| Abstract: |
A new and distinct variety of MacIntosh apple tree, `Bull MacIntosh,` originating as a whole tree mutation of the Malus sylvestris variety of `Starling` (U.S. Plant Pat. No. 7,617). This new variety is unique from its parent and other MacIntosh cultivars because the fruit begins coloring 35 days earlier than the parent and 45 days earlier than other MacIntosh cultivars. The new variety ripens to a 100% red blush as opposed to its parent, which ripens to a red striped coloration. The `Bull MacIntosh` cultivar reaches maturity with the `Starling` cultivar and 10 to 15 days ahead of other MacIntosh clones. |
| Claim: |
We claim:
1. A new and distinct variety of apple tree, Malus sylvestris, substantially as herein shown and described, characterized particularly as to novelty by the unique combination of avigorous, upright, spreading, medium density, regular bearing tree, producing fruits that develop color 35 days before the parent and finish coloring as a 100% bright red blush with no striping at maturity which occurs at the same time as the parent. |
| Description: |
FIELD OF THE INVENTION
A new and distinct variety of MacIntosh apple tree originating as a whole tree mutation of the Malus sylvestris variety of `Starling` (U.S. Plant Pat. No. 7,167), hereinafter referred to as the `Bull MacIntosh`. This new sport is unique fromits parent because the fruit starts coloring 35 days earlier as a red blush over a faint red stripe. The color develops as a solid, bright red blush with no striping. The color finishes to a virtually 100% solid, bright red blush.
DESCRIPTION OF PRIOR ART
The new variety, `Bull MacIntosh`, differs from its parent and other MacIntosh varieties in the following characteristics: A. The new variety develops color 35 days earlier than its parent, `Starling` (U.S. Plant Pat. No. 7,167) and`Greenslade` (U.S. Plant Pat. No. 2,982). It develops color 45 days earlier than `Hartenmac NS 219` (U.S. Plant Pat. No. 10,770), `Pioneer Mac` (U.S. Plant Pat. No. 7,002). `Apple Tree` Chick (U.S. Plant Pat. No. 5,508), Mutation of SummerlandRed McIntosh apple tree (U.S. Plant Pat. No. 4,383) and `Raikes` (U.S. Plant Pat. No. 3,390). B. The fruit on the new variety matures with `Starling`, 10 days ahead of `Apple Tree` Chick, `Raikes`, Mutation of Summerland Red McIntosh apple tree,`Hartenmac NS 219`, and `Greenslade` and 15 days ahead of `Pioneer Mac`. C. The color finishes as a 100% solid, bright red blush with no striping.
SUMMARY OF THE INVENTION
This new and distinct variety of MacIntosh apple tree was discovered in 1997 as a whole tree mutation of `Starling`, in an orchard planted in 1984 on the Leslie and Linda Bull farm near Casnovia, Mich. The new variety was noticed because thefruit started coloring the first week in July, about 5 to 6 weeks ahead of all other `Starling` fruit in the orchard.
Observations during the next two seasons confirmed the early coloring and also that the fruit colored with a solid, bright red blush with no striping as opposed to `Starling`, which colors with a distinct stripe. The mature fruit of the newvariety finishes to a 100% solid, intense bright red color with no striping.
In August of 1997, buds were taken from the original tree and trees for further testing were asexually produced into 200 trees. This new cultivar has been reproduced on Malling 9-337 and Malling 9 NIC 29 rootstocks and remains true to thedescription herein contained. The new variety had not been grown on its own root.
BRIEF DESCRIPTION OF THE DRAWINGS
The accompanying photographs show typical specimens of the new variety as depicted in color as nearly true as is reasonably possible in color illustrations of this character. These specimens were obtained at the Leslie and Linda Bull farm inCasnovia, Muskegon County, Mich., 49318.
FIG. 1 illustrates the fruits of the new variety at maturity.
