A survey on viruses was carried out in 2008 in the main olive-growing areas of Albania (Kruja, Sauk and Vlora). A total of 50 samples, belonging to 14 local and 2 international cultivars, were collected in 10 different commercial orchards and one experimental field and checked using a one-step RT-PCR for the presence of Arabis mosaic virus (ArMV), Cherry leaf roll virus (CLRV), Strawberry latent ringspot virus (SLRV), Olive latent virus 1 (OLV-1), Olive leaf yellowing-associated virus (OLYaV), Cucumber mosaic virus (CMV), Olive latent virus-2 (OLV-2) and Tobacco necrosis virus strain D (TNV-D), using virus-specific primers. All samples were found healthy with the exception of a ‘K. M. Berat’ olive tree, infected with both SLRSV and OLYaV and belonging to the experimental field. These results become particularly important when related to the phytosanitary state of other Mediterranean countries, where the incidence of viruses in a considerable percentage has been ascertained. Keeping this in the mind, it is absolutely necessary to keep the Albanian olive germplasm into consideration for its quality both from an agronomical and a phytosanitary point of view.
