Abstract: The aims are to study the genetic law of the main agronomic characters of Aconitum carmichaeli, and provide a basis for the breeding of Aconitum carmichaeli. The characters of parent roots and daughter roots of 14 Aconitum carmichaeli germplasm resources were analyzed. The correlation analysis, canonical correlation analysis and factor analysis were used to make multi-perspective research on the matrix composed of parent roots and daughter roots, the relationship among the characters was explored, and the importance of the characters in breeding was clarified. The results showed that there were different degrees of correlation among the characters of parent roots, the characters of daughter roots as well as between the characters of parent roots and daughter roots; there were six significant typical correlations between parent roots and daughter roots, and several representative indicators were selected from each group of variables to reveal the correlation between parent roots and daughter roots; the multiple variables in parent roots and daughter roots were reduced to five new factors through the factor analysis, which represented the intrinsic relationship between the variables in the system. In the process of characters selecting, those bulbs with long fibrous roots were the preferred choices; the choice of the number fibrous roots of bulbs could be relatively loosened; bulbs with stout main roots could make daughter roots have compact spacing; in addition to the cultivation of daughter roots, the cultivation of long main roots, thick fibrous roots and thick split-roots should also be taken into consideration, because these characters concerned the development of the next generation.
