Survey on the Occurrence of Five Grapevine Viruses in Korean Vineyards in 2021

Abstract

In this study, a total of 217 samples were collected from five grapevine cultivars in Chungcheongbuk-do and Gyeongsangbuk-do in 2021. These samples were tested for the presence of five grapevine viruses using specific primers through polymerase chain reaction. The results indicated that grapevine fleck virus was confirmed in 126 samples (58.06%), grapevine leafroll-associated virus (GLRaV)-3 in 112 samples (51.61%) and GLRaV-1 in four samples (1.84%). The infection rate was high in Shine Muscat and Alexandria cultivars, and by region, the Gyeongbuk region showed a high infection rate. However, the presence of grapevine red blotch associated virus and grapevine berry inner necrosis virus were not detected.
