Zdravstveno stanje autohtonih kultivara vinove loze u Istri

Croatia is at present faced with rapid erosion of the autochthonous grapevine germplasm due to introduction of the famous European cultivars. A program for conserving grapevine genetic resources as well as clonal selection of the most commercially important Istrian autochthonous varieties is ongoing. In order to detect the vines affected by severe virus diseases we have provided the three years ELISA screening. Viruses tested by ELISA were: grapevine fanleaf virus (GFLV), grapevine fleck virus (GFkV), Arabis mosaic virus (ArMV), grapevine virus A (GVA) and grapevine leafroll associated viruses 1 and 3 (GLRaV 1 and GLRaV 3). All these viruses except ArMV were detected and mixed infections were also identified. Results revealed the worrying health condition of autochthonous Istrian cultivars, and a better sanitary state of older and geographically isolated vines have emerged. This underlines the necessity of efficient selection programs and producing of virus-free grapevine propagation material.
