Interpretive Summary: This paper is the first report on two unique grapevine rupestris stem-pitting-associated virus (GRSPaV) variants found in Idaho ‘Riesling’ grapevines. How this grapevine virus might alter grape quality is not yet known, so further study is required. As some grapevine viruses do not significantly impact quality, determining a vine’s virus status is crucial in formulating appropriate viticultural and enological strategies for mitigating virus infections, especially in working vineyards where replacing large numbers of vines is not economically feasible.

Technical Abstract: We report the genome sequences for two genetic variants of grapevine rupestris stem-pitting-associated virus (GRSPaV) from Idaho, USA. The coding-complete, positive-strand RNA genome of 8,700-nt encodes six open reading frames characteristic of foveaviruses. The two Idaho genetic variants belong to phylogroup 1 of GRSPaV.
