Jersey and Berkley highbush blueberry cultivars that had been planted as rooted cuttings in 1975 beneath a canopy of Concord grapevines infected with peach rosette mosaic virus were indexed positive for the virus on Chenopodium quinoa in 1978. Two years later, symptoms appeared on Jersey bushes as elongated, strap-shaped or as malformed, crescent-shaped leaves on portions of the bushes; on Berkley bushes, several of the terminal leaves were spoon shaped.
