Grapevine Pinot gris virus infecting grapevines in Romania - Short Communicaiton

Grapevine Pinot gris virus (GPGV) has been identified in many grape growing countries of the world since 2012. The aim this work was to investigate presence GPGV on some accessions collected from a germplasm collection, addition propagation material and clonal selection samples. During 2019–2020, total 199 samples have analysed by double antibody sandwich – enzyme-linked immunosorbent assay (DAS-ELISA) for GPGV, fanleaf (GFLV), leafroll-associated virus-1+3 (GLRaV-1+3) fleck (GFkV). Among them, 107 (53.76%) showed GPGV-infection, associated with or without symptoms leaves (deformations, chlorosis, mosaic, wrinkles) stunting plants. distribution infected varieties high rate infection old (37.38%), followed clones (32.71%), rootstocks (11.21%), selections (9.35%) new (9.35%). tests revealed association GFkV (5 cases) GLRaV-1+3 (2 cases). should be included rules grapevine certification schemes production virus-free mother
