摘　　要：为了明确宁夏马铃薯(Solanum tuberosum L.)主栽品种对晚疫病的抗性,采用田间自然发病和室内人工接种的方法对14个马铃薯主栽品种开展了抗病性研究。田间自然发病结果表明,中心24号、宁薯4号、云薯6号、虎头、内薯7号、新大平属于抗病性较强的品种。室内接种表明,新大平、晋薯7号、中心24号、云薯6号、虎头、宁薯4号等6个品种表现为抗病。The resistant ability of 14 main potato cuhivars to late blight in Ningxia were investigated using the method of na- ture occurrence in the field and artificial inoculation in the lab. Results in the field indicated that 6 cuhivars showed high resistance to potato late blight, including Zhongxin No.24, Ningshu No.4, Yunshu No.6, Hutou, Neishu No.7, and Xindap- ing. Results in the lab indicated that Xindaping, Jinshu No.7, Zhongxin No.24, Yunshu No.6, Hutou and Ningshu No.4 had resistance to late blight.
