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.
