| Abstract: |
This invention relates to a new and distinct cultivar of blueberry plant named `DrisBlueOne` primarily characterized by large berries with medium sweetness, medium acidity, and slightly oblate spherical berry shape and berries that have green flesh, is disclosed. |
| Claim: |
We claim:
1. A new and distinct cultivar of blueberry plant as described and shown herein. |
| Description: |
Genus and species: Vaccinium corymbosum.
Variety denomination: `DrisBlueOne`.
BACKGROUND OF THE NEW PLANT
The present invention relates to a new and distinct blueberry cultivar designated `DrisBlueOne` and botanically known as Vaccinium corymbosum. This new blueberry cultivar was discovered in Watsonville, Santa Cruz County, Calif. in September2000 as a result of a hybridization between the female parent, `MS7`a proprietary unpatented variety and the male parent, `Jubilee` an unpatented variety.
The original seedling of the new cultivar was asexually propagated at a nursery in Watsonville, Monterey County, Calif. `DrisBlueOne` was subsequently asexually propagated and underwent further testing at a nursery in Watsonville, Santa CruzCounty, Calif. for seven years. `DrisBlueOne` has been asexually propagated via softwood cuttings. The present invention has been found to be stable and reproduce true to type through successive asexual propagations.
SUMMARY OF THE INVENTION
The following are the most outstanding and distinguishing characteristics of this new cultivar when grown under normal horticultural practices in Watsonville, Santa Cruz County, Calif.
1. Large berries with medium sweetness;
2. Medium acidity and a slightly oblate spherical berry shape; and
3. Berries that have green flesh.
DESCRIPTION OF THE PHOTOGRAPHS
The accompanying color photographs show typical specimens of the new cultivar at various stages of development as nearly true as it is possible to make in color reproductions. The photographs are of plants that are 7 years old.
FIG. 1 shows both the upper surface and lower surface of the leaves.
FIG. 2 shows the mature flowers.
FIG. 3 shows the whole fruit and a longitudinal-section of the fruit.
DESCRIPTION OF THE NEW CULTIVAR
The following description of `DrisBlueOne` is based on observations taken from the 2007 growing season in Watsonville, Santa Cruz County, Calif., where the age of the `DrisBlueOne` plants was 7 years, while the age of the comparison variety`O'Neal` plants was 12 years old. All descriptions are in accordance with UPOV terminology. Color designations, color descriptions, and other phenotypical descriptions may deviate from the stated values and descriptions depending upon variation inenvironmental, seasonal, climatic and cultural conditions. `DrisBlueOne` has not been observed under all possible environmental conditions. Color terminology follows The Royal Horticultural Society Colour Chart, London (R.H.S.) (2001).
