Abstract: A comparison experiment on 10 introduced sweet potato varieties were studied in some agronomic traits including characteristics and yield by using Jinshan57 as control in 2012. The results showed that, the dry matter yields per 667 m2 of Eshu6 and Xiangshu75-55 were 600.5 kg and 639.5 kg, and the starch yields of Eshu6 and Xiangshu75-55 were 392.0 kg and 431.3 kg, and were both higher than the control, these two varieties also showed excellent comprehensive characters, could be used as a high-starch varieties,further extended and demonstrated at Ningde.
