摘　　要：兜兰属(Paphiopedilum)植物种质资源丰富,具有较大的育种潜力和广阔的产业前景。但目前国际植物新品种保护联盟(UPOV)、日本及中国均无兜兰属特异性、一致性和稳定性(DUS)测试指南。本研究中结合中国兜兰属植物资源状况、育种现状和产业发展水平,按照中国相关国家标准,收集并测试了兜兰属56份材料,确定64个测试性状,包括37个基本性状和27个选测性状,以及5个分组性状和11个标准品种。Paphiopedilum is a genus of high ornamental value,recognized as a high-grade flower in the international flower market.The genus is rich in germplasm resources,with considerable breeding potential and broad industrial prospects.However,guidelines for the DUS(Distinctness,Uniformity and Stability)test of Paphiopedilum are not available in UPOV(International Union for the Protection of New Varieties of Plants),Japan or China.According to the relevant national standards in China and considering the status of Paphiopedilum resources,breeding advancements,and the current level of industrial development,56 Paphiopedilum materials were gathered and tested.A total of 64 test characteristics were identified,including 37 basic characteristics and 27 optional characteristics,as well as 5 grouping characteristics and 11 standard cultivars.
