摘　　要：采用人工接种和田间自然诱发相结合的方法， 对１ １００ 多份甘薯品种（系） 资源分别在苗期和成株期进行抗薯瘟病、蔓割病、疮痂病、根结线虫病等抗性测定。试验表明， 属于多抗的品种有华北４８、豆沙薯、甘薯３３０、湘农黄皮、湘薯６ 号、丰薯２ 号、潮薯１ 号、广薯１５、广薯１６、１７６、１７１４、 Ｒ１７ 等。农艺性状兼优的可直接利用的品种 （系） 有华北４８、豆沙薯、甘薯３３０、湘农黄皮、湘薯６ 号、潮薯１ 号、广薯１５、广薯１６、１７１４、 Ｒ１７ 等。这些品种分别在甘薯病区大面积示范推广应用。据１９８０～１９９８ 年不完全统计， 累计种植面积８０ 万ｈｍ ２， 增产粮食８ 亿ｋｇ。The resistance to Ralstonia solanacearum, Fusarium oxysporum ,Sphaceloma batatas and Meloidogyne incognita of more than 1100 various varieties (strain) of sweet potatoes was detected by artificial inculation and field natural induction in seedling period and vegetative period respectively from 1980 to 1998 The results showed that, Huabei 48,Doushashu,Ganshu 330,Xiangnonghuangpi,Xiangshu 6,Fengshu 2,Chaoshu 1,Guangshu 15,Guangshu 16,176,1714,R17 etc,were highly resistant,Huabei 48,Doushashu,Ganshu 330,Xiangnonghuangpi,Xianshu 6,Chaoshu 1,Guangshu 15,Guangshu 16,1714,R17 etc had excellent agronomical character and could be applied directly These varieties (strain) were demonstrated, popularized and applied in the large epidemic area of sweet potatoes respectively According to incomplete statistics, accumlative tested areas was 800 thousands hm 2 and increased potato yield about eight hundred million kg from 1980 to 1998
