SSR分子标记在烟草研究中的应用进展

Advance of the Application of SSR Molecular Markers in Tobacco Research

SSR分子标记技术作为最常用的分子标记技术之一,该标记技术重复性好,结果可靠,近年来在烟草遗传育种中展示了广阔的应用前景,是应用潜力较大的分子标记技术。介绍了SSR分子标记的原理及其分布特征,对其在烟草基因定位及分子标记辅助选择、种质资源研究、遗传图谱构建及种子纯度及真伪鉴定研究中的应用等方面进行了综述,并探讨了SSR分子标记技术在烟草遗传育种中的应用前景,以期为烟草SSR分子标记技术的研究提供参考。

SSR molecular marker technology as one of the most commonly used molecular markers, the marker technique result is reliable and good repeatability. In recent years, SSR marker shows a broad application prospect in tobacco genetic breeding, is a large potential for application of molecular markers. This paper introduced the principle and distribution characteristics of SSR molecular marker, and summarized the study of gene location and molecular marker-assisted selection, germplasm research, the construction of molecular genetic maps and the seed purity identification and authenticity of tobacco, and analysed the application prospect of molecular markers in tobacco genetic breeding. The main aim is to supply useful information so as to promote the development of SSR molecular marker technology research in tobacco.
