    摘要:

    水稻黑条矮缩病(RBSDVD,rice black-streaked dwarf virus disease)是以灰飞虱为主要传毒介体,由水稻黑条矮缩 病毒(RBSDV,rice black-streaked dwarf virus)引起的一种水稻病毒性病害。介体灰飞虱一经染毒,终身带毒,但不能通过虫 卵传毒。近十几年水稻黑条矮缩病在中国南方稻区广为流行,造成了水稻的严重减产。目前主要通过使用农药来防治其传毒 介体灰飞虱,但由于灰飞虱种群数量大,导致其防治效果不佳,而且存在环境污染的忧患,故培育和利用抗水稻黑条矮缩病的 水稻品种是综合防治水稻黑条矮缩病的基础。本文对水稻黑条矮缩病的分布及危害、抗病种质资源、抗性鉴定方法、抗病基因 /QTL 的定位、抗病分子机理及育种进行综述,为开展水稻黑条矮缩病抗性遗传研究和品种选育提供参考。

    Abstract:

    Rice black-streaked dwarf virus disease (RBSDVD),which is caused by Rice black streaked dwarf virus(RBSDV) and mainly transmitted by small brown planthopper (Laodelphax striatellus Fallén), is a severe viral disease in rice. Once infected, the vector small brown planthopper carries the virus for life, but it cannot be transmitted through eggs. In recent ten years, RBSDVD has been widely prevalent in rice areas of southern China,which caused serious yield reduction of rice. At present, pesticides are mainly used to control the virus vector small brown planthopper. However, due to the large population of small brown planthopper, the control effect is not good, and there are concerns about environmental pollution. Therefore, the cultivation and utilization of rice varieties resistant to RBSDVD is the optimal strategy. Within this article, we review the distribution and hazards of RBSDV, exploration of resistance germplasm resources, resistance identification methods, mapping of genes/QTLs for resistance to RBSDVD, resistance-conferring mechanism and breeding. We expect to provide insights in genetic dissection of the RBSDV resistance genes and their optimal use in rice resistance breeding.
