FruitHealth - Full pathogen tests - Ribes

Pathogen tests for nuclear stocks - Ribes

Plants for testing are assessed in aphid-proof glasshouses for the following pathogens, prior to long term maintenance in a glasshouse under ‘high health’ conditions where plants are regularly re-checked for these pathogens.

Viruses detectable by mechanical inoculation of sap to test plants, including: Alfalfa mosaic virus, Arabis mosaic virus, Cucumber mosaic virus, Raspberry ringspot virus, Strawberry latent ringspot virus, Tomato black ring virus, Tomato ringspot virus, Tobacco ringspot virus and Tobacco rattle virus.

Viruses detectable by graft inoculation, including (a) Gooseberry vein banding as assessed by graft-inoculation tests to hybrid Ribes selection B1385/81 (VBI), (b) Blackcurrant reversion virus as assessed by graft-inoculation to Baldwin blackcurrant.

Symptoms of: Blackcurrant reversion, Blackcurrant yellows, Gooseberry/Blackcurrant veinbanding, Infectious variegation (gold dust) and Full blossom diseases.
