Claims
We claim:
1. A new and distinct variety of strawberry plant named
`DrisStrawTwentyThree` as described and shown herein.
Description
Genus and species: Fragaria.times.ananassa.
Variety denomination: `DrisStrawTwentyThree`.
BACKGROUND OF THE NEW PLANT
The present invention relates to a new and distinct strawberry
variety designated `DrisStrawTwentyThree` and botanically known as
Fragaria.times.ananassa. This new strawberry variety was discovered
in Hillsborough County, Fla. in December 2007 and originated from a
cross between the proprietary female parent `1M16` (unpatented) and
the proprietary male parent `87K286` (unpatented). A single plant
was selected for asexual propagation via tissue culture and
vegetative cuttings in Shasta County, Calif. in 2007.
`DrisStrawTwentyThree` underwent further testing in Hillsborough
County, Fla. for five years (2007-2011). The present invention has
been found to retain its distinctive characteristics through
successive asexual propagations via stolons.
Plant Breeder's Rights for this variety have not been applied for.
`DrisStrawTwentyThree` has not been made publicly available or sold
more than one year prior to the filing date of this
application.
SUMMARY OF THE INVENTION
The following are the most outstanding and distinguishing
characteristics of this new cultivar when grown under normal
horticultural practices in Hillsborough County, Fla. 1. High yield;
2. Very large, bi-conic shaped fruit; and 3. Medium sweetness.
DESCRIPTION OF THE PHOTOGRAPHS
The accompanying color photographs show typical specimens of the
new variety at various stages of development. The colors shown are
as true as can be reasonably obtained by conventional photographic
procedures. The photographs were taken from four-month-old
plants.
FIG. 1 shows overall plant habit including fruit at various stages
of development.
FIG. 2 shows upper and lower surfaces of the leaves of the plant
with three leaflets.
FIG. 3 shows both upper and lower surfaces of the flowers.
FIG. 4 shows the whole fruit.
FIG. 5 shows the fruit in longitudinal cross-section.
DESCRIPTION OF THE NEW VARIETY
The following detailed descriptions set forth the distinctive
characteristics of `DrisStrawTwentyThree`. The data which define
these characteristics is based on observations taken in
Hillsborough County, Fla. from 2007 to 2011. This description is in
accordance with UPOV terminology. Color designations, color
descriptions, and other phenotypical descriptions may deviate from
the stated values and descriptions depending upon variation in
environmental, seasonal, climatic, and cultural conditions.
`DrisStrawTwentyThree` has not been observed under all possible
environmental conditions. The botanical description of
`DrisStrawTwentyThree` was taken from four-month-old plants. Color
terminology follows The Royal Horticultural Society Colour Chart,
London (R.H.S.) (2001 edition). Descriptive terminology follows the
Plant Identification Terminology, An Illustrated Glossary, 2.sup.nd
edition by James G. Harris and Melinda Woolf Harris, unless where
otherwise defined.

COMPARISON WITH PARENTAL AND COMMERCIAL VARIETIES
When `DrisStrawTwentyThree` is compared to the proprietary female
parent `1M16` (unpatented), `DrisStrawTwentyThree` has higher
yields and larger fruit than `1M16`.
When `DrisStrawTwentyThree` is compared to the proprietary male
parent `87K286` (unpatented), `DrisStrawTwentyThree` has much
higher yields than. `87K286`.
When `DrisStrawTwentyThree` is compared to the commercial variety
`Driscoll Sanibel` (U.S. Plant Pat. No. 16,298),
`DrisStrawTwentyThree` has a revolute terminal leaflet margin
profile, a rounded terminal leaflet base, and stolons with absent
or very weak anthocyanin coloration, while `Driscoll Sanibel` has a
flat terminal leaflet margin profile, an obtuse terminal leaflet
base, and stolons with strong anthocyanin coloration. Additionally,
`DrisStrawTwentyThree` has bi-conical shaped fruit with a very
broad band without achenes and a coarse texture on a plant that is
not everbearing, while `Driscoll Sanibel` has conical shaped fruit
with a narrow band without achenes and a fine texture on a plant
that is partially everbearing.
