At least three different origins of perpetual flowering habit have been reported in garden strawberry including 1) old European cultivars originating from Gloede’s seedling in 1866, 2) ´Pan American’, a putative mutant of ‘Bismarck’ selected in New Your by S. Cooper in 1898, and 3) introgression from F. virginiana ssp. glauca accession collected from Wassatch mountains in Utah . The genetic basis of the two oldest origins are unknown, but several studies have focused on the genetic control of perpetual flowering in modern cultivars that include the Wassatch source in their pedigrees.
