无花果新品种DUS测试指南的研制

Study on Test Guideline of Distinctness,Uniformity and Stability of Fig

植物新品种特异性(Distinctness)、一致性(Uniformity)和稳定性(Stability)简称为DUS测试指南,是进行植物新品种实质审查的基础,以国际植物新品种保护联盟(UPOV)的TG/1/3和TGP系列文件为重要指导,通过连续2个生长周期的田间试验,编制适合于我国无花果新品种测试的指南,详细阐述了无花果测试指南主要内容及研制过程,筛选了63个测试性状及性状对应的表达状态、确定了20个标准品种和DUS判定的标准,为无花果新品种测试与授权提供技术支持。

The distinctness,uniformity and stability（DUS）test guideline was the reference and technical standards for the substantive examination.According to the DUS test theory of TG/1/3and the test guidelines’ procedures of international union for the protection of new varieties of plants（UPOV）,two growing cycles of field trial were carried out to study on the DUS test guideline of fig.In this paper,the main aspect of test guideline were elaboratedin detail.Thus 63 characteristics,20standard varieties andtechniques for DUS assessment of fig were determined.The DUS test guidelines of fig will provide a standard technology to accelerate the development of plant variety protection.
