Strengthen Plant New Variety DUS Testing Techniques and Research on Genetic Resources Management and Application of the Potential Crops in Taiwan

(a)Strengthening DUS Testing Techniques and Promotion and Arrangement in Accordance with Plant Variety Rights

The project is to establish the test guidelines and execute DUS tests and modified the test guideline and table of characteristics of nephrolepidaceae and graptopetalum and the agapanthus initial characteristics’ table has been established and included 31 tems. TSIPS also collected 60 commercial varieties of phalaenopsis and doritaenopsis for establishing variety database. TSIPS have accepted 74 cases of phalaenopsis , 2 cases of oncidium and 6 cases of rose to execute DUS tests for protecting the breeder’s rights this year. There are 10 cases of phalaenopsis and doritaenopsis have been executing DUS tests, and 46 phalaenopsis and, 10 oncidium and 3 rose cases have been granted PBR. We also have finished a plant variety DUS testing technique training seminar on November in 2020.
