Variety of apple tree named Jonagored Supra
A new and distinctive variety of apple Malus domestica, tree named Jonagored Supra, a sport mutation of the apple variety Jonagored, uniquely characterized from its parent variety by the rounder form of its fruit; its slightly softer red-colored, approximately 90% solid blush having scarcely visible, very fine red stripes in it and approximately 10% of its surface is striped; by the earlier ripening and picking dates of its fruit; by the tree's distinctly weaker growth habit, the very dark brown to greyed-purple color of its wood; more pubescence and a lower amont of lenticels; and by the irregular margin of its leaves which is generally serrate but some are also biserrate and serrate-biserrate. Extended observation has further indicated that the Jonagored Supra is virus free, and is an improvement on the Jonagored variety with respect to its growth habit, color and productivity.

BACKGROUND OF THE INVENTIONThis invention relates to a new and distinct variety of apple tree named Jonagored Supra.
The new apple variety was discovered in a cultivated Jonagored apple orchard located at Halen, Belgium as a sport mutation of the Jonagored apple tree, U.S. Pat. Plant No. 5,937. It was noted that one tree in the orchard was unique and different in appearance from the entire block of Jonagored trees. This whole tree mutation was propagated by means of a probably spontaneous mutated eye that was taken as budwood. Its fruit coloring started with a green-orange-red color about 10th August, while the coloring of the cultivated fruit of Jonagored started later with a striped-brown-red color.
Observation of the mutated tree over a period of five weeks indicated that the condition of the fruit remained stable although its color gradually became dark-red with scarcely visible very fine red stripes in it. In comparision with the parent variety, the Jonagored Supra is already, picking-ripe and completely red, eight days before the fruit of the parent variety. Cuttings were made from the sport mutation and the new variety was reproduced by grafting. Extending observation in Halen, Belgium has shown that the unique and distinguishing characteristics of the mutated tree and its fruit have remained consistent through its third generation descendants. Both the descendants and the original mutated tree continue to share the very same characteristics and fruit color described. Extended observation has also indicated that the Jonagored Supra is virus free and it is an improvement of the Jonagored variety with respect to its growth habit, color and productivity.
Various differences between the parent Jonagored apple variety and the new Jonagored Supra apple variety are itemized in the following comparison table. With respect to the following dates of the Jonagored parent variety, the United States Plant Patent and the table of characteristics from the testing station in Brogdale, England was used.
