粗山羊草在小麦遗传育种中的应用研究进展

小麦是世界上第二大粮食作物,对我国粮食供给起到举足轻重的作用。但目前高产、抗病及抗逆性强的小麦品种较少,使小麦的生产受到一定制约。挖掘优异遗传资源,培育高产、优质、抗逆性强的小麦品种是小麦育种的重要任务。粗山羊草是小麦D基因组的供体,蕴含着大量抗病、抗虫、抗逆和改良小麦品质的基因。为挖掘其优异基因用于小麦育种,丰富小麦的遗传资源,对小麦育种工作起到推动或借鉴作用,对粗山羊草在分子水平和抗病、抗虫、抗逆方面的研究进展进行综述,介绍了在储藏蛋白方面的研究情况,以及粗山羊草在小麦育种上的应用。

Research advances in application of Aegilops tauschii on wheat genetics and breeding

Wheat is the second major grain crops in the world and plays a pivotal role on food supply in China.Wheat species of high yielding, strong disease and stress resistance are still rare at present, so wheat production is under certain constraints.Searching the excellent genetic resources to breed wheat variety with high yield, good quality, strong resistance is an important task for wheat breeding.Aegilops tauschii is the donor of D genome in wheat and contains a large number of genes of disease resistance, insect resistance, stress tolerance and wheat quality improvement.Finding out its excellent genes for the wheat breeding could undoubtedly enrich wheat genetic resources, promote and provide reference for the wheat breeding work.The study reviews the progress of researches on Aegilops Tauschii in terms of its molecule level, disease, insect and stress resistance, the research in protein storage and the application of Aegilops tauschii on wheat breeding.
