Peach enation, a new virus disease of peach was discovered on the variety Shinsei. The infected trees showed many small enations on the undersurface of leaves as well as shortening of internodes. A mechanically transmissible virus was isolated from the diseased peach trees to Chenopodium quinoa. This virus was transmitted from C. quinoa to C. amaranticolor, C. album, Vinca rosea, Gomphrena globosa, Celosia cristata, Tetragonia expansa, Zinnia elegans, Raphanus sativus, Crotalaria spectabilis, Phaseolus angularis, Vigna sesquipedalis, Sesamum indicum, Torenia fournieri, Nicotiana glutinosa, N megalosiphon, N tabacum, Petunia hybrida and Physalis floridana. The virus could be retransmitted from C. quinoa to peach seedlings by inarch grafting, and the affected seedlings showed the same symptoms as those of the original diseased trees. The virus was spherical and approximately 33 nm in diameter. In crude sap of infected C. quinoa, the thermal inactivation point was 50-60C, 10 minutes, dilution end point was 10^<-4>-10^<-5> and longevity was 30-40 days. The virus was neither transmitted by Myzus persicae nor by Aphis gossypii and no evidence of soil borne was obtained. The liter of the antisera prepared from the infected C. quinoa was 1,280. This antiserum did not react with arabis mosaic virus, cherry leaf roll virus and strawberry latent ringspot virus and also the antisera of raspberry ringspot virus, arabis mosaic virus and tomato black ring virus did not react with this virus. These results indicated that this virus is a new one not yet being reported. It was named peach enation virus.
