No cultivar name of record
This patent does not name the plant. Through the 1980s and early 1990s that was still common: naming every new cultivar only became standard practice as plants began to be marketed under brand names. 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.
Abstract
A new and distinct cultivar of apple tree which is distinctly characterized by its high fruit quality and its resistance to Venturia inaequalis (Cke.) Wint., the causal agent of the apple scab disease. This new variety of apple tree, now designated as COOP 22, is a seedling of known parentage planted in 1965 in the PW Breeding Orchard of the Department of Horticulture at the Illinois Agricultural Experiment Station, Urbana, Ill., which site is a cultivated area. In the above mentioned orchard, its position was Row 40, Tree 116, having the designation PRI 2016-100 in the breeding records. After observation the selection was asexually reproduced by grafting on seedling apple roots. The grafted material has maintained the described characteristics after propagation.
