Collection of Hop Pathogens


•    History
The collection was established in 2003. The main attention is paid to hop pathogens - viruses and viroids.

•    Characterization of collection
8 virus isolates
1 fungus isolate

•    Methods of culture maintenance
infected hop plant, CaCl2, lyophilization

Each year monitoring is performed pathogens control by ELISA and RT-PCR, the same time there is a continuous obtaining of new isolates
Isolates: ApMV, ArMV, HLV, HMV, HLVd


Diagnosis of pathogens - ELISA, PCR, phytopathological – virology

Utilization of strains
positive controls for testing of nursery material
providing of strains for research
