietal variability of most important autochtonus grapevine varieties using ampelographic description and amphelometric measurements and molecular markers.
