Abstract excerpt

Stripe rust of wheat, caused by Puccinia striiformis f. sp. tritici (Pst) remains a major threat to global wheat production. In Canada, long-term collection of Pst isolates since 1984 provides a unique perspective on pathogen evolution over four decades. This study extends previous race structure analyses by characterizing 73 isolates collected since 2020 from wheat, barley, and wild barley. Among 56...
