France Received 1 March 1989 accepted 9 October 1989 Summary-The polymorphism of 9 enzyme systems ACP EC . AMY EC . GOT EC . IDH EC . LAP EC MDH EC . PGM EC . SDH EC TO EC . was studied in 198 wild cherry plus-trees selected mostly in France. The variability at 8. loci allowed the positive characterization of most of them 72 . Among the 45 plus-tree clones supplied to French nurseries in 1988 2 pairs remain indistinguishable. Keys for distinguishing wild cherries from sour or duke cherries were found in 3 enzyme systems ACP LAP SDH 3-10 additional bands were found in 33 sour or duke cherry cultivars of various origins compared to 286 wild cherries. But these isozymes are probably insufficient to allow detection of minor introgressions of sour cherry in wild cherries.
