| Abstract: |
The `Red Topaz` apple tree originated as a spontaneous limb sport mutation discovered on a `Topaz` apple tree. `Red Topaz` is distinguishable from its parent by its fruit. `Red Topaz` has a solid red overcolor and matures about ten days earlier than `Topaz.` |
| Claim: |
It is claimed:
1. We claim a new and distinct apple tree substantially as shown and described herein. |
| Description: |
Latin name of the genus andspecies of the plant claimed: Malus domestica.
Variety denomination: `Red Topaz`.
BACKGROUND OF THE INVENTION
`Red Topaz` originated as a spontaneous mutation on a single limb of a `Topaz` apple tree (not patented), discovered by the inventors in a cultivated apple orchard in Pencin u Liberce, Czech Republic in 1998. `Red Topaz` was first asexuallypropagated by budding at Pencin u Liberce, Czech Republic in 1999, and has been shown to remain true to type over successive generations.
BRIEF SUMMARY OF THE INVENTION
`Red Topaz` is very similar to its parent `Topaz,` but is clearly distinguishable from its parent by the appearance of its fruit. `Red Topaz` develops a washed out red overcolor over its entire surface about 10 days earlier than its parent. Thered overcolor of `Topaz` typically covers only about 60 percent of the fruit surface.
`Red Topaz` can further be compared to and distinguished from `Fugachee Fuji` (U.S. Plant Pat. No. 16,270). The fruit of `Red Topaz` is similar in size and shape to the fruit of `Fugachee Fuji,` but has a brighter red overcolor than `FugacheeFuji` and is sweet-tart, as compared to the sweeter flavor of `Fugachee Fuji.` `Red Topaz` is ready for harvest about two weeks before `Fugachee Fuji.`
