The morphological markers of Different phenotypes Echinacea purpurea.

Analysis germplasm resources genetic diversity of different phenotypes Echinacea purpurea. The phenotypic trait data of different morphology samples were measured and the correlation coefficient calculation and cluster analysis were conducted. Different samples differed in many quantitative traits and fake quality traits; there were certain correlation between some morphological characters; samples growth in the same habitat clustered into a major category. Results provide a theoretical basis for preliminary judgment of germplasm field screening; growth environment may have a greater impact on the external form of Echinacea.
