Strawberry plant named `Canterbury`
Abstract
This invention relates to a new and distinct variety of
strawberry named `Canterbury`. The variety is similar to the
varieties `Coronada` and `San Miguel`. The variety is distinguished
from `Coronado` and `San Miguel`, in particular, by its upright to
globose habit, very strong plant vigor, high density, obtuse shape
of the terminal leaflet base, medium to dense petiole pubescence,
its inflorescence being positioned level with the leaves, very
slight to slight difference in the shapes of the primary and
secondary fruits, absent or very weak unevenness of surface, strong
sweetness, and fine texture when tasted.

Claims
What is claimed is:
1. A new and distinct variety of strawberry plant, substantially as
shown and described.
Description
BACKGROUND OF THE INVENTION
The new variety originated as a result of a controlled cross
between the strawberry plants `9A264` (unpatented variety) and
`Balboa` (U.S. Plant Pat. No. 9,130) in an ongoing breeding
program, and was discovered as a seedling in a controlled breeding
plot, in Ventura County, Calif. in February 1996. The original
seedling of the new cultivar was asexually propagated by stolons in
McArthur, Shasta County, Calif. `Canterbury` was subsequently
asexually propagated and underwent further testing in Ventura
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.
SUMMARY OF THE INVENTION
The present invention relates to a new and distinct variety of
strawberry named `Canterbury`. 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 1-6.
COMPARISON TO SIMILAR VARIETIES
The varieties which we believe to be similar to `Canterbury` from
those known to us are `Coronado` (U.S. Plant Pat. No. 10,221) and
`San Miguel` (U.S. Plant Pat. No. 10,642). There are several
characteristics of the new variety that are different from, or not
possessed by `Coronado` and `San Miguel`. The new variety has an
upright to globose habit, very strong plant vigor, high density,
obtuse shape of the terminal leaflet base, medium to dense petiole
pubescence, its inflorescence positioned level with the leaves,
very slight to slight difference in the shapes of the primary and
secondary fruits, absent or very weak unevenness of surface, strong
sweetness, and fine texture when tasted.
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 plant.
FIG. 2 shows typical whole fruit.
DESCRIPTION OF THE NEW VARIETY
The following detailed description of the new variety is based upon
observations taken of plants and fruit grown in Ventura County,
Calif., U.S.A. Observations of `Canterbury`, `Coronado` and `San
Miguel` were taken in side by side comparison in 1999. 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.
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 and 3.
In the tables, the flowers described are secondary flowers except
where indicated. The petal color of `Canterbury` is white which is
not referenced in The R.H.S. Colour Chart. The fruit described is
the secondary fruit on one year 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 `Canterbury` compared with characteristics of
`Coronado` and `San Miguel`. Table 2 provides additional
information of the plant and fruit characteristics of the new
variety `Canterbury` compared with characteristics of the varieties
`Coronado` and `San Miguel`. Table 3 provides reactions of the new
variety to stresses as compared to the varieties `Coronado` and
`San Miguel`. The average number of stamens is 29. Anthocyanin
pigment on various plant origins is red to purple red in color. The
average number of pedicels/peduncle is 5.6. The average diameter of
a peduncle is 5.4 mm. The average length of a peduncle is 24.9 cm.
The average pedicel diameter is 1.9 mm. The average length of the
pedicels is 9.8 cm. The average petiole diameter is 4.1 mm. Achene
color is red to yellow-green (46A to 151B). The average sepal
number is 11.3 and average sepal size is 1.05 cm. Typical sugar
content, as measured by total soluble solids, is 9.5% to 10.5%. An
abundant amount of pollen produced. Tables 4 and 5 provide
information of the new variety's reaction to pests and diseases,
respectively, compared to the varieties `Coronado` and `San
Miguel`. Table 6 provides isozyme characteristics of the new
variety as compared to the varieties `Coronado` and `San
Miguel`.

ISOZYME ANALYSIS
In addition to the morphological description above, the new
cultivar `Canterbury` 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
`Canterbury`, `Coronado`, and `San Miguel` 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.
