Abstract:

Ribosomal DNA (ITS rDNA) sequence data for two geographically separated isolates of Heterodera filipjevi from Russia were identical, and were 99.7% similar to rDNA sequence from Swedish East and West Gotland strains of H. avenae. These data are consistent with the view that the 'Gotland strain' of H. avenae and H. filipjevi are conspecific. The ITS rDNA sequence from an isolate of H. latipons from the Rostov region of Russia was 98.1% similar to the ITS rDNA sequence of an isolate from Gilat, Israel, the type locality of H. latipons, which suggests the possibility that the two morphologically similar, but geographically separated, isolates might be sibling species.
