Comparisons of protein patterns obtained by two-dimensional polyacrylamide gel electrophoresis of 10 isolates of cereal cyst nematodes from nine locations in Sweden revealed greater differences between the two groups of Swedish Heterodera avenae, referred to as strict H. avenae and the Gotland strain of H. avenae, than were anticipated on the basis of pathogenicity tests and morphological data. Within each of these two major groups, each geographic isolate showed small and unique pattern differences. No pattern similarities or differences could be found to distinguish all members of any given pathotype from isolates of other pathotypes.
