Claims
We claim:
1. A new and distinct variety of strawberry plant named
`DrisStrawThirtyOne` as described and shown herein.
Description
Genus and species: Fragaria.times.ananassa.
Variety denomination: `DrisStrawThirtyOne`.
BACKGROUND OF THE NEW PLANT
The present invention relates to a new and distinct strawberry
variety designated `DrisStrawThirtyOne` and botanically known as
Fragaria.times.ananassa. This new strawberry variety was discovered
in Ventura County, Calif. in October 2007 and originated from a
cross between the proprietary female parent `DrisStrawThree` (U.S.
Plant Pat. No. 19,673) and the proprietary male parent `508M172`
(unpatented). A single plant was selected for asexual propagation
via tissue culture and vegetative cuttings in Shasta County, Calif.
in 2007.
`DrisStrawThirtyOne` underwent further testing in Ventura County,
Calif. 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.
`DrisStrawThirtyOne` 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 Ventura County, Calif. 1. Large fruit
with sweet juicy flavor; 2. Conic shape; and 3. Full red glossy
color.
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 `DrisStrawThirtyOne`. The data which define
these characteristics is based on observations taken in Ventura
County, Calif. 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. `DrisStrawThirtyOne`
has not been observed under all possible environmental conditions.
The botanical description of `DrisStrawThirtyOne` was taken from
four-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 `DrisStrawThirtyOne` is compared to the proprietary female
parent `DrisStrawThree` (U.S. Plant Pat. No. 19,673),
`DrisStrawThirtyOne` has an upright habit with medium density,
medium glossy leaves, and conical shaped fruit, whereas
`DrisStrawThree` has a dense, flat globose habit, weakly glossy
leaves, and almost cylindrical shaped fruit. Additionally,
`DrisStrawThirtyOne` has a earlier fruiting and firmer fruit than
`DrisStrawThree`.
When `DrisStrawThirtyOne` is compared to the proprietary male
parent `508M172` (unpatented), `DrisStrawThirtyOne` has a more
compact plant habit, larger and darker fruit, better rain
tolerance, and higher yield than `508M172`.
When `DrisStrawThirtyOne` is compared to the commercial variety
`DrisStrawTwentyOne` (U.S. Plant Pat. No. 23,506),
`DrisStrawThirtyOne` has medium dense plants with weak leaf
blistering and medium stolon number, whereas `DrisStrawTwentyOne`
has dense plants with medium leaf blistering and few stolons.
