Abstract  Psathyrostachys huashanica (2n=2x=14, NsNs) is one of the wild relatives of wheat (Triticum aesivum). It has excellent characteristics such as resistance to various wheat diseases, cold and drought tolerance, high quality and early maturity. It has important utilization value for broadening the genetic basis of wheat and creating new germplasm. This article focuses on the wheat-P. huashanica chromosome introgression lines; summarizes the various types of wheat-P. huashanica derived lines that have been created in recent years; and summarizes the common identification methods of P. huashanica chromosome homologous groups in wheat background. The Oligo probes applicable in the fluorescence in situ hybridization experiments were listed, and the available expressed sequences tags-sequencetagged sites (EST-STS), simple sequence repeats (SSR), sequence characterized amplified region (SCAR), PCR-based landmark unique gene (PLUG), and kompetitive allele-specific PCR (KASP) molecular markers were sorted out according to the homologous groups. In addition, the effects of genetic material introgression of P. huashanica on the resistance of receptor wheat to powdery mildew, stripe rust, take-all and other diseases, as well as agronomic traits such as plant height, 1 000-grain weight and tiller number were analyzed. Finally, the application of P. huashanica in wheat breeding was prospected, in order to provide reference for the application of P. huashanica in wheat genetic breeding.
