小麦抗赤霉病的遗传改良进展

Review on Improvement of Fusarium Head Blight Resistance in Wheat

小麦赤霉病是一种流行性的毁灭性病害,近年来在我国逐渐由长江中下游地区向黄淮麦区蔓延,给我国的小麦生产和粮食安全带来严重威胁。系统阐述了我国小麦抗赤霉病的遗传机制、外缘抗源的利用及抗赤霉病品种的选育等方面的遗传改良研究进展。分析了小麦抗赤霉病育种的2种技术路线,提出在加强小麦抗赤霉病优秀种质资源搜集的同时,结合分子育种技术与常规育种手段,加快小麦赤霉病抗性改良研究进程。

Fusarium head blight is a epidemic destructive disease, which has been gradually spread from the middle and lower reaches of Yan- gtze River to the Huang-Huai wheat area in recent years. It has posed a serious damage to the wheat production and food security of China. This research expounded systematically the research progresses in genetic mechanism, the utilization of peripheral antigens and the breeding of resistance to fusarium head blight. Then, the two strategies to improve fusarium head blight resistance were analyzed. Finally, it was proposed that we should strengthen the collection of excellent germplasm resources, combine molecular breeding techniques with conventional breeding methods, and accelerate the improvement research on resistance to fusarium head blight.
