DUS Test Guidelines are not only the technical manuals for the DUS testing authorities to conduct the testing, but also the technical standards for the competent authorities to examine the DUS of new varieties of plants. Tea plant, which is originated from China, is a very important woody cash species in the world. UPOV (International Union for the Protection of New Varieties of Plants) DUS Test Guidelines for tea plant is the first DUS Test Guidelines prepared by China for the UPOV. In this paper, the subject, selection and adoption of characteristics, states of expression and selection of example varieties, assessment of DUS of the UPOV Test Guidelines for tea plant were elucidated in detail. Finally, proposals for PVP of tea plant in China was also proposed. The preparation of UPOV DUS Test Guidelines for tea plant will have important significance both for promoting the development of PVP and increasing the status of international PVP fields for China. Key words: International Union for the Protection of New Varieties of Plants (UPOV); Plant variety protection (PVP); Tea plant [Camellia sinensis (L.) O.
