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, its resistance to infection caused by Venturia inaequalis (Cke.) Wint., the casual agent for the apple scab disease, due to the fact that this new cultivar carries the genetic factor Vf, and closely resembles 'Golden Delicious' but differs from 'Golden Delicious' in that it is resistant to apple scab, has freedom from stem cavity russet, bears a waxier skin, and green-tinged lenticels at harvest. This new variety of apple tree, now designated as COOP 16, was discovered by applicants in September, 1973, at Lafayette, Ind., in a cultivated area. The tree is a seedling of known parentage planted in 1966 in Block C of the Hinsley Breeding Orchard at the Horticultural Farm of the Purdue University Agricultural Experiment Station, West Lafayette, Ind. In the above orchard, its position was Row 21, Tree 79, having the description PRI 2174-3 in the breeding records. After observation, the selection was asexually propagated by grafting on seedling apple roots. The grafted material has maintained the described characteristics after propagation.
