| 中文摘要: |
| 野生近缘种是小麦遗传改良的基因资源库，远缘杂交有助于丰富小麦遗传多样性，培育优异新种质。滨麦（Leymus mollis, NsNsXmXm,2n=4x=28）是隶属于赖草属的一个多年生自交不亲和物种，具有抗寒旱、耐盐碱、抗真菌病害等诸多优良特性。本文主要介绍了滨麦染色体组成，汇总了目前已报道的38个小麦-滨麦异染色体导入系，对异源染色体导入系的鉴定方法及滨麦遗传物质导入对受体小麦主要农艺性状和品质的影响进行了综述，并对小麦-滨麦染色体导入系的未来研究与应用进行了展望，以期为进一步挖掘和利用滨麦优异基因，促进小麦种质创新和遗传改良提供参考。 |
| 英文摘要: |
| Wild relatives are the gene pools for wheat genetic improvement. Distant hybridization helps to enrich the genetic diversity of wheat and cultivate excellent new germplasm. Leymus mollis(NsNsXmXm, 2n=4x=28) is a perennial self-incompatible species belonging to the Leymus genus, named for its growth in coastal areas. Many excellent characteristics of Leymus mollis, such as cold and drought resistance, salt and alkali tolerance, and resistance to fungal diseases, can be transferred to common wheat through distant hybridization. This paper mainly introduces the composition of the Leymus mollis genome, summarizes the 38 wheat-Leymus introgression lines that have been created, describes the identification methods of the alien chromosome introgression lines, and discusses the impact of the introduction of Leymus mollis genetic materials into the wheat background on the main agronomic traits and quality of the recipient. Finally, the future applications of wheat-Leymus mollis chromosome introgression lines are prospected, to help the researchers further understand and utilize Leymus mollis, excavate its excellent genes, and promote the improvement and innovation of wheat germplasm resources. |
