Abstract:

In order to provide basis for purple sweet potato breeding, the grey multidimensional relation analysis was used to analyze and evaluate 9 agronomic traits of 14 purple sweet potato varieties. The results showed that the order of excellence in tested varieties was as below: Funingzi No.3, Longzi No.4, Fushu404, Rongshu910, Quanshu22, Quanshu32, Rongshu32, Quanshu9-6, Fushu006, Longzi No.5, Rongshu52, Puzishu No.5, Xuzishu No.2 and Longzi No.7. The result of the weighted incidence degree was anastomotic with the varieties performance.

Key words: Grey multidimensional relation analysis, Purple sweet potato, Evaluation of variety
