Construction of a comprehensive evaluation system for polychromatic cut chrysanthemums and screening of fine varieties
摘要
Abstract
[Objectives]The purpose of this study was to develop a comprehensive evaluation system for polychromatic cut chrysanthemums and to identify varieties with superior overall traits from diverse polychromatic resources.[Methods]Field experiments were conducted to observe the main traits of 58 polychromatic cut chrysanthemum varieties preserved in the Chinese chrysanthemum germplasm resource center.Evaluation indicators for selecting these varieties were determined through expert consultation and by referencing quality trait evaluation systems used for other ornamental plants.A comprehensive evaluation system was then developed to identify varieties with superior overall traits.[Results]Eight primary indicators were established to evaluate the traits of stems,leaves,and flowers,including plant height,stem diameter,leaf toughness,leaf shape index,angle of petiole,flower diameter,number of ray florets and vase life.Additionally,two innovative indicators:uniformity of the polychromatic pattern and distinctness of the polychromatic pattern,were incorporated.The weights of these indicators were calculated using the analytic hierarchy process,revealing that uniformity and distinctness of the polychromatic pattern had the most significant impact on the quality traits of polychromatic cut chrysanthemums,with weights of 0.277 and 0.176,respectively.The remaining indicators had relatively smaller effects.K-means clustering analysis of the weighted scores classified the 58 varieties into three categories:excellent,good,and poor,with cluster centers of 2.81,2.17 and 1.53,respectively.The experiment identified 19 superior varieties(32.76%),30 good varieties(51.72%),and 9 inferior varieties(15.52%).[Conclusions]This study developed a comprehensive evaluation system for polychromatic cut chrysanthemums,consisting of 10 key indicators.Among these,uniformity and distinctness of the polychromatic pattern were identified as the most influential.The system provides an effective method for evaluating and classifying polychromatic cut chrysanthemum varieties.From 58 evaluated resources,19 superior varieties were identified,offering high-quality parental material for future breeding of exceptional polychromatic cut chrysanthemums.关键词
