This manuscript describes the chromosomal location of a new source of stripe rust resistance in wheat. DNA markers closely linked with the resistance locus were identified and validated. A wheat landrace, AUS27858, from the Watkins collection showed high levels of resistance against Australian pathotypes of Puccinia striiformis f. sp. tritici. It was reported to carry two genes for stripe rust resistance, tentatively named YrAW1 and YrAW2.
