| Abstract: |
| Objective Mensurate and analyze the quantitative traits of Bo and Qiaster tataricusgermplasm, providing reference for scientific evaluation and comprehensive utilization of aster tataricus germplasm. Methods Mensurate the twelve quantitative traits of aster tataricus, systematically analyse the quantitative traits of aster tataricus by using principal component and cluster analysis. Results There wereScoefficients variation values of quantitativetrait of the aster tataricus leaf and root above 50%, the former three principal components accounted for 85.48%, and the 122 germplasm resources could be divided into three cluster. Conclusions There were abundant germplasm exist in Bo and Qi aster tataricus, which could provide scientific basis for the variety selection of aster tataricus. |
