摘　　要：小麦赤霉病是世界范围灾害性小麦病害。为了培育和推广抗赤霉病小麦品种,解决赤霉病对长江中下游地区小麦生产的危害。通过多年多点鉴定试验,使高产育种和抗赤霉病育种技术有机结合,运用"综合性状协调点"的观点,培育出了综合性状优良,表现既高产稳产又抗赤霉病(MR-R)小麦品种扬麦18,在生产上大面积推广应用。该品种的育成与推广应用初步实现了小麦抗赤霉病育种目标。Fusarium head blight （FHB） was a destructive disease of wheat in warm and humid wheat growing areas of the world, especially in China, and caused losses in grain yield and quality. Breeding for FHB resistance had been difficult, due to the multiple components of resistance, limited understanding of the genetic basis of the various forms of resistance, genotype and environment interaction, and the high cost of phenotype. For the contradiction between high resistance and high yield traits,and the complex of the inheritable mechanisms of resistance,it was still a worldwide hard nut to crack.In order to foster and promote the resistance variety to scab, and solved the question in the middle and lower reaches of the Yangtze River and increase the wheat production. In the paper, combining the high-yield breeding and the scab breeding route, and utilizing the view of ＂comprehensive co-ordination point trait＂, yangmai 18 had been breed and showed the fine comprehensive agriculture traits in the multi-year and multi-place, and performances both high and stable yield and resistance （MR-R） to wheat scab in the production of large-scale application. Incubation and development of the species realized initially the objectives of wheat breeding for scab resistance.
