| Abstract: | Developing new germplasm on head smut of maize and testing the correlative markers were studied using Longzao population that created by Maize Research Institute of Heilongjiang Academy of Agricultural Sciences.The result showed that 15 materials high resistance on head smut germplasm were created through the recurrent selection by S1 and half-sib selection,and 6 new inbred lines were created by complex cross,and their characters were high resistance on head smut,high combining ability,good quality.In the same time 3 new molecular markers were created,in order to test the high resistance on head smut germplasm. |
