通过小麦与玉米远缘杂交诱导小麦单倍体,经染色体人工加倍后第一代即可获得纯合稳定的加倍单倍体DH系,与花药培养获得的DH系相比,具有不受小麦基因型差异的影响、没有无性系变异发生等优点,因此在小麦的遗传研究和育种实践中具有重要意义。对小麦×玉米诱导单倍体胚的研究已有 The wheat haploid was induced by distant crosses between wheat and maize, and the homozygous stable doubled haploid DH line could be obtained by the first generation after chromosome doubling. Compared with DH line obtained from anther culture, Type differences, there is no clonal variation occurs, etc. Therefore, in the genetic research of wheat and breeding practice is of great significance. Research on haploid embryos induced by wheat × corn has been done
