SUMMARY The elm mosaic and golden elderberry strains of cherry leaf roll virus (CLRV) and a strain from cherry and from rhubarb were very similar in their host range, symptomatology and properties in vitro. However, only the rhubarb isolate infected rhubarb systemically and only the golden elderberry isolate infected Sambucus nigra systemically. Purified preparations of all strains contained isometric particles which sedimented as two nucleoprotein components with sedimentation coefficients of about 115 S and 128 S. The elm mosaic strain was the least stable in vitro and was the most difficult to purify. In plant‐protection tests, one‐way protection occurred between tomato ringspot virus and each of the four CLRV strains. However, whereas the elm mosaic, golden elderberry and the cherry strains protected against one another, they did not protect against infection with the rhubarb strain.
