Strawberry plant named `PRESTIGE`
Abstract
This invention relates to a new and distinct variety of
strawberry plant named `PRESTIGE`. This new strawberry plant named
`PRESTIGE` is primarily adapted to the growing conditions of the
central coast of California, and is primarily characterized by its
medium to large plant size; medium fruit size; spreading calyx
segments; long petiolule length; three to four
leaflets/tri-foliate; moderate fruit production with very good
flavor; and medium green foliage with medium glossy texture and
medium interveinal blistering.

Claims
We claim:
1. A new and distinct strawberry plant named `PRESTIGE`, 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: `PRESTIGE`.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct strawberry
variety named `PRESTIGE`. This new variety is a result of a
controlled cross made in 2000 in an ongoing breeding program
between strawberry variety designated `PS-1269` (patented, U.S.
Plant Pat. No. 10,686) and strawberry variety designated `PS-3523`
(patented, U.S. Plant Pat. No. 14,447). The variety is botanically
known as Fragaria ananassa.
The seedling resulting from the aforementioned cross was selected
from a controlled breeding plot in Monterey County, California in
the summer of 2002. After its selection, the new variety was
asexually propagated by stolons in both San Joaquin County,
California and Siskiyou County, California. The new variety was
extensively tested over the next several years in fruiting fields
in Monterey County, California. 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
`PRESTIGE` 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 spring, summer and fall production months.
The following traits have been repeatedly observed and are
determined to be unique characteristics of `PRESTIGE`, which in
combination distinguish this strawberry plant as a new and distinct
variety: 1. Medium to large plant size; 2. Medium fruit size; 3.
Spreading calyx segments; 4. Long petiolule length; 5. Three to
four leaflets/tri-foliate; 6. Moderate fruit production with very
good flavor; and 7. Medium green foliage with medium glossy texture
and medium interveinal blistering.
The strawberry varieties that are believed to be most closely
related to the new strawberry variety `PRESTIGE` are the strawberry
variety `PS-592` (patented, U.S. Plant Pat. No. 9,903) and the
strawberry variety `PS-4634` (patented, U.S. Plant Pat. No. PP
17,487). In comparison to the similar strawberry varieties `PS-592`
and `PS-4634`, the new strawberry variety `PRESTIGE` differs by the
following combination of characteristics as described in Table
1:

For identification a series of AFLP molecular markers have been
determined for this new variety.
BRIEF DESCRIPTIONS OF THE PHOTOGRAPHS
The accompanying color photographs illustrate the overall
appearance of typical specimens of the new strawberry variety
`PRESTIGE`, 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 description which accurately describe the color of
`PRESTIGE`. The depicted plant and plant parts of the new
strawberry variety `PRESTIGE` were taken in Monterey County,
California, and are approximately 8 to 9 months old:
FIG. 1 shows typical fruiting field characteristics of `PRESTIGE`
taken in the month of July 2007;
FIG. 2 shows a close-up view of a typical leaf structure of
`PRESTIGE` taken in the month of July 2007;
FIG. 3 shows typical mature and immature field fruit of `PRESTIGE`
taken in the month of July 2007;
FIG. 4 shows a close-up view of mature fruit of `PRESTIGE` taken in
the month of July 2007;
FIG. 5 shows typical internal and external mature fruit
characteristics of `PRESTIGE` taken in the month of July 2007.
DETAILED BOTANICAL DESCRIPTION
`PRESTIGE` has not been observed under all possible environmental
conditions. The characteristics of the new variety 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 `PRESTIGE`, unless otherwise noted,
is based on observations taken during the 2007 growing season in
Monterey County, California. These measurements and ratings were
taken from plants of `PRESTIGE` dug from a high-elevation nursery
located in Siskiyou County, California during the middle of October
2006 and planted approximately 3 weeks later in Monterey County,
California. The approximate age of the observed plants is 8 to 10
months. Yield observations and fruit quality characteristics are
averaged from four years of data collected from the 2004 through
2007 growing seasons. Flower measurements and characteristics are
from secondary flowers unless otherwise noted. Fruit
characteristics and measurements are from secondary fruit unless
otherwise noted.
Color terminology where noted follows the Munsell Book of Colors,
Munsell Color, Baltimore Md. (1976).
The following Tables 8 describe fruit, plant, stolon, foliage,
fruiting truss, flower and pest disease characteristics of the new
strawberry `PRESTIGE` in comparison to the similar strawberry
variety `PS-592` (patented, U.S. Plant Pat. No. PP 9,903) and
strawberry variety `PS-4634 ` (patented, U.S. Plant Pat. No. PP
17,487).
