基于孤雌生殖诱导系的单倍体育种技术在玉米育种中被广泛应用，极大加快了育种进程。综述了玉米单倍体获得的途径和加倍的方法，讨论了孤雌生殖诱导系产生单倍体的机理以及单倍体的应用价值，最后分析了单倍体育种技术存在的问题，并对应用前景进行了展望。

The gynogenesis-inducer lines were used to induce maternal haploid, and this technology had been widely used in maize breeding, which accelerated the breeding process. The technology of haploid production and the methods of chromosome doubled in maize were introduced. Possible cause of the haploid-induce and the application of haploid in maize were discussed. Finally, we focused on some problems of haploid breeding, and haploid technology would become to a main method to select inbred lines in maize.
