摘要
In recent years,with the continuous improvement and development of molecular technology in the application process,different types of DNA molecular markers have made rapid progress in the study of genetic diversity of rapeseed. The study of genetic diversity is conducive to the correct formulation of the strategy of collecting and in situ preservation of genetic resources of rapeseed,and it is the genetic basis for the improvement of rapeseed varieties. This article mainly starts with the three DNA molecular markers( SSR,RAPD,AFLP) widely used in the study of genetic diversity of rapeseed. By introducing the application principles and characteristics of SSR,RFPD and AFLP molecular markers,research progress of these three marker technologies in genetic diversity of rapeseed is briefly described.
