Historical details

Frostbite was developed by the University of Minnesota in 1921, but not trademarked and released until 2008. For most of the intervening period it was relatively unknown outside of the university, where it was referred to simply as MN 447. However it has played a key role in the University of Minnesota's long-term apple breeding program, and contributed its excellent cold-hardiness to several other important varieties - it is a parent of Keepsake and Sweet Sixteen, and grandparent of Honeycrisp.
