Claims
We claim:
1. A new and distinct variety of strawberry plant named
`DrisStrawThirtyNine` as described and illustrated herein.
Description
Genus and species: Fragaria.times.ananassa.
Variety denomination: `DrisStrawThirtyNine`.
BACKGROUND OF THE NEW PLANT
The present invention relates to a new and distinct strawberry
variety designated `DrisStrawThirtyNine` 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 `Ophelia` (unpatented) and
the proprietary male parent `KGEM 93` (unpatented). A single plant
was selected and asexually propagated via tissue culture and
vegetative cuttings in Kent, United Kingdom in 2007.
`DrisStrawThirtyNine` underwent further testing in Kent, United
Kingdom for six years (2007-2012). 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.
`DrisStrawThirtyNine` 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 plant; 2. Conic shaped fruit; and 3. Resistance to
Verticillium wilt.
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 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 both upper and lower surfaces of the flowers.
FIG. 3 shows the whole fruit.
FIG. 4 shows the fruit in longitudinal cross-section.
FIG. 5 shows the whole plant.
DESCRIPTION OF THE NEW VARIETY
The following detailed descriptions set forth the distinctive
characteristics of `DrisStrawThirtyNine`. The data which define
these characteristics is based on observations taken in Kent,
United Kingdom from 2007 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. `DrisStrawThirtyNine`
has not been observed under all possible environmental conditions.
The botanical description of `DrisStrawThirtyNine` 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 `DrisStrawThirtyNine` is compared to the female parent
`Ophelia` (unpatented), `DrisStrawThirtyNine` has higher yields, a
higher percentage of Class 1 fruit, and better flavor and shelf
life than `Ophelia`.
When `DrisStrawThirtyNine` is compared to the male parent `KGEM 93`
(unpatented), `DrisStrawThirtyNine` is fully everbearing, whereas
`KGEM 93` is not everbearing.
When `DrisStrawThirtyNine` is compared to the commercial variety
`DrisStrawTwo` (U.S. Plant Pat. No. 18,878), `DrisStrawThirtyNine`
has a globose habit, medium leaf blistering, an obtuse terminal
leaflet base, and inflorescence positioned beneath the foliage,
whereas `DrisStrawTwo` has a flat globose habit, strong leaf
blistering, a rounded terminal leaflet base, and inflorescence
positioned above the foliage. Additionally, `DrisStrawThirtyNine`
has fruit with medium glossiness and a narrow band without achenes,
whereas `DrisStrawTwo` has fruit that is strongly glossy with a
medium band without achenes.
When `DrisStrawThirtyNine` is compared to the commercial variety
`Driscoll Camarillo` (U.S. Plant Pat. No. 14,771),
`DrisStrawThirtyNine` has leaves that are flat in cross section
with medium blistering, an obtuse base and inflorescence positioned
beneath the foliage, whereas `Driscoll Camarillo` has leaves that
are concave in cross section with very strong blistering, a rounded
base and inflorescence positioned above the foliage. Additionally,
`DrisStrawThirtyNine` has conical shaped fruit with medium
