SUMMARY A virus, code‐named 52V, was obtained from 16 cultivars and seedlings of red raspberry by inoculation of sap to Chenopodium quinoa during spring or autumn. Some raspberry plants were infected with 52V after six months in the field, and more than 50 per cent of the plants of some cultivars were infected after four years. The virus was also obtained from Rubus occidentalis plants previously infected with virus from red raspberry by means of aphids ( Amphorophora rubi and Aulacorthum solani ). These aphids transmitted 52V from red raspberry to C. quinoa . 52V was transmitted by inoculation of sap to six herbaceous species but induced symptoms only in Chenopodiaceae. In C. quinoa sap, 52V lost infectivity after dilution to 10 −2 , heating for 10 min at 52·5°C, storage at 18°C for 24 hr or treatment with n ‐butanol to 8·5 per cent (v/v). Preparations made by clarifying extracts with chloroform or ether followed by differential centrifugation contained a few isometric particles c . 30 nm in diameter which may be those of the virus.
