    摘要:

    一年生簇毛麦(Dasypyrum villosum (L.) Candargy)是普通小麦野生近缘种之一,也是近年来应用较广泛的小麦遗传资源。簇毛麦在长期进化过程中,形成了许多可用于小麦遗传改良的重要农艺性状,包括对非生物和生物胁迫的抗性、优良品质等。本文简述了簇毛麦与普通小麦的同源关系、与小麦属杂交亲和性,以及将簇毛麦染色体、片段、基因导入普通小麦的有效方法,综述了簇毛麦对白粉病、纹枯病、条锈病、眼斑病、黄花叶病、全蚀病、胞囊线虫病等病害的抗性基因和对应的染色体,簇毛麦品质基因(如:高赖氨酸含量和多态性贮藏蛋白等)和簇毛麦耐旱、光周期等其他基因。介绍了簇毛麦抗白粉病基因Pm21PmV在小麦改良和育种中的应用及其巨大价值,展望了簇毛麦后续研究前景和可能存在的问题。本综述对挖掘与利用簇毛麦有益基因、拓宽小麦遗传资源、加快小麦遗传改良进程以及重要基因功能研究均具有参考价值。

    Abstract:

    Dasypyrum villosum (L.) Candargy is one of wild relatives of common wheat (Triticum aestivum L.). It is also the genetic resources for wheat improvement and has been widely used in recent years. In the long-term evolution process, D. villosum evolved many important agronomic traits, such as resistance to abiotic and biotic stresses, excellent quality, which are useful in wheat genetic improvement. This review paper briefly describes the homologous relationship between D. villosum and T. aestivum, the hybridization affinity with Triticum, and the effective methods for introgressing D. villosum chromosome disease,chromosome segments and genes into T. aestivum. The resistance genes of D. villosum to powdery mildew disease, sheath blight disease, stripe rust disease, eye spot disease, yellow mosaic disease, take-all disease, and cyst nematode disease on chromosome, the quality genes (such as : high lysine content and polymorphic storage protein, etc.), the drought tolerance, photoperiod and other genes were also reviewed. The application and great value of powdery mildew resistance genes of Pm21 and PmV in wheat improvement and breeding were introduced. The future research prospects and possible problems on D. villosum research were prospected.This review might provide reference for exploring and utilizing the beneficial genes of D. villosum, to broaden wheat genetic resources, accelerate the breeding process and functional investigation of important genes.
