- Abstract:
- Twenty cultivars of Freesia hybrida were used to measure the characteristics of flower color.Royal Horticultural Society Color Chart (RHSCC) was firstly selected to describe the color and the colorimeter was used to measure the phenotypic value of flower colors.In order to provide the preliminary phenotypic quantitative basis for the genetic relationship judgment of the unknown variety of Freesia hybrida,and provide the scientific background for the definition of flower color in Freesia hybrida cultivar classification.The results showed that based on the results of RHSCC and the colorimeter,20 cultivars of Freesia hybrida were classified into four categories,including white,yellow,red,and purple.The results of the cluster analysis possessing the preferable corresponding to the RHSCC,which further confirmed the above classification.Meanwhile,the feature of CIELab system parameters in 20 freesias were analyzed and the distribution range of flower-color parameters in each distinct group was defined,which will set the basic foundation for the phenotype study of flower color in Freesia hybrida.
