Strawberry plant named `Driscoll Sausalito`
Abstract
This invention relates to a new and distinct variety of
strawberry named `Driscoll Sausalito`. The variety is similar to
the varieties `Driscoll Lanai` and `San Juan`. The variety is
distinguished from `Driscoll Lanai` and `San Juan,` in particular,
by its sweetness, acidity, internal color, longer petal length,
longer flower diameter, anythocyanin color and coloration and
moderate resistance to powdery mildew.

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 Sausalito`.
BACKGROUND OF THE INVENTION
The new variety originated as a result of a controlled cross
between the strawberry plants `San Juan` (U.S. Plant Pat. No.
12,899) and 14C185 (Unpatented Driscoll Variety) in an ongoing
breeding program, and was discovered in Monterey County, Calif. in
2000. The original seedling of the new cultivar was asexually
propagated by stolons in a Nursery in Shasta County, Calif.
Propagules were transplanted to a controlled breeding plot in
Monterey County, Calif., where the variety was identified and
selected for further evaluation. `Driscoll Sausalito` was
subsequently asexually propagated and underwent further testing in
Monterey County, Calif. for five 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.
SUMMARY OF THE INVENTION
The present invention relates to a new and distinct variety of
strawberry named `Driscoll Sausalito`. 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.
COMPARISON TO SIMILAR VARIETIES
The varieties which we believe to be similar to `Driscoll
Sausalito` from those known to us are `Driscoll Lanai` (U.S. Plant
Pat. No. 15,145) and `San Juan` (U.S. Plant Pat. No. 12,899). There
are several characteristics of the new variety that are different
from, or not possessed by `Driscoll Lanai` and `San Juan`. For
example, the new variety has a different internal color, longer
petal length, longer flower diameter, different anythocyanin color
and coloration and is moderately resistant to powdery mildew.
Additional characteristics of `Driscoll Sausalito` include an
orbicular petal shape, a rounded petal apex and an obtuse petal
base. The typical and observed petal number of `Driscoll Sausalito`
is six and the petal margin is entire. The typical and observed
sepal number of `Driscoll Sausalito` is ten. `Driscoll Sausalito`
also has a laceolate sepal shape, an acute sepal apex and a serrate
sepal margin. `Driscoll Sausalito` also has a typical and observed
broadly obviate leaflet shape and an obtuse leaflet apex. The
average number of strawberries on the fruiting truss of `Driscoll
Sausalito` is one.
`Driscoll Sausalito` is distinguished from its parent, `San Juan`
as indicated in Tables 1-4. Plants of 14C185 were not available for
side by side comparison. `Driscoll Sausalito` differs from 14C185
by having brighter red, more uniformly colored berries and superior
shelf-life.
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 under side and upper side of the flowers.
FIG. 4 shows a close-up of the fruit.
FIG. 5 shows the fruit in longitudinal cross-section.
DESCRIPTION OF THE NEW VARIETY
The following detailed description of the new variety is based upon
observations taken on plants harvested from a nursery in Shasta
country, Calif. in October, 2004 and held in cold storage until
planting in Monterey County, Calif. in November 2004. Plants were
grown in raised beds of soil under conditions typical of commercial
strawberry production in Monterey County, Calif. Observations of
`Driscoll Sausalito`, `Driscoll Lanai`, and `San Juan` were made in
side by side comparison in July 2005. Fruits were harvested twice
weekly from April, 2004 to November, 2004 for yield determination.
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.
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.
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 seven 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 Sausalito` compared with
characteristics of `Driscoll Lanai` and `San Juan`. Table 2
provides additional information of the plant and fruit
characteristics of the new variety `Driscoll Sausalito` compared
with characteristics of the varieties `Driscoll Lanai` and `San
Juan`. Table 3 provides reactions of the new variety to stresses,
pests and diseases compared with reactions of the varieties
`Driscoll Lanai` and `San Juan`. Table 4 provides isozyme
characteristics of the new variety as compared to that of the
varieties `Driscoll Lanai` and `San Juan`.

ISOZYME ANALYSIS
In addition to the morphological description above, the new
cultivar `Driscoll Sausalito` 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 Sausalito`, `Driscoll Lanai` and `San
Juan` 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.
