Abstract: To select high quality germplasm resources of Clerodendranthus spicatus (Thunb) C.Y.WU, 15 germplasm resources ofC. spicatus (Thunb) C.Y.WU were evaluated by grey relational analysis and DTOPSIS. The result showed that the order of correlation grade valueri of each character in the overall evaluation ofC. spicatus (Thunb) C.Y.WU based on grey relational analysis was as follows: ursolic acid content >dry leaf weight/ stem weight ratio >rosmarinic acid content> stem height > stem diameter > plant dry weight. The result also showed that germplasm Cs8, Cs2, Cs15 were ranked as the top three, indicating that they had the best comprehensive traits, closest to the ideal germplasm, and these germplasm should be considered preferentially for further breeding. The grey relational analysis and DTOPSIS analysis gave a different overall evaluation result, and the biggest difference of the weighting correlation grade valueri’in grey relational analysis was only 23.27%, the difference was not obvious among germplasm. The biggest difference of Ci value in DTOPSIS using the weighting value ωk of grey relational analysis was 55.33%, the difference was obvious, the result of DTOPSIS should be considered preferentially.
