Apple tree--Jonagored

Abstract

The subject apple tree variety comprises a new Jonagold apple tree (Jonagored) originating as a sport limb mutation of a Jonagold apple tree variety, Jonagold being a crossing of Golden Delicious with Jonathan, bred by New York State Agricultural Experiment station, Geneva, N.Y. The new variety of apple tree is generally similar to its parent with respect to trunk, branches, leaves, flowers and fruit but is uniquely characterized by the significantly large dark-red fruit with most of the apples having white lenticels, and its dark-brown trunk and branches. The new variety is further characterized by the keeping quality of its fruit.

Description

BACKGROUND AND GENERAL STATEMENT OF THE INVENTION

I discovered my variety of apple tree in my cultivated apple orchard located at Halen, Belgium. I noticed that the top of the Jonagold apple tree was bearing apples colored brown-red. This top and its fruit were unique on the parent tree, and the entire block of trees of Jonagold. Its fruit was already red in the beginning of September, while the rest of the cultivated fruit of Jonagold was still green.

Continued observation of the sport mutation over a period of three weeks indicated that the condition of the fruit remained stable although its color gradually became blood red.

I made cuttings from the sport in question and reproduced them by grafting. I have observed that these characteristics persist already through the second generation. The original sport of the top of my Jonagold apple tree and its descendants have the very same characteristics and fruit color as described above.

Claims

1. A new and distinct variety of fruiting apple tree Malus Mill-type, as described and illustrated, characterized by a vigorous, upright growth habit with large dark-red fruit and most with white lenticels, by the keeping quality of its fruit, the wood of the tree being darker than Jonagold, and the growth habit being the same as Jonagold.
