First report of Grapevine Pinot gris virus in Georgia
Grapevine Pinot gris virus (Trichovirus, GPGV) was detected for the first time in Georgia during a survey carried out in autumn 2013 to assess the sanitary status of local grapevine cultivars (Vitis vinifera). Leaf samples were collected from 37 grapevine plants belonging to 25 different cultivars (white and red) and tested (RT-PCR, sequencing). GPGV was detected in 8 plants (white cvs. ‘Goruli mtsvane’, ‘Khikvi’, ‘Mtsvane kviteli’ and red cvs ‘Saperavi pachkha’, ‘Tavkveri’, ‘Korkaula’). It is noted that further investigations are needed to determine which symptoms are associated with GPGV and to evaluate the potential impacts of GPGV on yield and wine quality.
