<i>Aegilops tauschii</i> is one of the malignant weeds that affect wheat production and is also the wild species ancestor of the D genome of hexaploid wheat (<i>Triticum aestivum</i>, AABBDD). It contains many disease resistance genes that have been lost in the long-term evolution of wheat and is an important genetic resource for the mining and utilization of wheat disease resistance genes. In recent years, the genome sequence of <i>Aegilops tauschii</i> has been preliminarily completed, which has laid a good foundation for the further exploration of wheat disease resistance genes in <i>Aegilops tauschii</i>. There are many studies on disease resistance genes in <i>Aegilops tauschii</i>; in order to provide better help for the disease resistance breeding of wheat, this paper analyzes and reviews the relationship between <i>Aegilops tauschii</i> and wheat, the research progress of <i>Aegilops tauschii</i>, the discovery of disease resistance genes from <i>Aegilops tauschii</i>, and the application of disease resistance genes from <i>Aegilops tauschii</i> to modern wheat breeding, providing a reference for the further exploration and utilization of <i>Aegilops tauschii</i> in wheat disease resistance breeding.
