红花新品种DUS测试指南的制订

植物新品种特异性(distinctness)、一致性(uniformity)和稳定性(Stability)(简称DUS)测试是新品种保护的技术基础和授权的科学依据。DUS测试指南既是指导测试机构开展DUS测试工作的技术手册，同时还是审批机关审查新品种DUS的技术标准。红花（Carthamus tinctorius L.）俗称草红花或杜红花，是一种油、药及工业多用途作物，其经济价值较高。本文详细地论述了红花DUS测试指南的适用对象、测试性状的选择与确定、性状分级与标准品种的选用、红花DUS判定标准的确定。红花DUS测试指南的制订对增强红花新品种保护，促进我国植物新品种保护事业的发展具有积极意义。

Establishment of Distinctness, Uniformity and Stabilit Testing Guidelines for Carthamus tinctorius L.

Distinctness, Uniformity and Stability （DUS for short） 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. Safflower is a traditional Chinese medicinal plant as well as a new oil and industrial crop. This paper reviewed safflower’s states selection, expression and selection of example varieties, based on the UPOV DUS Test Guidelines for safflower. The preparation of DUS Test Guidelines for safflower will have important significance both for promoting the development of PVP and increasing the status of international PVP fields for China.
