In order to raise the application value of dwarfing-sterile wheat in breeding,9 hybrid combinations of dwarfing-sterile wheat were selected,incorporating the technique of induction haploid by wheat×maize hybridization.1 fertile plants and 80 flowers were treated in each combination.The result showed that the average frequency of embryo formation was 12.4%,frequency of doubling was 50.8%.32 double-haploid wheat plants were obtained.
