An undescribed spherical virus ca. 25nm in diameter that showed systemic necrotic symptoms to Chenopodium quinoa was isolated from Prunus mume. The virus had a reratively wide host range and had a reratively stable in crude sap. Purified virus preparations containd two RNA components and the protein similar to coat protein of Cycas necrotic stunt virus (CNSV). Its nucleotide sequence of the coat protein gene had 89% common identity with that of CNSV isolated from Cycas revoluta. Also, ‘nishiki-sei’ that a feature of several variety of Prunus mume show yellow blotches on branch, it is likely that the ‘nishiki-sei’ is caused by the CNSV infection.
