Starch gel electrophoresis was employed to distinguish the University of California-released strawberry cultivars. Isozyme patterns of 3 enzyme systems (PGI, LAP, and PGM) were studied. Fourteen of the 22 cultivars studied were classified uniquely by using the 3 enzyme systems. The use of electrophoresis as a tool in breeding clonally propagated crops is discussed.
