单核苷酸多态性及其在油菜分子标记辅助育种中的应用

Single Nucleotide Polymorphism and Its Applications in Marker-assisted Quality Breeding of Brassica napus L.

油菜是一种重要的油料作物,油菜的基因组功能研究已引起了各国政府和科研工作者的高度重视。SNP是目前为止分布最广泛,存在数量最多且标记密度最高的一种遗传多态性标记。对油菜等作物的基因组功能研究提供了丰富的信息资源。综述了近来单核苷酸多态性的研究进展以及其在油菜的分子标记辅助品质育种中的可能用途。

Brassica napus L. is a very important oil crop in the world. The functional genomics of Brassica napus L. has caught the attention and efforts of both the governments and the related scientists in the world. Single nucleotide polymorphism （SNP）is the most extensively distributed,most numerous and the highest density markers of genetic polymorphism to date. It provides rich informational resources for the functional genomics studies of many crops such as Brassica napus L.,among others. This review focused on the discussion of progress made in recently years and its possible applications in the research on molecular marker-assisted quality breeding of Brassica napus L.
