【摘要】 以国际植物新品种保护联盟(UPOV)制定的植物新品种DUS(distinctness, uniformity and stability)测试指南总则(TG/1/3)、箭筈豌豆DUS测试指南(TG/32/7)等技术文件为指导,对箭筈豌豆DUS测试指南的核心技术内容:测试性状和参照品种等开展了研究。在国内外共收集到51个箭筈豌豆品种,并进行连续2年的田间观测。观测性状总计31个,包括UPOV箭筈豌豆DUS测试指南中的23个性状,以及本实验发现有特异性的8个新增性状。对每个测试性状的表达状态、观测时期、测定方法、观测数量等进行了分级和详尽描述。共筛选出32个参照品种(国际21个,我国11个),确定了123个表达状态。并对UPOV箭筈豌豆DUS测试指南中"外种皮底色"和"种子形状"表达状态的分级进行了补充。本研究结果可为我国箭筈豌豆新品种DUS测试指南的制定奠定技术基础,对促进我国箭筈豌豆品种保护、审定和育种工作具有重要的意义。更多还原

【Abstract】 We used the general introduction to the examination of distinctness, uniformity, and stability(TG/1/3), guidelines to identify and conduct tests for distinctness, uniformity, and stability of common vetch(TG/32/7), and related documents developed by the International Union for the Protection of New Varieties of Plants(UPOV) as guidelines to study the core technical content of the common vetch DUS test guidelines, which include test characteristics and reference varieties. We collected 51 common vetch varieties from around the world and evaluated their characteristics in a 2-year field trial. We evaluated 31 test characteristics, including 23 UPOV common vetch DUS test characteristics, and eight new characteristics representative of the distinctness feature. The expression status, and the observation period/method/number of each characteristic were scientifically graded and accurately described. Finally, a total of 32 reference varieties(21 international varieties and 11 varieties from China) corresponding to 123 expression states were screened. We further complemented the expression states of "ground color of test" and "seed shape" in the UPOV common vetch DUS test guidelines. This study lays a technical foundation for the development of new common vetch varieties in accordance with DUS test guidelines in China. The establishment of these reference varieties and testing guidelines will be useful for the protection, validation, and breeding of common vetch in China.更多还原
