摘　　要：本指南遵循国际植物新品种保护联盟及我国对植物新品种特异性、一致性和稳定性测试指南制定标准的相关规定,以国内外164份紫云英种质资源为材料,进行多年多点种植试验,最终确定了33个测试性状,包括生长习性、开花期等30个必测性状和越冬性等3个选测性状作为紫云英DUS测试性状;同时规定了测试性状的分级代码和判定标准;筛选了23个品种作为测试指南的标准品种,最终形成了紫云英新品种的DUS测试指南。In accordance with the relevant regulations of the International Union for the Protection of New Variety of Plant and the guidelines for the testing of specificity,consistency and stability of new variety of plant in China,the planting experiment for years in many sites was conducted by using 164 Astragalus sinicus L.germplasm resources at home and abroad as materials,and finally 33 test traits were determined,including 30 required traits such as growth habit and flowering time and 3 selected traits such as overwintering ability,of which characters were used as DUS test characters of Astragalus sinicus L..At the same time,the grading code and criterion of test character were specified.23 varieties were selected as the standard varieties of the test guide,and finally the DUS test guide of the new varieties of Astragalus sinicus L.was formed.
