    Potato virus Y (PVY) is one of the most important agent causing high losses in potato farms worldwide and is transmitted by many aphid species in a non-persistent manner. Several PVY strains occur and each is posing a different importance on numerous potato cultivars. In Belgium, the N strain group is reported as the most prevailing but no detailed information on the relative importance of the different PVY strains is available.
    Here we report on a survey performed in Belgian seed potatoes as harvested in 2010. We tested 2700 individual seeds from 54 seed potato lots coming from 54 farms in 24 administrative divisions in Belgium. The results revealed large differences in PVY incidence and strain differentiation, but there was no clear correlation between potato cultivars and PVY strain prevalence. Further characterization by multiplex PCR and partial sequence of the NIa gene confirmed that the NTN strain with 75% prevalence is dominant in Belgian seed potato farms, while the O strain was found only in a few locations. Finally, we could confirm the presence of both variants A and B of the necrotic NTN strain in Belgian seed potatoes. Additionally, for the first time the presence of the Wilga strain was confirmed.
