摘　　要：为了研究在高纬度地区引进和利用CIMMYT玉米种质对丝黑穗病抗性的影响,采用田间人工接种方法测定了部分用CIMMYT种质Pob45和Pob46与黑龙江省骨干自交系杂交构建的半外来群体的选系对丝黑穗病的抗性。结果表明在这些含CIMMYT玉米种质的半外来群体的选系中,对丝黑穗病表现中抗及以上的占一半以上,其中高抗占35.9%。CIMMYT种质的引进总体上有利于提高黑龙江省种质资源对丝黑穗病的抗性。The resistances to maize head smut of some lines from semi-exotic populations containing CIMMYT germplasm and local lines were identified by the method of artificial inoculation under field condition to study the effect on resistances to head smut in introducing and using CIMMYT germplasm in high latitude area.The result suggested that in all lines selected from semi-exotic populations constructed by crossing CIMMYT germplasm Pob46 and Pob45 with main lines in Heilongjiang province,more than a half of them were middle or high resistant to head smut and the high resistant ones accounted for 35.9%.The introduction and utilization of CIMMYT maize germplasm in general would enhance resistance resources to head smut in Heilongjiang province.
