Abstract
The subject apple variety comprises a new Red Delicious sport mutation (Ace strain) originating as a limb sport on a spur variety Red Delicious apple tree. The new variety is also of the spur type. It is unique in the following characteristics: Its leaves are significantly larger than the leaves of the parent tree and other spur Red Delicious apple tree varieties; its fruit possesses superior color characteristics and a very high degree of color consistency; its fruit is significantly larger than the fruit of the Bisbee strain Red Delicious apple tree; and the flesh and under layer of the epidermis of its fruit lose their green chlorophyll coloration in high degree at an early date. Accordingly, the fruit is characterized by an unusually white flesh color.
Show the legal claimThe single numbered claim as granted — the legal text that defines what this patent covers.
Having thus described my new and distinct variety of apple tree, I claim: 1. The new and distinct spur variety of Red Delicious apple tree characterized particularly, as contrasted with other spur varieties of Red Delicious apple trees, by the relatively large size of its interior spur leaves indicative of superior vigor and ability to support large, high quality fruit over long periods of time; by the early development of the red color of its fruit; by the uniformity of the red color on the front and back sides of its fruit; by the large size and deep red but bright color of its fruit; by the high color factor consistency of its fruit; and by the loss of chlorophyll in the flesh and underlayer of the epidermis of its fruit at an early date, substantially as shown and described.
