Doubled haploid (DH) technology is a biotechnology that rapidly obtains homozygous plants through haploid induction and chromosome doubling, genetic stability in one generation and significantly shortening the breeding cycle. It is widely used in the genetic breeding of various crops such as wheat, corn, and rapeseed, especially a key role in the construction of genetic populations, QTL mapping, and variety improvement. This paper will briefly introduce the method of producing wheat haploid, review the latest progress of DH breeding technology in the field of wheat research, and introduce the application examples of DH technology in accelerating breeding, genetic map construction, nuclear sterility, and microspore genetic transformation, in order to promote the development of DH technology in wheat breeding and further improve the efficiency of wheat breeding.
