Abstract: 

Potato leafroll, the disease caused by potato leafroll virus (PLRV), is one of most important diseases of potato. Yield of infected plants may be reduced by as much as 90 %. Since the disease is important at potato seed production program and its symptoms (such as inward curling of the upper and lower leaves) were observed in Khorasan, the virus was detected by DAS-ELISA test and its distribution was determined during the course of the investgation. To determine the distribution of the virus in khorasan, from 86 fields of Bojnoord, Chenaran, Torbat jaam, Fariman, Torbat-e-Heidarieh (Jolgeh Rokh) and Torogh (Khorasan Agricultural and Natural Resources Researche Center), 2298 plants were randomly samples and DAS-ELISA test was used for detection 8.1, 16, 5.2, 8.6, 6.1 and 5.5 respectively. Also the geographical distribution of Myzus persicae (the vector of the virus) was surveyed. According the result of the survey, the population of the aphid is very low. Also, according the survey it seems that the aphid has very low role in the virus transmission and the most important manner of PLRV transmission in Khorasan is potato tubers.
