(2)(4)Department of Entomology, Purdue University, West Lafayette, IN 47907; (3)Department of Plant and Forest Protection, Swedish University of Agricultural Sciences, Alnarp. Phytopathology 79:927-933. Accepted for publication 1 May 1989. Copyright 1989 The American Phytopathological Society. DOI: 10.1094/Phyto-79-927.

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.
