植物品种DUS(Distinctness,Uniformity and Stability)测试是植物新品种审定、登记的必要环节。DUS测试指南是品种审定机构开展DUS测试的基本依据。本研究按照国际植物新品种保护联盟(UPOV)技术文件《TGP/7植物新品种测试指南的研制》规定的程序要求,以90份红豆草(Onobrychis viciifolia)品种资源为试验材料,在新疆乌鲁木齐开展了两年的田间试验,经过多次同行专家论证修订,完成了红豆草DUS测试指南报批稿。指南规定了红豆草DUS测试的31个测试性状及其观测方法和判定标准,13个标准品种,并详细介绍了红豆草DUS测试指南研制的过程及指南的主要内容。指南的制订为国内红豆草新品种特异性、一致性和稳定性的判定提供了技术依据,对加强我国红豆草新品种保护具有重要意义,为红豆草产业健康发展提供技术保障。
Development of distinctness, uniformity, and stability test guidelines for sainfoin
The DUS (Distinctness, Uniformity, and Stability) test is a necessary step in the approval and registration of new plant varieties. The DUS test guide articulates the procedure by which the variety certification authority carries out DUS testing. In accordance with the procedure requirements specified in the TGP/7 technical document of the International Union for the Protection of New Plant Varieties, we conducted a 2-year field test in Urumqi, Xinjiang, with 90 sainfoin variety resources as the test materials, and completed a DUS test guide draft for approval after several peer experts' performed field testing and revision. The guideline stipulates 31 test characteristics, observation methods, and criteria for a DUS test of sainfoin, and 13 standard varieties. The author introduced in depth the development process and main contents of the DUS testing guide of sainfoin. The formulation of these guidelines provides a technical basis for determining the specificity, consistency, and stability of new varieties in China and significantly strengthens the protection of new varieties of sainfoin in China. It provides technical support for the healthy development of the sainfoin industry.
