Introduce the basic conception of variety management，and the application pattern of molecular marker technology in variety testing. On the basis of the analysis and discussion，we get two conclusions：（1）The molecular marker technology can not be the gist for variety judgment independent，it should be combined with the phenotypic observation；（2）The application of molecular marker technology in breeding will reinforce its application in variety testing. At the same time，we propose 5 relevant policy suggestions in order to promote the application of molecular marker technology in variety management.
