族毛麦基因组及其在小麦改良中的应用研究进展

簇毛麦是小麦的近缘属，是小麦改良重要的基因资源。簇毛麦有益基因向小麦遗传背景的导入，主要利用小麦－簇毛麦双二倍体为桥梁亲本，通过杂交、回交等方式获得小麦异代换系、异附加系、异易位系；并且利用形态标记、细胞学标记、生化标记及分子标记对小麦遗传背景下的染色体组、染色体、染色体臂及片段进行鉴定。本文对这些方面的研究进展进行了综述，对族毛麦可利用基因进行了展望。

Advance of Study on D.villosum(H.villosa ) Genome and Its Application in Wheat Improvement

D.villosum (H.villosa) , which is the relative genus of Triticum, was the important resources for wheat improvement. The favorable genes from D.villosum (H.villosa) were introduced into wheat genetic background through cross and backcross using double diploid as parent. The alien addition lines, alien substitution lines, and alien translocation lines were obtained. By aid of morphologic, cytological, biochemical, and molecular markers, the genome, chromosomes, arms and fragments of chromosomes were identified in wheat genetic background. The disease resistance genes had been applied in wheat improvement. Many other genes, such as drought resistance genes, saline resistance genes and high protein content genes would be explored in the future.
