Strawberry plant named `PE-7.2054`
Abstract
This invention relates to a new and distinct variety of
strawberry plant named `PE-7.2054`. This new strawberry plant named
`PE-7.2054` is primarily adapted to the growing conditions of the
central coast of California, and is primarily characterized by its
very large fruit size that is conical in shape, with very good
flavor and medium to soft flesh; high marketable yield with an
early harvest season; medium plant size with dark green, flat to
slightly convex foliage; and resistance to Fusarium wilt.

Claims
We claim:
1. A new and distinct strawberry plant named `PE-7.2054`, as herein
described and illustrated by the characteristics set forth above.
Description
Latin name of the genus and species of the plant claimed: Fragaria
ananassa.
Variety denomination: `PE-7.2054`.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct strawberry
variety named `PE-7.2054`. This new variety is a result of a
controlled cross made in 2007 in an ongoing breeding program
between strawberry variety designated `PS-5016` (U.S. Plant Pat.
No. 17,312), and strawberry selection designated `PE-1.204`
(non-patented). Due to the combining of the reciprocal seed lots,
it is unknown as to which parent variety is the seed parent and
which parent variety is the pollen parent. The variety is
botanically known as Fragaria ananassa.
The seedling resulting from the aforementioned cross was selected
from a controlled breeding plot in Ventura County, Calif. in the
fall of 2009. After its selection, the new variety was asexually
propagated by stolons in San Joaquin County, Calif. The new variety
was extensively tested over the next several years in fruiting
fields in Ventura County, Calif. This propagation has demonstrated
that the combination of traits disclosed herein as characterizing
the new variety are fixed and remain true to type through
successive generations of asexual reproduction.
BRIEF SUMMARY OF THE INVENTION
`PE-7.2054` is primarily adapted to the climate and growing
conditions of the central coast of California. The nearby Pacific
Ocean provides the needed humidity and moderate temperatures to
produce a strong vigorous plant and maintain fruit quality during
the fall production months.
The following traits have been repeatedly observed and are
determined to be unique characteristics of `PE-7.2054`, which in
combination distinguish this strawberry plant as a new and distinct
variety: 1. Very large fruit size that is conical in shape, with
very good flavor and medium to soft flesh; 2. High marketable
yield, with the harvest season considered to be early; 3. Medium
plant size, with dark green, flat to slightly convex foliage; and
4. Resistance to Fusarium wilt.
The strawberry variety that is believed to be most closely related
to the new variety `PE-7.2054` is `PE-7.2059` (U.S. Plant Pat. No.
28,756). In side-by-side comparisons to the similar strawberry
variety `PE-7.2059`, `PE-7.2054` differs by the following
combination of characteristics as described in Table 1.

BRIEF DESCRIPTIONS OF THE PHOTOGRAPHS
The accompanying color photographs illustrate the overall
appearance of typical specimens of the new strawberry variety
`PE-7.2054`, at various stages of development as true as it is
reasonably possible with color reproductions of this type. Color in
the photographs may differ slightly from the color value cited in
the botanical descriptions which accurately describe the color of
`PE-7.2054`. The depicted plant and plant parts of the new
strawberry variety `PE-7.2054` are between three and four months
old. The photographs were taken in Ventura County, Calif.:
FIG. 1 shows typical fruiting field characteristics of `PE-7.2054`,
taken in the month of November;
FIG. 2 shows a close-up view of a typical plant of `PE-7.2054`,
taken in the month of November;
FIG. 3 shows typical mature and immature field fruit of
`PE-7.2054`, taken in the month of November; and
FIG. 4 shows typical internal and external mature fruit
characteristics of `PE-7.2054`, taken in the month of November.
DETAILED BOTANICAL DESCRIPTION
The new variety `PE-7.2054` has not been observed under all
possible environmental conditions. The characteristics of the new
variety `PE-7.2054` may vary in detail, depending upon variations
in environmental factors, including weather (temperature, humidity
and light intensity), day length, soil type and location. In
addition, the characteristics of any parental variety or comparison
variety included in Tables 1, 2 and 3 of the present invention may
vary in detail, depending upon variations in environmental factors,
including weather (temperature, humidity and light intensity), day
length, soil type and location.
The aforementioned photographs, together with the following
description of the new variety `PE-7.2054`, unless otherwise noted,
are based on observations taken during the 2018 growing season in
Ventura County, Calif. These measurements and ratings were taken
from plants of `PE-7.2054` dug from a low-elevation nursery located
in San Joaquin County, Calif. during January 2018 and planted six
months later in Ventura County, Calif. The approximate age of the
observed plants is four months. Yield observations including
average weight and marketable yield, along with fruit quality
characteristics including soluble solids, are averaged from six
years of data collected from the 2013 through 2018 growing seasons.
Flower measurements and characteristics are from secondary flowers
unless otherwise noted. Fruit characteristics and measurements are
from secondary fruit unless otherwise noted.
Where noted, color terminology follows The Royal Horticultural
Society Colour Chart, London (2007).
