| 摘 要： | Sumai 3, a wheat variety resistant to Fusarium head blight(FHB), was crossed with Neimai 9, a commercial wheat cultivar with the resistance to powdery mildew.The SCAR(sequence characterized amplified region) markers of powdery mildew resistance gene Pm21 and four SSR(simple sequence repeats)markers flanking the major FHB resistance QTL(Qfhs.ndsu-3BS) in Sumai 3 were used to detect the resistance loci by marker assisted selection(MAS) in the plants of the F2 population.Identification of resistance to both powdery mildew and FHB in field showed that 12 plants resistant to both diseases were obtained.In addition, the agronomic traits of these plants were better than those of Sumai 3, and are perhaps the excellent parental materials for wheat breeding. |
