Strawberry plant named `Driscoll Jubilee`
Abstract
This invention relates to a new and distinct variety of
strawberry named `Driscoll Jubilee.` The variety is similar to the
varieties `Driscoll Camarillo` and `Driscoll Coronation.` The
variety is distinguished from `Driscoll Camarillo` and `Driscoll
Coronation,` in particular, by its smaller spread of plant, conic
shaped fruit of greater length than width, thinner stolons, red and
white internal fruit color, the shape of the base of the terminal
leaflets is acute, and the inflorescence is beneath the
foliage.

Claims
What is claimed:
1. A new and distinct variety of strawberry plant, substantially as
shown and described.
Description
Latin name of the genus and species of the plant claimed: The
variety is botanically identified as Fragaria.times.ananassa.
Variety denomination: The strawberry variety denomination is
`Driscoll Jubilee`.
1. BACKGROUND OF THE INVENTION
The new variety originated as a result of a controlled cross
between the strawberry plants `50C130` (unpatented variety) and
`19A331` (unpatented variety) in an ongoing breeding program, and
was discovered as a seedling in Kent, England in 1999. The original
seedling of the new cultivar was asexually propagated by stolons in
a Nursery in Kent, England. Propagules were transplanted to a
controlled breeding plot in Monterey, Calif., where the variety was
identified and selected for further evaluation. `Driscoll Jubilee`
was subsequently asexually propagated and underwent further testing
in Monterey, Calif. for one year. This propagation and testing has
demonstrated that the combination of traits disclosed herein which
characterize the new variety are fixed and retained true to type
through successive generations of asexual reproduction.
2. SUMMARY OF THE INVENTION
The present invention relates to a new and distinct variety of
strawberry named `Driscoll Jubilee.` The variety is botanically
identified as Fragaria.times.ananassa. The new variety is
distinguished from other varieties by a number of characteristics
as set forth in Tables 1-4.
3. COMPARISON TO SIMILAR VARIETIES
The varieties which we believe to be similar to `Driscoll Jubilee`
from those known to us are `Driscoll Camarillo` (U.S. Plant Pat.
No. 14,771) and `Driscoll Coronation` (U.S. Plant patent
application Ser. No. 10/619,692). These are several characteristics
of the new variety that are different from, or not possessed by
`Driscoll Camarillo` and `Driscoll Coronation`. The new variety has
a smaller spread of plant, conic shaped fruit of greater length
than width, thinner stolons, red and white internal fruit color,
the shape of the base of the terminal leaflets is acute, and the
inflorescence is beneath the foliage. The internal fruit color of
`Driscoll Jubilee` and `Driscoll Camarillo` comprises a white color
interspersed in a striped manner among the orange-red or red color
described for each variety. Each color described for the internal
fruit color of `Driscoll Camarillo` and `Driscoll Jubilee` is
individually present in the internal fruit tissues. In contrast,
the internal fruit color of `Driscoll Coronation` is whitish.
`Driscoll Jubilee` is distinguished from its maternal parent
`50C130` by its smaller fruit size, firmer flesh, and its fully
everbearing habit. `Driscoll Jubilee` is distinguished from its
paternal parent `19A331` by its redder external fruit color, firmer
flesh, and sweeter taste.
4. BRIEF DESCRIPTION OF THE DRAWINGS
The accompanying photographs show typical specimens of the new
variety, including fruit, foliage and flowers, in color as nearly
true as it is reasonably possible to make in color illustrations of
these characteristics.
FIG. 1 shows the whole the plant.
FIG. 2 shows the upper side of the leaves of the plant.
FIG. 3 shows the upper side and underside of the flowers.
FIG. 4 shows the fruit in longitudinal cross-section.
FIG. 5 shows a close-up of the fruit.
5. DESCRIPTION OF THE NEW VARIETY
The following detailed description of the new variety is based upon
observations taken of plants and fruit grown in Monterey County,
Calif., U.S.A. This description is in accordance with UPOV
terminology. Observations of `Driscoll Jubilee`, `Driscoll
Camarillo` and `Driscoll Coronation` were taken in side by side
comparison in the year 2002. Plants for observation were harvested
from a low elevation nursery in Tehama County, Calif. in December
2001, and held in refrigerated storage until planting in Monterey
County, Calif. in March 2002. Plants were grown in raised beds of
soil under conditions typical of commercial strawberry production
along the central coast of California. Fruits were harvested twice
weekly for yield determination from May to October 2002.
Measurements of plant, flower, and fruit characteristics were made
in August 2002, approximately five months after planting. 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. Colors are described and the most similar
color designations are provided from The Royal Horticultural
Society (R.H.S.) Colour Chart.
5.1 PROPAGATION
The new variety is principally propagated by way of stolons.
Although propagation by stolons is presently preferred, other known
methods of propagating strawberry plants may be employed.
5.2 CHARACTERISTICS OF THE NEW VARIETY
Information on the new variety is presented in Tables 1, 2, 3 and
4. In the tables, the flowers described are secondary flowers
except where indicated. The fruit described is the secondary fruit
on five month old plants. Fruit and flower measurements are an
average of both primary and secondary fruit and flowers.
Table 1 provides information on the plant and fruit characteristics
of the new variety `Driscoll Jubilee` compared with characteristics
of `Driscoll Camarillo` and `Driscoll Coronation.` Table 2 provides
additional information of the plant and fruit characteristics of
the new variety `Driscoll Jubilee` compared with characteristics of
the varieties `Driscoll Camarillo` and `Driscoll Coronation.` Table
3 provides reactions of the new variety to stresses, pests and
diseases compared with reactions of the varieties `Driscoll
Camarillo` and `Driscoll Coronation.` Table 4 provides isozyme
characteristics of the new variety as compared to that of the
varieties `Driscoll Camarillo` and `Driscoll Coronation.`

5.4 ISOZYME ANALYSIS
In addition to the morphological description above, the new
cultivar `Driscoll Jubilee` has been analyzed to obtain an
indication of its genetic makeup to provide further means for
identifying the new variety and distinguishing it from other
somewhat similar and/or related strawberry varieties. Specifically,
leaf samples of `Driscoll Jubilee`, `Driscoll Camarillo` and
`Driscoll Coronation` were analyzed by electrophoresis for isozyme
patterns of the enzymes phosphoglucoisomerase ("PGI"), leucine
aminopeptidase ("LAP") and phosphoglucomutase ("PGM"). See J. Amer.
Soc. Hort. Sci. 106:684-687. Isozyme characterization of the three
varieties is presented in Table 4, with the letters representing
the banding patterns for each enzyme as designated in the
above-identified article.
