The protection of intellectual property relating to the agricultural and biotechnical industries could be realized through the use of patents, trade secrets, plant seedlings, copyrights, and trademarks. Particularly, the plant species and seedling method provides direct protection on the benefits of new species. The DUS test on new species is the most important reference for the approval of new species. The DUS test's quality also influences the conduct of statutory implementation. In relation to this, the current paper mainly uses the Plant Species Protection and Training Course held in Holland in 2007 as reference. Some concepts and trends for the species test are as follows: the concept of substantial derivative species, the species test system, a brief introduction on the test plan's planning procedure, and the species test's certification.
