Strawberry plant named `Driscoll Cambria`
Abstract
This invention relates to a new and distinct variety of
strawberry named `Driscoll Cambria`. The variety is similar to the
varieties `Ana Maria` and `San Juan`. The variety is distinguished
from `Ana Maria` and `San Juan`, in particular, by its absence of
bracts on leaves, weak glossiness of the leaves, globose growth
habit, density of plants, very sparse stipule pubescence, upward
petiole pose of hairs, predominantly cordate fruit shape, vary
narrow band without achenes on fruit, and the fine texture of the
fruit when tasted.

Claims
What is claimed is:
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.
1. BACKGROUND OF THE INVENTION
The new variety originated as a result of a controlled cross
between the strawberry plants `61C117` (unpatented Driscoll
variety) and `126B46` (unpatented Driscoll variety) in an ongoing
breeding program, and was discovered in a controlled breeding plot
in, Ventura County, Calif. in March 1998. The original seedling was
asexually propagated by stolons in a nursery in Shasta County,
Calif. Propagules were transplanted to a controlled breeding plot
in Ventura, County, Calif. where it was identified and selected for
further evaluation. `Driscoll Cambria` was subsequently asexually
propagated and underwent further testing at various locations in
Monterey county, Calif. for three years. 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 Cambria`. The variety is botanically
known as Fragaria.times.ananassa. The new variety is distinguished
from other varieties by a number of characteristics as set forth in
Tables 1 and 2.
3. COMPARISON TO SIMILAR VARIETIES
The varieties which we believe to be similar to `Driscoll Cambria`
from those known to use are `Ana Maria` (U.S. Plant Pat. No.
PP11,035, issued Aug. 17, 1999) and `San Juan` (U.S. Plant Pat. No.
PP12,899, issued Sep. 3, 2002). There are several characteristics
of the new variety that are different from, or not possessed by
`Ana Maria`, and `San Juan`. The new variety has a diameter of
inner calyx relative to outer on secondary flowers that is larger,
sparse stipule and petiole pubescence, many stolons, the fruiting
bodies have very narrow bands without achenes, a fine texture when
tasted, and flowers in late-February.
`Driscoll Cambria` differs from its parent `61C117` (unpatented
Driscoll variety) in several characteristics, including, but not
limited to, being adapted to Northern California climate, where
`61C117` is adapted to a Southern California climate. `Driscoll
Cambria` differs from its parent `126B46` (unpatented Driscoll
variety) in several characteristics, including, but not limited to,
having superior fruit shipability than `126B46`.
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. The plants of `Driscoll Cambria`
characterized in the botanical description and depicted in the
figures were grown outdoors in an annual production system.
Measurements were taken during the late summer in the second half
of the production season.
FIG. 1 shows leaves of the plant with three leaflets.
FIG. 2 shows the upper side and under side of the flowers.
FIG. 3 shows a close-up of the strawberry.
FIG. 4 shows the strawberry in longitudinal cross-section.
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. Observations of `Driscoll Cambria`, `Ana Maria` and
`San Juan` were taken in side by side comparison in 2002. 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. 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 in the secondary fruit
on one year old plants. Fruit and flower measurements are an
average of both primary and secondary fruit and flowers. In
particular, the reproductive structures of `Driscoll Cambria` are
fully self-fertile and typical of the species. Anther color in
yellow, 13A, pistil color is yellow, 13A, and receptacle color is
150G, yellow green.
Table 1 provides information on the plant and fruit characteristics
of the new variety `Driscoll Cambria` compared with characteristics
of `Ana Maria` and `San Juan`. Table 2 provides additional
information of the plant and fruit characteristics of the new
variety `Driscoll Cambria` compared with characteristics of the
varieties `Ana Maria` and `San Juan`. Table 3 provides reactions of
the new variety to stresses, pests, and diseases as compared to the
varieties `Ana Maria` and `San Juan`. Table 4 provides isozyme
characteristics of the new variety as compared to the varieties
`Ana Maria` and `San Juan`.

5.4 ISOZYME ANALYSIS
In addition to the morphological description above, the new
cultivar `Driscoll Cambria` has been analyzed to obtain an
indication of its genetic makeup to provide further means for
identifying the new variety and distinguishing it from some other
somewhat similar and/or related strawberry varieties. Specifically,
leaf samples of `Driscoll Cambria`, `Ana Maria` and `San Juan` were
analyzed by electrophoresis for isozyme patterns of the enzymes
phospoglucoisomerase (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.
