小麦育种的一个重要研究领域就是将小麦亲缘属的有益基因引入小麦,改良小麦品种,簇毛麦(Haynalia villosa,2n=14)就是小麦的一个重要亲缘属。它分蘖旺盛,对小麦条锈、叶锈和杆锈均免疫,对全蚀病和白粉病的抗性亦很强,是一个值得重视的抗源。但是,六倍体的通小麦与簇毛麦的属间杂交十分困难,获得的杂交种子极少。近年来,随着 An important field of wheat breeding is the introduction of genetically favorable wheat-related genes into wheat, improved wheat varieties, Haynalia villosa (2n = 14) is an important relatives of wheat. It has strong tillering, immunity to wheat stripe rust, leaf rust and stem rust, and is also very resistant to total eclipse and powdery mildew, which is a worthy source of resistance. However, the crosses between hexaploid to wheat and cluster wool were very difficult and very few hybrid seeds were obtained. In recent years, with
