By eight qualitative and nine quantitative traits investigated to assess its genetic variation of D. doryphora Hance in Taiwan. According to the distribution frequency, the qualitative traits of matured leaf color, young leaf color, stem color and bud color were in uniform. These traits are suitable for the assessment of genetic variation and species identification. The quantitative traits of medial leaf width, the ratio of leaf length and medial width could be used as important indicators for species identification. Based on plant traits, the cluster analysis showed the overlapping distribution in regions for D. doryphora Hance. In this paper, studies of D. doryphora Hance in Taiwan have been established, and such important information will be useful in germplasm collection, evaluation and application.
