用甘薯蔓割病菌和薯瘟 2个致病型菌对福薯 2号及我省主栽品种新种花、金山 57和湘薯 75-55分别进行田间接种鉴定 ;并在老瘟地上设置品种圃。结果表明 :福薯 2号表现高抗蔓割病 ,与高抗品种金山 57之间无显著性差异。对薯瘟病表现为高抗 型而感 型 ;但在 型菌系的老病地上其受害损失较轻 ,分别比湘薯 75-55和金山 57增产 9.1 %和 75.7%,显示出明显的耐病能力
Fusarium No. 2 and new species of flowers, Jinshan 57 and Xiangshen 75-55 of Fushu No.2 were identified by inoculating two pathogenic bacteria of sweetpotato and potato blast, respectively. In addition, . The results showed that: Fushu 2 showed high resistance to CTC, but no significant difference with that of Jinshan 57. It showed high resistance and resistance to the blast disease. However, it lost less damage in the germ-line stage, which increased 9.1% and 75.7% respectively than that of Xiang 75-55 and Jinshan 57, showing obvious disease-resistant ability
