First report of Grapevine leafroll-associated virus 1 infecting grapevines (Vitis spp.) in Nigeria.
Surveys were conducted during 2016 across 28 grape vineyards in Nigeria to document the occurrence of grapevine viruses and viroids. A total of 318 leaf tissue samples were collected from different red and white fruited cultivars and tested in the laboratory. The presence of Grapevine leafroll-associated virus 1 (GLRaV-1) was detected based on various molecular analyses. This is thought to be the first report of GLRaV-1 infecting grapevine in Nigeria.
