Variety of apple tree named Excel
A new and distinctive variety of apple Malus domestica, tree named Excel, a sport mutation of the apple variety Jonagold, uniquely characterized from its parent variety by its much better color intensity over 50% or more of the surface of the fruit with a solid bright red colored blush with scarcely visible very fine red stripes in it and a smoother texture of the skin surface. Also the ground color of its fruit keeps longer green. The fruit has a higher acidity and a longer and thinner brown/red stalk, and has earlier ripening and picking dates. The tree is also characterized by distinctly dormant fruit buds on tips which have a conical shape and by its dark brown-red wood with clearly more pubescence and fewer but bigger lenticels than its parent variety.

BACKGROUND AND GENERAL STATEMENT OF THE INVENTIONThis invention relates to a new and distinct variety of apple tree named Excel.
The new apple variety was discovered in a cultivated Jonagold apple orchard located at Halen, Belgium as a sport mutation of the Jonagold apple tree. Jonagold being a crossing of Golden Delicious with Jonathan, bred by New York State Agricultural experiment station, Geneva, N.Y. It was noted that a branch of a Jonagold tree in the orchard was unique and different in appearance from the entire block of Jonagold trees, and was bearing brown red apples about the beginning of September while the rest of the Jonagold fruit in the orchard was still green.
Observation of the spontaneous mutated branch over a period of three weeks indicated that the condition of the fruit remained stable although its color gradually became beautiful bright red. In comparison with the parent variety, the Excel has a much better color intensity over approximately 50% or more of the surface of the fruit with a solid bright red colored blush with scarcely visible very fine red stripes in it. The sport is already colored and picking-ripe ten days earlier than the fruit of the parent variety.
Cuttings were made from the mutated branch and the new variety was reproduced by grafting. Extended observation in Halen, Belgium has shown that the unique and distinguishing characteristics of the mutated branch and its fruit have remained consistent through its third generation descendants. The original mutated branch and its descendants have the very same characteristics and fruit color as described in this patent. We can say that the Excel is virus free and it is an improvement of the Jonagold variety with respect to its growth habit, color and productivity.
Various differences between the parent Jonagold apple variety and the new Excel apple variety are itemized in the following comparison table.
