Abstract: 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.

Key words: tobacco, molecular marker, SSR, genetic breeding
