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.
