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, originated from Yunnan Province, China, is a very important woody cash species in the world. The International Union for the Protection of New Varieties of Plants （UPOV） DUS Test Guidelines for tea plant is the first Test Guidelines prepared by China for the UPOV. In this article, the subject, selection, and determination of characteristics, states of expression of characteristics and the selection of example varieties, assessment of the UPOV DUS Test Guidelines for tea plant were elucidated in detail. Finally, the proposal of PVP for 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.展开更多

The strongest predictors of relationship status found were interactions between bi-nary variables for the age that a respondent first had sexual intercourse and for the age that a respondent first entered into a union (N = 1452). This paper con-cludes by arguing that the results provide support for viewing union status as being primarily dependent on the people involved in the union instead of being primarily dependent on factors external to the people themselves.展开更多
