| Abstract: | The presence of rod-shaped viruses in German hops has been known for a long time and Hop Mosaic Virus (HMV) and Hop Latent Virus (HLV) were proved to be present by serological techniques. When another CARLA-Virus, the American Hop Latent Virus was detected in England an extensive survey was carried out in the German hop growing regions and among wild hops. No natural occurrence of the virus could be detected. Only recently introduced plants of the American clone USDA 21055 in an isolated breeding garden were infected. Spread of the virus to German seedlings could not be detected. |
