| Abstract: | Natural infections of sugar beet with Beet necrotic yellow vein virus (BNYVV), the causal agent of rhizomania, have been detected for the first time in Sweden in two small areas, one on the island of Öland and one in the Southeastern part of Scania. Single strand conformation polymorphism analyses of PCR products revealed that the infections on Öland were produced by A type BNYVV, whereas those in Scania were caused by the B type. This suggests that BNYVV has been introduced into Sweden at least twice. Alternatively, the virus may have invaded sugar beet from unknown native hosts. BNYVV RNA 5 was not detected in the samples investigated. |
