Phytosanitary status of grapevine in Montenegro.

During 2006 and 2007, a survey on the incidence and distribution of fourteen grapevine viruses was carried out in the Skadar Lake basin, one of the two main grapevine-growing areas of Montenegro. In total 165 samples were collected from four red ('Vranac', 'Kratošija', 'Merlot' and 'Cardinal'), two white ('Chardonnay' and 'Rkaciteli') and a few unknown grapevine varieties in the vicinity of Podgorica and Bar. The phytosanitary status of the collected samples was analysed by DAS- ELISA and the presence of Grapevine fanleaf virus ( GFLV), Grapevine leafroll-associated virus 1 ( GLRaV-1), Grapevine leafroll-associated virus 2 ( GLRaV-2) and Grapevine leafroll-associated virus 3 ( GLRaV-3) was confirmed in some of them. The most frequently found virus in assayed samples was GLRaV-3 (54.5%), followed by GFLV (23%), GLRaV-1 (20%) and GLRaV-2 (0.6%). These serological analyses showed the absence of Grapevine leafroll-associated virus 6 ( GLRaV-6), Grapevine leafroll-associated virus 7 ( GLRaV-7), Raspberry bushy dwarf virus ( RBDV), Strawberry latent ringspot virus ( SLRSV), Tomato ringspot virus (To RSV), Raspberry ringspot virus (Rp RSV), Arabis mosaic virus (Ar MV), Tobacco ringspot virus ( TRSV), Tomato black ring virus ( TBRV) and Cherry leaf roll virus ( CLRV) from all tested samples.
