摘要:
植物新品种特异性、一致性和稳定性(DUS)测试是新品种保护的基础和依据,测试性状的筛选是DUS测试的核心。为制定无髯鸢尾DUS测试指南,初步确定测试性状43个,结合性状间R型聚类分析性状间相关性,去除相关性大、贡献较小的雌蕊长、叶长性状,最终确定操作性强、区别明显的测试性状41个;利用品种间Q型聚类分析确定测试指南的分组性状4个;对性状进行分级及分布分析,保证无髯鸢尾测试指南的可行性,为无髯鸢尾品种测试与授权提供技术支持。

Abstract:
The test of distinctness, uniformity and stability (DUS) of new plant varieties was the foundation for new varieties protection. Traits Selection is key to DUS test. To establish beardless iris DUS testing, 43 traits were selected preliminarily. After removing length of leave and stigma with R-type cluster analysis, 41 traits with strong operability and distinct difference were finally determined; Four grouping traits were selected by Q-type cluster analysis; The classification and distribution of traits were analyzed to ensure the feasibility of the test guide, which improved the completion of DUS test guideline and based for test and authorization of varieties.
Key words:  Beardless Irises  DUS  Traits Selection
