摘要: 为促进麦冬[Ophiopogon japonicus(L.f.)Ker-Gawl.]植物新品种保护,从源头推动原产中国的麦冬种质资源的利用与发展,并促进地方特色中药材麦冬产业的发展,开展了麦冬品种特异性、一致性和稳定性(简称DUS)测试指南的制定研究。通过种植观测93份麦冬类种质资源,研究了麦冬的栽培、繁殖方法和表型数据采集方法,筛选出27个性状用于麦冬品种的表型描述,明确了麦冬品种DUS测试对繁殖材料的要求,规定了麦冬DUS判定的一般原则,制定了麦冬DUS测试指南。

Abstract: In order to promote the protection of new varieties of Ophiopogon japonicus, utilization and development of its germplasm resources originated in China, as well as the development of local characteristic medicinal Ophiopogon japonicus industry, the research on the formulation of the distinctness, uniformity and stability (DUS) test guide of Ophiopogon japonicus varieties was carried out. By planting and observing 93 accessions of Ophiopogon japonicus germplasm resources, the cultivation, propagation methods and phenotypic data collection methods of Ophiopogon japonicus were studied, 27 traits were selected for phenotypic description of Ophiopogon japonicus varieties, the requirements for breeding materials for Ophiopogon japonicus variety DUS test were clarified, the general principles for DUS determination of Ophiopogon japonicus were established, and the Ophiopogon japonicus DUS test guide was formulated.

Key words: Ophiopogon japonicus(L.f.)Ker-Gawl., new variety protection, distinctness,uniformity and stability(DUS), test guidelines
