In the German Democratic Republic both wild mazzard cherries and those grown for seed production were infected by cherry ringspot viruses, although the extent of attack differed. The degree of infection depended on the source, location and age of the tree. Cherry chlorotic-necrotic ringspot virus was the most common, sometimes occurring as a mixed infection with cherry chlorotic ringspot virus. The cherry necrotic ringspot virus was found only occasionally.
