Abstract
A single locus, 3-allele model is proposed for the phosphoglucoisomerase {PGI) allozymes observed in the California diploid species Fragaria vesca L. They have been designated Pgi-2b, Pgi-2c, and Pgi-2d. The results of mating system studies at two locations suggest that California F. vesca is predominantly a setting species in the populations examined. Evidence of three additional alleles in other Fragaria diploid species is also presented for this enzyme locus.
