Abstract: Xushu18 is a new sweetpotato cultivar with high resistance to root rot disease, high and stable yield, and broad adaptiveness. It was bred by Xuzhou Agricultural Science Research Institute. 52 excellent cultivars were bred from Xushu18 as a direct parent. The germplasm Xushu18 possessed rich genetic base, high disease resistance and high combining ability. Breeders should attach great importance on Xushu18 to improve sweetpotato breeding in the future. Meanwhile, wild species and foreign germplasm materials are also needed for broadening the genetic base of sweetpotato germplasm in China.

Key words: sweetpotato[Ipomoea batatas(L.) Lam.], Xushu18, germplasm resource
