ABSTRACT: 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.
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.
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.
There were large morphological variation among germplasm resources on Ch. morifolium for medicine.
