A dominant wheat stripe rust resistance gene, temporarily designated as YrY201, was identified in an accession Y201 of Aegilops tauschii. By bulk segregation analysis, three microsatellite markers Xgwm273b, Xgwm37 and Wmc14 were found to be linked to YrY201 with genetic distance of 11.5, 5.8 and 10.9 cM , respectively. According to the locations of the linked markers, the resistance gene was located on chromosome 7DL. Based on the chromosomal location and the resistance pattern of the gene, we proposed that YrY201 was a novel stripe rust resistance gene, and could be selected by marker-assisted selection.
