摘　　要：苦苣苔科报春苣苔属具有极其丰富的生物多样性,大多数都具有极高的观赏价值,而其多样化的花朵、叶片和植株形态使其具有开发为极具我国特色的新花卉的潜力。近年来,国产苦苣苔科植物,尤其是报春苣苔属越来越受到人们的重视,在世界苦苣苔科植物新品种登录权威——世界苦苣苔协会(The Gesneriad Society,GS)进行登录的报春苣苔属新品种日渐增多,而该属也有望得以被我国农业农村部新品种保护办公室列入植物品种保护名录。但是目前报春苣苔属植物在国内外均无相关的DUS测试指南与标准,这方面的工作亟待开展。因此,本研究根据植物新品种特异性、一致性和稳定性(简称DUS)测试的原理和技术规则,参考UPOV关于同科不同属的、源自不同国家的测试指南,结合资源现状,研制适用于我国报春苣苔属植物新品种测试的指南,对其适用对象、性状的选择与确定、性状分级、标准品种的选用和DUS判定标准进行详细研讨,为报春苣苔属植物新品种的授权提供测试技术的支撑,为极具我国特色的该类植物测试技术规程的建设与完善提供参考,为将这一类群的新品种培育、园艺化、产业化和新品种保护提供行业标准。The species of the genus Primulina of Gesneriaceae are abundance in biodiversity,and most of them have high ornamental value.Those diversified flowers,leaves and plants of this group hint that they can be developed as one group of new ornamental crops,which rich in Chinese characteristics.Those domestic Gesneriaceae plants,especially in Primulina,are gaining more attentions in recent years.There are more and more new artificially bred ornamental cultivars of this genus were registered in the Gesneriad Society(GS),which is the international registration authority for Gesneriaceae cultivars.In the near future,this genus is expected to be listed in the list of Protection of New Varieties of Plants by the Ministry of Agriculture office for the Protection of New Varieties of Plants.However,there is no related DUS test guideline for Primulina plants in both China and abroad.It is urgent to develop the test for Primulina.Thus,according to the testing theory and technology of distinctness,uniformity and stability of new varieties of plants,based on the resources in and abroad and UPOV guidelines of different genera from different countries in Gesneriaceae and resource situation,the subject,selection and adoption of characteristics,states of expression and selection of standard varieties,assessment of DUS of the Testing Guidelines for Primulina,were elucidated in detail in this paper.The DUS test guidelines for Primulina will provide technology structure for this kind of new variety and offer professional standard for the new variety cultivation,horticulture,industrialization and plant variety protection of this group.
