Abstract
The concentration of radish mosaic virus (RaMV) was investigated in leaves and in tuberous roots of turnir (Brassica rapa L. var. rapa). During the first 12. days of infection the virus multiplied in leaves relatively fast and the concentration soon reached a maximum; afterwards the concentration did not diminish, but remained at the same level for a very long time. Besides, the virus concentration was higher in old than in young leaves. The influence of RaMV on the yield of turnip was very great so that the tuberous roots of infected plants were reduced in size.
The transmission of the virus through seed could not be detected in the following cruciferous species: Brassica rapa L. var. rapa, Capsella bursa pastoris (L.) Med., Sinapis alba L. and S. arvensis L.
