The objective of the project were grapevine viruses with special accent on Grapevine leafroll-associated virus 3 (GLRaV-3). Croatia is characterized by numerous autochthonous grapevine cultivars that represent national heritage. Unfortunately, beside good agronomic traits, autochthonous cultivars are characterized by high infection rate with different viruses that have negative impact on their production. The aim of the project was to test autochthonous grapevine cultivars on a scale of viruses with special accent on GLRaV-3 as prevalent and most important virus in Croatia and California. During the project typing of Croatian GLRaV-3 isolates were done together with transmission experiments using vine mealybug (Planococcus ficus). Also, sanitary status of some vines was ascertained using next generation sequencing. The results represent significant contribution to the existing knowledge of sanitary status of autochthonous Croatian grapevine cultivars. Beside that, project implementation created prerequisites for further investigation of grapevine viruses and their ecology in Croatia.
