ABSTRACT
<p><b>OBJECTIVE</b>Botanical characters of germplasm resources of Chrysanthemum morifolium for medicine were observed and compared, which could offer reference for its genetic improvement and germplasm resources protection.</p><p><b>METHOD</b>Based on the random blocks field experiments design, twenty-six morphological traits were observed. The morphological differences among germplasm resources were compared by principal component analysis and cluster analysis.</p><p><b>RESULT</b>The coefficient of variation values for 17 of 26 traits indicated a high level of variation (above 20%). Six principal components which accounted for 77.14% of total variance were extracted from the principal component analysis. The 29 germplasm resources could be divided into two clusters.</p><p><b>CONCLUSION</b>There were large morphological variation among germplasm resources on Ch. morifolium for medicine.</p>
