摘要：

本文采用田间人工接种方法研究了部分含CIMMYT玉米种质的半外来群体选系对丝黑穗病的抗性。结果表明在用CIMMYT种质Pob45和Pob46与黑龙江省部分自交系杂交构建的半外来群体的选系中，对丝黑穗病中抗及其以上的选系占一半以上，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。

Abstract:

The resistances to maize head smut of some lines from maize semi-exotic populations containing CIMMYT germplasm and local lines were identified by the method of artificial inoculation under field condition. The result suggested that in all lines sellected from semi-exotic populations constructed by crossing CIMMYT germplasm Pob46 and Pob45 with lines in Heilongjiang province, more than a half of them were middle resistant to head smut and the high resistance accounted for 35.9%. The introduction and utilization of CIMMYT maize germplasm in general whould enhance resistance resources to head smut Heilongjiang province.
