We used microsatellite loci to investigate the parentage of the apple cultivar 'Honeycrisp', a patented University of Minnesota introduction. In an attempt to find the correct parents, we also examined other apple varieties associated with the University of Minnesota apple breeding program. Based on written records from the 1960s, the presumed parents of 'Honeycrisp' were 'Honeygold' and 'Macoun'. We were able to exclude both of these as parents, but found that 'Keepsake' was consistent as one of the parents. A second potential parent could not be discovered. 'Haralson', another commercially important cultivar from the University of Minnesota, is likely from a cross between 'Malinda' and 'Wealthy'.
