No cultivar name of record
This patent does not name the plant, and for its era that is ordinary rather than an omission. Before about 1980, breeders frequently patented a plant without giving it a cultivar name at all — the grant identified it by its number, its parentage and a written description of the flower and foliage. Most plant patents from the 1930s to the 1970s have no name in them.
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.
Abstract
A novel pear variety originating as a sport of Regal Red Comice, characterized by its solid red fruit color, Comice shape and smaller tree habit.
Show the legal claimThe single numbered claim as granted — the legal text that defines what this patent covers.
What is claimed is: 1. A new and distinct variety of pear tree, substantially as shown and described herein, distinguished principally from its parent, the Regal Red Comice, by being a spur-type tree bearing fruit, having a substantially solid red color throughout the growing season, with little or no purplish tint and having very slight yellowish undercoat when ripe, having substantially thicker and tougher skin, and having a rounded shape more nearly similar to the standard Doyenne Du Comice.
