No cultivar name of record
This patent does not name the plant, which is unusual for its date — by the mid-1990s nearly every plant patent carried a cultivar name. The grant identifies this one by its number and by a written description instead.
Nothing here is missing from our records: the patent itself states no name. Where one exists we show it, and we do not invent one.

It is distinguished by its resistance to peach tree short life/bacterial canker complex, Armillaria root rot, and to several species of root-knot nematodes.
