First record of Grapevine Pinot gris virus infecting Vitis vinifera in the United Kingdom

Abstract

Grapevine Pinot gris virus (GPGV) is a member of the genus Trichovirus, and was first identified in grapevine (Vitis vinifera) cv. Pinot Gris in Italy in 2012 (Giampetruzzi et al., 2012). Since then GPGV has been reported in several European countries as well as Australia, Canada, China, Korea and the USA (Bertazzon et al., 2016). In April 2017, a survey of four geographically separated vineyards in the UK was done to investigate the presence of GPGV. A dormant cane was sampled at random from each of the four locations (Pinot Noir clones 119, 336, 792 and 924, reciprocally grafted upon Gravesac, SO4 or 3309 Couderc rootstocks)
