摘　　要：小麦赤霉病严重威胁我国粮食和食品安全,培育抗赤霉病小麦品种是解决该病害最经济有效的途径。20世纪90年代后,以扬麦158为代表的扬麦、宁麦系列中抗赤霉病品种的育成和大面积推广有效抵御了长江中下游麦区的赤霉病危害,使我国抗赤霉病育种处于国际领先水平。尽管全球明确了7个抗赤霉病基因,为开展抗赤霉病育种提供了重要支撑,但由于赤霉病抗性机制复杂,实现高抗与高产的协调仍极其困难,抗赤霉病仍是当前及未来我国小麦育种的主要目标。对“十三五”期间我国小麦新品系和审定品种的抗性情况以及我国抗赤霉病育种方面取得的进展进行了综述,并提出了重视挖掘和利用扬麦等推广品种中优异抗性基因、将Fhb1导入扬麦等主栽品种的育种技术路线和重视表型精准鉴定等建议,以期为实现我国抗赤霉病育种突破提供借鉴。Fusarium head blight(FHB)is one of the most destructive wheat disease that threats to grain yield and food security in China.FHB resistant wheat varieties breeding is the most economical and effective way to manage the problem.Since 1990,the wheat cultivars of Yangmai and Ningmai series with moderate resistant to FHB played an important role in controlling the destruction of FHB in the Yangtze River area,resulting in our FHB resistance breeding reach to the international leading level.Although only seven resistance genes have been identified in wheat so far,which provide important support for the development of FHB resistant wheat variety,it is still very difficult to obtain wheat varieties with high level of resistance to FHB in combination with high yield due to the complex genetic mechanism.FHB resistant wheat variety breeding is still the main breeding objective in China at present and in the future.We summarized new FHB resistant lines/cultivars in China during“the 13th Fiveyear Plan”period,and suggested to identify the new FHB resistance genes/loci from Yangmai series wheat and introduce Fhb1 into Yangmai cultivars.In addition,it will be very important to pay attention to develop the high efficiency and accurate new technology for FHB phenotype.This review was expected to provide some comments for the breakthrough in FHB resistant wheat breeding in China.
