Resistance to wheat 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 at the seedling stage, but go on to develop some level of resistance after early stem extension (the ‘adult-plant’ stage).

This page provides the resistance status of wheat for both stages – seedling and adult. However, the yellow rust population is highly diverse and changeable. It is important that crops are monitored regularly and unexpected disease observations reported to the UK Cereal Pathogen Virulence Survey (UKCPVS).



How yellow rust seedling-stage resistance is determined

  • Seedling resistance is categorised using five isolates, selected by UKCPVS, to best represent the diversity in the yellow rust population at the time of testing
  • A variety is classified as seedling susceptible if it is susceptible to any one of the isolates
  • The adult plant resistance presented in the table is based upon the Recommended Lists (RL) yellow rust disease ratings for 2020/21, which were calculated in 2019
  • Status is presented for recommended and candidate varieties in trial (it does not feature varieties no longer under test in RL trials) 
  • As pathogen populations are diverse and can change rapidly, so can resistance status
  • As isolates chosen for testing are a subset of the population, actual field performance may vary
