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

以国际植物新品种保护联盟(UPOV)制定的植物新品种DUS(distinctness, uniformity and stability)测试指南总则(TG/1/3)、箭筈豌豆DUS测试指南(TG/32/7)等技术文件为指导,对箭筈豌豆DUS测试指南的核心技术内容:测试性状和参照品种等开展...以国际植物新品种保护联盟(UPOV)制定的植物新品种DUS(distinctness, uniformity and stability)测试指南总则(TG/1/3)、箭筈豌豆DUS测试指南(TG/32/7)等技术文件为指导,对箭筈豌豆DUS测试指南的核心技术内容:测试性状和参照品种等开展了研究。在国内外共收集到51个箭筈豌豆品种,并进行连续2年的田间观测。观测性状总计31个,包括UPOV箭筈豌豆DUS测试指南中的23个性状,以及本实验发现有特异性的8个新增性状。对每个测试性状的表达状态、观测时期、测定方法、观测数量等进行了分级和详尽描述。共筛选出32个参照品种(国际21个,我国11个),确定了123个表达状态。并对UPOV箭筈豌豆DUS测试指南中"外种皮底色"和"种子形状"表达状态的分级进行了补充。本研究结果可为我国箭筈豌豆新品种DUS测试指南的制定奠定技术基础,对促进我国箭筈豌豆品种保护、审定和育种工作具有重要的意义。展开更多
