Isozyme patterns of Armillaria intersterility groups occurring in British Columbia

Abstract
Isozyme patterns for esterase and polyphenol oxidase were determined for diploid isolates of the six Armillaria intersterility groups collected in British Columbia. Factor analysis of digitized isozyme banding patterns separated A. bulbosa, A. ostoyae, and groups V and IX of Anderson and Ullrich. Results suggest that isozyme patterns may be used to identify subgroups within intersterility groups and to identify closely related intersterility groups.
