水稻抗条纹叶枯病的遗传与育种研究进展

Progress of Genetic Research and Breeding on the Resistance to Rice Stripe Disease

水稻条纹叶枯病是由灰飞虱(LaodelphaxstriatellusFallen)传播的病毒性病害。近年来,在中国许多水稻种植地区再流行,并成为部分地区水稻生产中的第一大病害。该文对水稻抗条纹叶枯病近年来的流行情况、水稻品种抗性资源筛选、抗性基因的定位和育种利用等进行了综述,并对今后水稻抗条纹叶枯病的育种进行了展望。

Rice stripe disease is one of the most serious viral diseases in the temperate and regions of Japan, China and Korea. The disease is caused by rice stripe virus （RSV） and transmitted by the small brown plant-hopper, Laodelphax striatellus. Since 2000, rice stripe disease has reappeared in the middle and lower Yangtze River in China, and has been responsible for the greatest loss in rice production in this region. The progress in the current spread situation, screening of the resistant resources, mapping of the resistant genes and the breeding of the resistant varieties to RSV were summarized in this paper. Finally, the prospect on the breeding of highly and persistently resistant varieties to RSV were also discussed.
