In 1995, we collected stock (Matthiola incana) plants causing mosaic symptoms on leaves and color breakings on flowers in Daekwallyong, Korea. Two viruses were isolated from the infected plants, and identified as cucumber mosaic virus (CMV) and turnip mosaic virus (TuMV) by experiments of host range, serology and electorn microscopy. Each of the virus did not produce the same symptoms on the stock seedlings as naturally infected plants caused. When the viruses were coinoculated to the stock seedlings, however, severe mosaic symptoms were observed on leaves, and then the color breakings were expressed on flowers.
