摘要:水稻条纹叶枯病是以灰飞虱为介体传播的病毒病,给中国水稻生产造成了严重损失。利用品种自身的抗病性被认为是防治病害最有力的方法。本文从条纹叶枯病的病害特征、分子生物学研究进展、灰飞虱对条纹叶枯病的传毒特性和鉴定方法及条纹叶枯病抗性遗传的研究进展、抗条纹叶枯病育种研究进展几个方面进行综述,并对水稻抗性研究存在的相关问题和今后研究方向进行了探讨。

Abstract:Rice stripe virus (RSV) is transmitted by small brown planthopper, which has caused serious damage to rice production in China. Using resistance of varieties is considered to be the most effective method for disease control. It was summarized in this paper from the aspects of rice stripe disease characteristics, research progress on molecular biology, virus transmission characteristics and identification method of the small brown planthopper to rice stripe disease, advances in the genetics of resistance to rice stripe disease and rice stripe disease resistance breeding. At the same time, the existing problems in rice resistance researches were pointed out, and the solution was suggested.
Key words:Oryza sativa L;rice stripe disease;small brown planthopper;resistance;breeding
水稻(Oryza sativa L.)作为中国主要粮食作物之一,对保障国家口粮绝对安全发挥了重要作用[1]。水稻病虫害严重影响水稻产量,危害巨大,其中稻飞虱是水稻中危害最严重的害虫之一,不但自身可以通过刺吸取食为害水稻植株,而且可以作为传播介体传播病毒病[2]。
水稻条纹叶枯病病毒(Rice stipe virus,RSV)属纤细病毒属(Tenuivirus),以灰飞虱[Laodelphax striatellus Fallén (Homoptera: Delphacidae), small brown planthopper, SBPH]为介体传播,并且RSV可以通过灰飞虱经卵传播给后代[3]。该病害最早发现于日本长野县和群马等地[4],曾在日本、韩国和中国多次严重暴发。本文从条纹叶枯病的病害特征、分子生物学研究进展、灰飞虱对条纹叶枯病的传毒特性和鉴定方法、条纹叶枯病抗性遗传的研究进展、抗条纹叶枯病育种研究进展几个方面进行综述,并对水稻抗性研究方面存在的相关问题与今后研究方向进行展望。
