Claims
We claim:
1. A new and distinct variety of strawberry plant named
`DrisStrawThirtyEight` as described and illustrated herein.
Description
Genus and species: Fragaria.times.ananassa.
Variety denomination: `DrisStrawThirtyEight`.
BACKGROUND OF THE NEW PLANT
The present invention relates to a new and distinct strawberry
variety designated `DrisStrawThirtyEight` and botanically known as
Fragaria.times.ananassa. This new strawberry variety was discovered
in Kent, United Kingdom in August 2007 and originated from a cross
between the proprietary female parent `Driscoll Jubilee` (U.S.
Plant Pat. No. 15,435) and the proprietary male parent `Canterbury`
(U.S. Plant Pat. No. 12,577). A single plant was selected and
asexually propagated via tissue culture and vegetative cuttings in
Kent, United Kingdom in 2007.
`DrisStrawThirtyEight` underwent further testing in Kent, United
Kingdom for five years (2008-2012). 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.
`DrisStrawThirtyEight` has not been made publicly available or sold
anywhere in the world 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 Kent, United Kingdom. 1. Fully
everbearing; 2. Vigorous, high yielding plants; and 3. Firm, medium
red fruit.
DESCRIPTION OF THE PHOTOGRAPH
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 five to six month-old
plants.
FIG. 1 shows upper and lower surfaces of the leaves of the plant
with three leaflets.
FIG. 2 shows the upper and lower surfaces of the flowers.
FIG. 3 shows whole plants with flowers and fruit.
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 `DrisStrawThirtyEight`. The data which define
these characteristics is based on observations taken in Kent,
United Kingdom from 2008 to 2012. 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. `DrisStrawThirtyEight`
has not been observed under all possible environmental conditions.
The botanical description of `DrisStrawThirtyEight` was taken from
five to six month-old plants. Color references are primarily to The
R.H.S. Colour Chart of The Royal Horticultural Society of London
(R.H.S.) (2007 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 `DrisStrawThirtyEight` is compared to the female parent plant
`Driscoll Jubilee` (U.S. Plant Pat. No. 15,435),
`DrisStrawThirtyEight` has much higher fruit yield, heavier stipule
pubescence, and firmer fruit than `Driscoll Jubilee`.
When `DrisStrawThirtyEight` is compared to the male parent plant
`Canterbury` (U.S. Plant Pat. No. 12,577), `DrisStrawThirtyEight`
is more vigorous, and has smaller, less sweet, and more acidic
fruit than `Canterbury`.
When `DrisStrawThirtyEight` is compared to the commercial variety
`DrisStrawTwo` (U.S. Plant Pat. No. 18,878), `DrisStrawThirtyEight`
has medium leaf blistering, absent or very weak stolon anthocyanin
coloration, and an absent or very narrow width of band without
achenes, whereas `DrisStrawTwo` has strong leaf blistering, strong
stolon anthocyanin coloration, and a medium width of band without
achenes. Additionally, `DrisStrawThirtyEight` has weak fruit
glossiness, whereas `DrisStrawTwo` has strong fruit glossiness.
When `DrisStrawThirtyEight` is compared to the commercial variety
`Driscoll Camarillo` (U.S. Plant Pat. No. 14,771),
`DrisStrawThirtyEight` has an average of 3 crowns per plant, a
medium plant density and conical shaped fruit with weak glossiness,
whereas `Driscoll Camarillo` has an average of 4.8 crowns per
plant, an open plant density and cordate shaped fruit with strong
glossiness.
