Other claims from this paper (7)
- Observation Mean virulence complexity per isolate increased in the contemporary Bgt population.
- Observation Overall pathotype diversity of the Bgt population decreased.
- Observation Efficacy of Pm1a eroded severely, with virulence increasing from 6 to 63%.
- Observation Efficacy of Pm8 also eroded severely.
- Observation Virulence against Pm2, Pm3a and Pm3b declined significantly.
- Observation Genes Pm2 and Pm4a showed complete and durable effectiveness throughout the study period.
- Recommendation Pm2 and Pm4a are identified as stable resistance donors; the authors recommend them for durable resistance gene pyramids and continuous virulence surveillance.
