Grey Correlation Degree Analysis of 29 Varieties of Dahlia pinnate Cav.
摘要
Abstract
[Objective] To rapidly select excellent Dahlia pinnate Cav.varieties, and to establish a comprehensive evaluation system for the screening of D.pinnate.[Method] With 29 varieties of D.pinnate as experimental materials, we selected 11 quantitative traits as evaluation factors, and established an evaluation system based on the grey correlation analysis method to comprehensively evaluate the advantages and disadvantages of D.pinnate varieties.[Result] Two varieties of Yingyin-535 and Zitiaowen were screened, which had more full-bodied, brightly colored, and good comprehensive characters.Equivalence correlations of the two varieties were 0.847 4, 0.844 9, and their weighted relational grade of the two varieties were 0.864 9 and 0.854 8, respectively.[Conclusion]The grey correlation analysis method provided a theoretical basis for the selection and breeding of new varieties of D.pinnate.关键词
