用甘薯瘟 2个致病型菌株对我国南方薯区 16份主栽品种分菌系接种鉴定 ,结果表明新种花、胜利百号等 10份表现为高感～感病。瑞薯 1号等 3份为高抗Ⅰ型菌、感Ⅱ型菌 ;徐薯 18则为中抗Ⅱ型菌、感Ⅰ型菌。广薯 88-70和湘薯 75 -5 5显示出高抗Ⅰ型菌兼具中抗Ⅱ型菌。用蔓割病菌对 16份主栽品种接种鉴定结果表明 ,广薯 111、潮薯 1号等 7份表现高感～中感 ;而福薯 2 6、岩薯 5号等 9份则为中抗～高抗
Two pathogenic strains of sweet potato blast were used to inoculate 16 main cultivars in southern China’s potato area. The results showed that 10 new varieties, such as new species of flowers and Shengli No. 100, showed high sensitivity and susceptibility. 3, such as sweet potato 1 high resistance to type I bacteria, susceptible type II bacteria; Xushu 18 is moderate resistance type II bacteria, susceptible type I bacteria. Guangshu 88-70 and Xiangshu 75-55 showed high resistance to type I bacteria with moderate anti-type Ⅱ bacteria. Inoculation results of 16 cultivars showed that there were high and middle sense in 7 of Guangshuang 111 and Tanshu 1, while 9 of Fushuhuan 6 and Ianshu 5 were medium resistant ~ High resistance
