摘　　要：目的:通过对药用菊花种质资源的植物学性状观测、统计和分析,以期为药用菊花的遗传改良和种质资源保护提供依据。方法:采用随机区组田间试验设计,对药用菊花的26个形态性状进行测定,结合主成分分析和聚类分析,对药用菊花种质资源的形态差异进行分析。结果:在调查的26个形态学性状中有17个性状变异系数大于20%,前6个主成分对变异的贡献率达77.14%,通过聚类分析将29份药用菊花种质资源分为2类。结论:药用菊花种质资源间存在较大的形态分化。Objective： 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.Method：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.Result：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.Conclusion：There were large morphological variation among germplasm resources on Ch.morifolium for medicine.
