Abstract:
In 2015, the cultivated area encompassing table grape varieties in Kosovo was 747 ha. Among these table grape variety types, the most cultivated variety is Muscat d’Hambourg comprising an area of 257 ha, followed by Italian muscat variety with 168 ha and Afuz Ali variety which covers 121 ha. As to the other varieties, they are cultivated in smaller areas and comprise 201 ha of total table grape cultivated area. This study was conducted in several farms in Rahovec municipality where viniculture is developed. During December 2017, 40 grapevine samples including Muscat d’Hambourg and Italian Riesling varieties were collected from five commercial vineyards. Each sample consisted of 3-4 cuttings which had a length of 30-40 cm. Until they were tested, the samples remained stored at a temperature of 4°C. The sanitary assessment of the collected samples was carried out by applying the Serological assays – ELISA diagnostic method. All samples (40) were tested for six viruses, including Nepovirus (GFLV), Closterovirus (GLRaV-2), Ampeloviruses (GLRaV-1, GLRaV-3), Vitivirus (GVB) and Vitivirus (GVA). According to ELISA virus detection test results, 95% of Italian Riesling variety samples were infected by GLRaV-1, GLRaV-3 and GVA viruses, whereas 65% of Muscat d’Hambourg variety samples were infected by GLRaV-1, GLRaV-3 and GVA viruses. There was not any indication signifying that the samples were infected by Nepovirus (GFLV), Closterovirus (GLRaV-2) or Vitivirus (GVB).
