First report of Grapevine Pinot gris virus in Turkey
Since 2014, symptoms of leaf deformation and mottling with reduced fruit yield and quality have been observed on grapevine (Vitis vinifera cvs. ‘Chardonnay’, ‘Emir’, ‘Kadın parmağı’, ‘Muscat of Hamburg’, ‘Pinot noir’) in the Tekirdağ province of Turkey (Marmara region). Laboratory analysis confirmed the presence of Grapevine Pinot gris virus (Trichovirus, GPGV) and several other viruses (i.e. Grapevine leaf roll associated virus 1 and 3, Grapevine fanleaf and Grapevine fleck virus) in all tested samples except those collected from cv. ‘Muscat of Hamburg’. This is the first time that GPGV is reported from Turkey.
