Claims
We claim:
1. A new and distinct variety of strawberry plant named
`DrisStrawTwentyEight` as described and shown herein.
Description
Genus and species: Fragaria.times.ananassa.
Variety denomination: `DrisStrawTwentyEight`.
BACKGROUND OF THE NEW PLANT
The present invention relates to a new and distinct strawberry
variety designated `DrisStrawTwentyEight` and botanically known as
Fragaria.times.ananassa. This new strawberry variety was discovered
in Monterey County, Calif. in July 2007 and originated from a cross
between the proprietary female parent `95L299` (unpatented) and the
proprietary male parent `251M27` (unpatented). A single plant was
selected for asexual propagation via tissue culture and vegetative
cuttings in Shasta County, Calif. in 2007.
`DrisStrawTwentyEight` underwent further testing in Monterey
County, Calif. for five years (2007-2011). The present invention
has been found to retain its distinctive characteristics through
successive asexual propagations via stolons and tissue culture.
Plant Breeder's Rights for this variety have not been applied for.
`DrisStrawTwentyEight` 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 Monterey County, Calif. 1. High yield;
2. Medium sized, 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 eight-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 `DrisStrawTwentyEight`. The data which define
these characteristics is based on observations taken in Monterey
County, Calif. 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. `DrisStrawTwentyEight`
has not been observed under all possible environmental conditions.
The botanical description of `DrisStrawTwentyEight` was taken from
eight-month-old plants. Color references are primarily to The
R.H.S. Colour Chart of The Royal Horticultural Society of 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 `DrisStrawTwentyEight` is compared to the proprietary female
parent `95L299` (unpatented), `DrisStrawTwentyEight` is higher
yielding and has larger fruit than `95L299`.
When `DrisStrawTwentyEight` is compared to the proprietary male
parent `251M27` (unpatented), `DrisStrawTwentyEight` has better
shelf life, better flavor and better yields than `251M27`.
When `DrisStrawTwentyEight` is compared to the commercial variety
`San Juan` (U.S. Plant Pat. No. 12,899), `DrisStrawTwentyEight` has
strong plant vigor, a concave leaf shape in cross section and only
three leaflets, while `San Juan` has medium plant vigor, a flat to
slightly convex leaf shape in cross section, and sometimes more
than three leaflets. Additionally, `DrisStrawTwentyEight` has a
long fruiting truss, and fruit with a medium sized band without
achenes and small hollow center, while `San Juan` has a medium
length fruiting truss, and fruit with a narrow band without achenes
and a medium sized hollow center.
When `DrisStrawTwentyEight` is compared to the commercial variety
`DrisStrawNine` (U.S. Plant Pat. No. 20,733),
`DrisStrawTwentyEight` has a flat globose habit with strong vigor,
and terminal leaflets with crenate margins, while `DrisStrawNine`
has an upright habit with weak vigor, and terminal leaflets with
flat margins. Additionally, `DrisStrawTwentyEight` has a long
fruiting truss with a prostate attitude on a partially everbearing
plant, while `DrisStrawNine` has a medium length fruiting truss
with a semi-erect attitude on a fully everbearing plant.
