Abstract

The invention provides a method for laodelphax striatellus to obtain a rice black-streaked dwarf virus (RBSDV) from refrigerated diseased leaves. The principle of the invention is as follows: storing plant leaves carrying RBSDV by using a refrigerated method, obtaining RBSDV for laodelphax striatellus from refrigerated diseased leaves by a feeding method, and obtaining laodelphax striatellus with RBSDV applied in inoculating and identification after laodelphax striatellus passes a circulative period of virus. The varietalresistance identification method established by the invention can overcome the technical bottleneck of difficult long-term storage of diseased plants by adopting the method of obtaining the virus which feeds laodelphax striatellus with diseased plant better, broadens the varietalresistance identification time, and is hopeful for quickening the screening speed of disease-resistant resources and breeding process of disease-resistant varieties.

Description

technical field

[0001] The invention relates to a method for obtaining rice black-streaked dwarf virus from frozen diseased leaves by brown planthopper and its application in agriculture, belonging to the field of agricultural science and technology. Background technique

[0002] Rice black-streaked dwarf virus (Rice black-streaked dwarf virus, RBSDV) is a viral disease transmitted by the striatellus striatellus. It infects rice and causes rice black-streaked dwarf disease. Once the rice is infected, it will not be harvested. Since the disease was discovered in Yuyao County, Zhejiang Province, my country in 1963, it has mainly occurred in indica rice-producing areas in southern Zhejiang in the last century, but it has rarely been found in major japonica rice-producing areas such as Jiangsu. In early 2004, rice stripe blight broke out in Jiangsu and other provinces, and a batch of disease-resistant varieties were rapidly popularized and applied on a large scale, which played ...
