摘　　要：为扩大马铃薯育种遗传背景,丰富育种亲本,通过田间自然发病和人工接种鉴定两种方法,对103份从CIP引进的马铃薯资源进行晚疫病室内接种鉴定。结果表明:8份材料表现高抗,12份材料表现抗病。以2份抗病材料为亲本配制5个杂交组合,对788个F1单株进行晚疫病抗性鉴定,结果显示抗晚疫病植株数占总株数的59.65%,感晚疫病植株数占总株数的40.35%。本试验筛选出的抗性资源可以作为抗病育种的重要亲本加以利用。In order to expand the genetic background of potato breeding and enrich breeding parents,103 potato resources imported from CIP were inoculated and identified by natural disease and artificial inoculation.The results showed that 8 materials showed high resistance and 12 materials showed disease resistance.Five cross combinations were prepared with two resistant materials as parents,and the resistance of F1788 individuals to late blight was identified,the results showed that the number of plants resistant to late blight accounted for 59.65%and 40.35%of the total plants.The resistant resources screened in this experiment could be used as important parents in disease resistance breeding.
