Abstract

During 2016, surveys were conducted in the Northern Guinea Savannah agroecological zone of Nigeria to document the occurrence of grapevine viruses and viroids. A total of 318 leaf tissue samples belonging to 5 cultivars were collected during the survey across 28 vineyards and analysed in the laboratory. The presence of Grapevine yellow speckle viroid 1, Grapevine yellow speckle viroid 2 and Hop stunt viroid were detected based on various molecular analyses. This is thought to be the first report of these viroids infecting grapevine in Nigeria.
