| Abstract: |
A new apple tree named `Dalitron` is disclosed. The fruit of the new variety is particularly notable for its eating quality and distinctive appearance. The fruit is firm, crunchy, juicy and fully flavored, and takes on a distinctive solid bright yellow coloration during storage. `Dalitron` apples maintain favorable texture and firmness during and after long term storage. |
| Claim: |
I claim:
1. A new and distinct apple tree as described and illustrated herein. |
| Description: |
Latin name of the genus and species of the plantclaimed: Malus domestica.
Variety denomination: `Dalitron`.
BRIEF DESCRIPTION OF THE VARIETY
`Dalitron` originated from a controlled cross of seed parent `Golden Delicious` (unpatented) and pollen parent `Pilot` (not patented; French Plant Variety Rights Certificate No. 7471) at Moulin Neuf, Lezigne, France in 1994. The seedling wasselected as a single plant from among eighty-five (85) seedlings resulting from the cross, and planted in a test orchard in 1997 for evaluation. `Dalitron` was first asexually propagated in 2000 at Moulin Neuf, and has been shown to reproduce true totype through successive generations.
`Dalitron` is distinguishable from its seed parent `Golden Delicious` by its upright habit, early flowering (two days earlier than `Golden Delicious`), large, abundant leaves and flowers, bright yellow fruit coloration, and improved fruitstorageability.
`Dalitron` is distinguishable from its pollen parent `Pilot` by its large leaves and flowers, later flowering (five days after `Pilot`), and distinctive truncate-conical fruit shape.

DETAILED BOTANICAL DESCRIPTION OF THE VARIETY
The following is a detailed botanical description of `Dalitron,` based on observations of the seven year old mother tree planted in 1998, and 14 first generation trees planted in 2002, in Moulin Neuf, Lezigne, France. Colors, except those colorsdescribed in common terms, are set forth in accordance with The Royal Horticultural Society Colour Chart. The botanical characteristics described will vary somewhat depending upon cultural practices and climatic conditions, and can vary with locationand season. Quantified measurements are expressed as an average of measurements taken from a number of individual plants of the new variety. The measurements of any individual plant, or any group of plants, of the new variety may vary from the statedaverage. 1.
