Ditto! I came across this site some time ago trying to find a place where I could buy a Frostbite (nee Minnesota 447) apple. My aunt has a tree and its apples make a hell of a cider. Turns out that he really likes this particular variety. [0]

I don't think it is rare for a university to have these kinds of breeding programs and put patents on the result. The one near me does that with cherries.
