百合花色表型数量分类研究

The Numerical Classification of Flower Color Phenotype in Lily

以筛选的257份代表性百合种质为试验材料,使用英国皇家园艺学会比色卡(RHSCC)和测色仪对花色表型进行测定,以测定数据为基础采用系统聚类对样本花色进行数量分类与分析,结合分类结果构建百合花色表型检索体系。结果显示:结合RHSCC和CIELab参数值将百合花色分为白、黄、粉、橙、橙红、玫红、红和暗红8大色系。各色系参数与CIELab表色空间的明度(L*)、红度(a*)和黄度(b*)有良好的对应关系,可实现对百合花色表型的定量描述。以花被片上下部颜色是否一致、量化分类所属色系、斑点类型与斑线有无作为第1、2、3级标准,将全部测定样本分为2组、8系、6型。本研究实现了百合花色表型的量化分类与分析,创建了百合花色表型分类检索体系,可为百合的分类与鉴定提供参考。

In this study,257 representative lily germplasms were selected as test materials.We used the Royal Horticultural Society Color Comparison Chart(RHSCC)and colorimeter to measure the flower color.Based on the measurement data,systematic clustering was used to classify the sample patterns quantitatively.Combining RHSCC and CIELab parameter values,the result showed that the lily flower colors could be divided into eight major color groups:white,yellow,pink,orange,orange-red,rose-red,red and dark-red.Each color group had correspondence with the lightness(L*),redness(a*)and yellowness(b*)of CIELab coordinate,which could realize the quantitative description of lily flower color phenotype.Based on the pure-pattern and multi-pattern,the numerical classification phenotype,the spots type and linear,all samples was divided into two groups,eight colors,and six types.This study had completed the numerical classification of flower color phenotype in lily and created a lily flower color classification index,meanwhile providing a reference for the classification and identification of lily varieties.
