Description
Summary:Sanitary status of visually selected and nonselected indigenous grapevine cultivar 'Refosk' (Vitis vinifera L. cv. 'Refosk') was evaluated. Nine viruses were tested by ELISA: Nepoviruses Grapevine fanleaf virus (GFLV) and Arabis mosaic virus (ArMV), Closteroviruses Grapevine leafroll associated viruses 1 (GLRaV-1), 2 (GLRaV-2), 3 (GLRaV-3), and 6 (GLRaV-6), Grapevine fleck virus (GFkV) and Vitiviruses Grapevine virus A (GVA) and Grapevine virus B (GVB). All viruses except ArMV and GVB were detected. The vines of cv. ‘Refosk’ passing the visual selection were 50 % free of tested viruses in comparison to only 24 % virus-free vines of non-visually selected material. Visually selected plants revealed the highest incidence of virus GLRaV- 1 (37 %) and in addition to that a 15 % incidence of rugose wood (RW) disease symptoms.
