木瓜属植物新品种特异性、一致性和稳定性(DUS)测试指南的研制
Development of a Guideline for the Conduct of Tests for Distinctness,Uniformity and Stability of Chaenomeles New Varieties
摘要
Abstract
The characteristics variation pattern, stability and their relevance of varieties in the genus Chaenomeles were analyzed based on UPOV and China's assessment system. The selection principles of example varieties and testing characteristics were discussed. Twelve example' varieties and thirty-one testing characteristics (10 qualitative, 6 quantitative, and of pseudo-qualitative) were adopted for DUS test. For each characteristic a code was given to express the state. Twenty-four characteristics were of asterisked, such as plant type, flower color, flower diameter, polyphyll state, fruit shape, and peel crimpled state, and seven ones were of non-asterisked. The assessment standard for Distinctness, Uniformity, and Stability was put forward.关键词
