SUMMARY: ‘Honeycrisp’ is one of the top-selling apple cultivars in the U.S., in high demand for its signature crunch and flavor. Despite its economic importance, Honeycrisp’s ancestry has previously been unknown due to incorrect breeding records. Researchers used new genetic techniques and DNA marker array technology to identify the extended pedigree of Honeycrisp, which includes the well-known cultivars Golden Delicious, Duchess of Oldenburg, and Northern Spy. This new pedigree information will be useful in future research studies to better understand Honeycrisp and its relatives and offspring. The study was led by recent University of Minnesota graduate Nick Howard, with support from RosBREED.
