UK Cereal Pathogen Virulence Survey (UKCPVS)

The UK Cereal Pathogen Virulence Survey (UKCPVS) uses pathogen isolates from infected cereal leaf samples to check which varieties they can infect. The tests can help detect new races of wheat and barley pathogens capable of causing disease on previously resistant cereal varieties.

UKCPVS facts

Monitors changes in pathogen virulence (wheat and barley)
Funded by AHDB and Defra
Managed by NIAB
First report published in 1967
Samples provided by agronomists, trials officers and researchers

How to submit a leaf sample for testing

The success of UKCPVS depends on infected cereal leaf samples received from the field, if you would like to get involved, full sampling instructions are available from the niab website.

Young-plant resistance to yellow rust

The pathogen that causes yellow rust – Puccinia striiformis f. sp. tritici – comes in different forms. There are races that only infect particular varieties. To add further complexity, some varieties are susceptible to yellow rust when plants are young, but go on to develop some level of resistance after early stem extension (the ‘adult-plant’ stage).

UKCPVS Stakeholder Event

Targeted at breeders, crop scientists and technical agronomists, the annual stakeholder event reports on recent seedling test results and adult plant nursery tests. It also features related technical papers based on pathogen virulence experience from across the globe.

UKCPVS news

‘Interesting’ wheat yellow rust isolates identified by UKCPVS (March 2021) Variety ‘watch list’ for wheat yellow rust released (January 2021) Shake-up for RL wheat rust ratings and latest UKCPVS data (November 2020) Wanted: yellow and brown rust samples for UKCPVS (April 2020) New pathotypes add further complexity to wheat rust population (March 2020) Early release of wheat rust resistance ratings (October 2019) ‘Calm’ 2018 provides time to reflect on cereal pathogen populations (January 2019)

Coronavirus statement

As usual, UKCPVS plans to process all samples received. In addition to the standard sampling protocol, please ensure you adhere to government coronavirus guidelines when collecting and submitting samples: gov.uk/coronavirus

The first 50 years

In 1967, the coordinated monitoring of cereal pathogen populations in the UK began.
