The Numerical Classification of Chrysanthemum Flower Color Phenotype

Abstract

In order to accurately define the different flower color phenotype of chrysanthemum,colorimeter was used to measure the various flower colors of 811 chrysanthemum cultivars.And the different methods of color classification(Q cluster analysis and ISCC-NBS color name chart)were compared.It was found that the results obtained from statistical methods couldn't fully describe the characteristics of plant color,while the definition of plant color from the color point of view was more accurate.According to the standard,all cultivars were divided into nine groups and the distribution range of flower color parameters of each color group was summed up.On this basis,the distribution analysis of the phenotypic color of chrysanthemum cultivars was completed.
