Narcissus viruses occurring in China
In recent years the substantial narcissus production in China suffered yield and quality losses due to virus infections of the plants. To investigate the causal agents of the virus infections and to determine the range of infection a survey was carried out in the most affected province of Fujian. As reported at the 6th International Congress of Plant Pathology in Montreal, 7 viruses were found in field collected narcissus plants. They were narcissus latent carlavirus, narcissus mosaic potexvirus, narcissus yellow stripe potyvirus, cucumber mosaic cucumovirus, potato Y potyvirus, tobacco mosaic tobamovirus and tobacco rattle tobravirus. Several plants showed multiple infections by several viruses and the incidence of virus infection in the field reached up to 100%.
