New races with wider virulence indicate local evolution of <i>Puccinia striiformis</i> f. sp. <i>tritici</i> in South America

2023-10-25

Abstract excerpt

Wheat yellow (stripe) rust, caused by Puccinia striiformis f. sp. tritici ( Pst ), is one of the most devastating diseases of wheat worldwide. Pst populations are composed of multiple genetic groups, each carrying one or more races characterized by different avirulence/virulence combinations. Since the severe epidemics in 2017, yellow rust has become the most economically important wheat foliar disease in Urug...
