Turnip mosaic virus (TuMV), Cauliflower mosaic virus (CaMV) and Beet western yellow virus (BWYV) are considered as the most important viruses of canola, worldwide. In order to determine the distribution of these viruses in Golestan province, samples from three important canola growing areas of the province were collected during 2008 and 2009. The randomly collected samples were tested for the presence of TuMV, CaMV and BWYV through DAS-ELISA. The results revealed that canola field infection levels in 2008 with TuMV, CaMV and BWYV were at 4.5%, 2.5% and 6%, respectively. Canola field infection in 2009 with TuMV, CaMV and BWYV was at the levels of 8.33%, 1.66% and 6.33%, respectively. Data analysis showed that virus factor was significant for 2008 whereas region was the factor significant for year 2009. Furthermore, BWYV infection was confirmed through RT-PCR. It is to be mentioned that this is the first report of TuMV, CaMV and BWYV on canola in Golestan province.
