【Abstract】 In this paper, 87 sweetpotato varieties (lines) were used for innovating germplasm by hybridization. And 390 clones selected from the 13412 generations were identified for resistance to Bacterial Wilt. Resistance identification showed that there were 178 clones with resistance to Bacterial Wilt strainⅠ, 24 clones with resistance to Bacterial Wilt strainⅡ, and 37 clones with resistance to Bacterial Wilt strainⅠ&Ⅱ. The main characteristics of 46 varieties (lines) with resistance to Bacterial Wilt strainⅡ were investigated, as a result, 2 varieties (Quanshu148 and American No.7) showed superior characteristics with high yield, high starch content and good eating quality.更多还原
