The challenge
Genetic resistance is a useful tool for disease control but if the pathogen adapts to the resistance mechanism, causing breakdown of the resistance, previously resistant varieties become susceptible. The risk of this happening is higher in varieties that rely on single major genes for resistance or those where combinations of race-specific genes that have already been matched individually by virulence in the pathogen are used. This can result in widespread damaging disease epidemics.
The project
The project aims to monitor changes in virulence of rust and mildew populations and determine their significance for the resistances that are being used in current varieties and breeding programmes.
The benefits
Continued improvement of genetic resistance, which will reduce the dependence on fungicides and lead to environmental and economic benefits.
*This project has had several phases. The current phase started in April 2019 and is jointly funded by Defra and AHDB. The AHDB cost presented is associated with the current phase.
UKCPVS focus for harvest 2024
For harvest 2024, the UKCPVS project has been refined to make the work even more relevant to levy payers. For example:
- The project will pathotype four isolates of barley powdery mildew on RL spring barley varieties (not candidates), following unusual observations of this disease in RL trials in 2022 and 2023
- In 2023, the project piloted a faster method to generate young-plant-resistance data for wheat yellow rust on an RL variety subset. In 2024, all RL winter wheat varieties (including candidates) and a reduced differential set will be tested with 10 to 25 isolates
- UKCPVS will also pilot a method to test a mix of yellow rust isolates, which will be compared to the single isolate tests
- The number of brown rust isolates tested will be reduced to a maximum of 10
- Adult plant trials will not be carried out in 2024
- The reduced testing mentioned in the previous two points will free up resource to increase testing mentioned in the first three points
