The 500 monoconidial isolates of Alternaria mali occurring in different locations, Suweon, Cheongju, Kochang, Daegu and Jinju, Korea, in 1983 were used to examine geographic variation of esterase isozymes. The electrophoretic patterns of esterases were qualitatively and quantitatively different between isolates. The 14 different bands were detected on the basis of the decreasing electrophoretical mobility, although all bands were not present in any of the isolates. A comparison of the frequency of esterase isozymes at different bands showed marked variations among the geographic locations. The geographic distance between A. mali populations did not correlate strongly with divergence in esterase isozymes, whereas A. mali populations within a geographic feature were more closely related than populations separated by a mountain range
