Abstract: The tree of this disclosure is a newly discovered and stability tested color sport of the parent variety `Cortland`, which I have named `NS-911`. The new tree is distinguished by having more highly colored fruit than that of `Cortland` and `Redcort`, a color sport from the same source, and as having less conspicuous stripes within and masked by a solid blush which covers substantially the entire surface of the fruit. The ground color of fruit skin of each variety is substantially the same, but differs in terms of degree of coverage, with ground color patches being essentially absent from the surface of the fruit of `NS-911`. The new tree is distinguished from `Lamont` in having standard bearing and tree habit.
Claim: I claim:

1. A new and distinct Apple Tree substantially as herein shown and described, characterized particularly as to novelty by more extensive and more uniform red blush covering substantiallyall of the exterior of the fruit with only an occasional patch of ground color.
Description: BACKGROUND OF THE INVENTION

The variety `Cortland` is an old variety, introduced in 1915, by S. A. Beach, N.Y. State Agricultural Experiment Station, which has been unusually popular in the market place. Because the fruit of the variety has exceptional attractiveness,pleasing taste and notable keeping qualities, it has been well accepted in the consumer market. Trees of the variety `Cortland` are of exceptional hardiness and productivity; and, have been a popular variety in many old orchards throughout apple growingregions. Due to the premium market slot of the fruit of this tree, `Cortland` has been widely planted and occupies a substantial area of apple tree production acreage in the apple producing areas of the United States, Canada and elsewhere. With largepopulations of trees planted to satisfy market demand for this exceptional fruit, as with many other popular varieties such as `Red Delicious` and `MacIntosh`, numerous sports of `Cortland` have been discovered over the years. These have been isolatedand introduced, to a point where such related and improved trees share, and in some cases dominate, the market demand filled by the original `Cortland` variety, and more successfully compete with fruit of other varieties in the marketplace. Theoverwhelming popularity of `Cortland`, and sports of this tree, has led to the development of its own market class, which over the years has been expanded to contain a number of related but competing trees. Introduction of improved sports has generallyimproved the quality of fruit available to the consumer as `Cortland` in the market place.

The tree `NS-911` is such an improvement. This tree was discovered by me as a limb sport on an old specimen of `Cortland` growing in orchards under my control nearKentville, Nova Scotia, Canada. More specifically, it was initially noted becauseit produced a highly colored apple with a conspicuously more extensive and uniform red blush as compared to the fruit of adjacent `Cortland` trees. The fruit of this sport is essentially totally red and uniform to an extent that the stripes whichcharacterize the fruit skin color of most color sports of `Cortland` all but disappear, by being masked by a heavy red blush, in the color expression of the fruit of this tree. Further, it was clear that the extent of the blush and the general lack ofground color on the fruit surface made the fruit of this tree most unusual. Because of the well established and recognized consumer preference for apples of solid red coloration, I immediately saw the distinction of this sport from trees of `Cortland`near it; recognized the potential enhanced marketability of the fruit; and, I have observed in testing the fruit of the tree, that the tree also has retained the notorious high fruit flesh quality, flavor and keeping qualities of the parent `Cortland`variety.

I have caused the tree to be reproduced asexually by budding, and find that it is in fact one which holds its characteristics through successive generations and produces apples of a decidedly attractive form, color, and taste.

In taste, fruit interior quality, texture, shape and keeping qualities, the apples of my tree `NS-911` are not substantially different from those of `Cortland` and known color sports thereof, such as `Redcort`. However, the fruit of `NS-911` hasa more extensive and a more uniform red blush covering substantially all of the exterior of the apple. Only an occasional spot or patch of ground color occurs where fruit developed with its surfaces against a branch or was otherwise unusually shaded. This is in contrast to the fruit of`Redcort` which expresses a red blush over distinctive stripes which are even more prominently visible over more extensive patches of green ground color. The blush and underlying stripes of `Redcort` normally coveronly about three quarters of the surface of the fruit.

The tree `NS-911` is similar in habit to the parent `Cortland`. It forms a standard tree size and is standard in bearing habit. Tree branching habit and canopy density are substantially identical to that of the parent tree; and has a similarspreading habit and scaffold branch placement. Mature bark colors of the oldest branch of the original sport is tan and bears a heavy pattern of large lenticels of cork-like texture and color, which are elongated in shape and in a generally horizontalpattern in attitude. Mature bark of the parent tree is shaggy and gray. Leaf characteristics of my new tree are substantially identical to those of the parent variety.

BRIEF DESCRIPTION OF THE VIEWS OF THE DRAWING

FIG. 1 depicts the original sport of the new variety `NS-911` growing on the original parent `Cortland` tree. The sport is readily discernible by the distinctly different bark color and texture. This drawing depicts the habit, canopy and leafcoloration which is substantially the same as that of the parent tree. The depicted specimen is shown with fruit at a stage approaching harvest stage and shows the bearing habit of the tree.

FIG. 2, shows five whole fruit of the new variety from the stem end. Note that stripes are only faintly visible through a very uniform, heavy attractive red blush. Fruit stems and the russetting within the stem basin are also depicted andsimilar to those of the parent `Cortland`.

FIG. 3 illustrates, on the left, four specimens of fruit of the comparison variety `Redcort`; and, on the right four specimens of `NS-911` are shown. Specimens of each variety are positioned to show the blossom end, side view, and stem ends ofwhole specimens of fruit of the comparison variety and the new variety. The substantailly identical shape and size of the fruit of both varieties are depicted. This comparison also shows that the stripes of `Redcort` are more conspicuous than those of`NS-911`, and that `Redcort` has a much higher degree of ground color exposed beneath the blush. In contrast the surface of `NS-911` is more completely and more uniformly covered by a red blush which essentially masks the pattern of dark stripes.

The color descriptions presented in the botanical specifications to follow were taken from the color dictionary Munsell Book of Color except where general color values of ordinary dictionary significance are used.
