ABSTRACT Stem rust, caused by Puccinia graminis f. sp. tritici (Pgt), remains a significant threat to global wheat production, as new races overcoming deployed resistance genes continue to emerge rapidly. In 2011, the Australian rust surveillance programme detected a new pathotype 34‐1,2,5,7 virulent on stem rust resistance genes Sr5 , Sr6 , Sr7b , Sr9g , Sr11 , Sr15 and Sr17 . Although virulent on Sr11 , this pathotype produced a low infection type (IT 22+c to X) on the Sr11 ‐differential genot
