Claims
We claim:
1. A new and distinct cultivar of strawberry plant as described and
shown herein.
Description
Genus and species: Fragaria.times.ananassa.
Variety denomination: `DrisStrawFifteen`.
BACKGROUND OF THE NEW PLANT
The present invention relates to a new and distinct strawberry
cultivar designated `DrisStrawFifteen` and botanically known as
Fragaria.times.ananassa. This new strawberry cultivar was
discovered in Monterey County, Calif. in June 2004 and originated
from a cross between the proprietary female parent `Driscoll Lanai`
(U.S. Plant Pat. No. 15,145) and the proprietary male parent
`38J181` (unpatented). The original seedling of the new cultivar
was first asexually propagated at a nursery in Shasta County,
Calif.
`DrisStrawFifteen` was subsequently asexually propagated at the
McArthur Nursery in Shasta County, Calif. and underwent further
testing in Monterey County, Calif. for six years. The present
invention has been found to retain its distinctive characteristics
through successive asexual propagations via stolons and tissue
culture.
DESCRIPTION OF THE PHOTOGRAPHS
The accompanying color photographs show typical specimens of the
new cultivar at various stages of development as nearly true as it
is possible to make in color reproductions. The photographs were
taken from 91/2-month-old plants.
FIG. 1 shows overall plant habit including fruit at various stages
of development.
FIG. 2 shows leaves of the plant with three leaflets.
FIG. 3 shows both the upper side and underside of several of the
flowers.
FIG. 4 shows the whole fruit.
FIG. 5 shows the fruit in longitudinal cross-section.
DESCRIPTION OF THE NEW CULTIVAR
The following description of `DrisStrawFifteen` is based on
observations taken in Monterey County, Calif. from 2004 to 2009.
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. `DrisStrawFifteen` has not been observed under
all possible environmental conditions. The botanical description of
`DrisStrawFifteen` was taken from 91/2-month-old plants and the
botanical descriptions of the comparison varieties, `Driscoll
Lanai` (U.S. Plant Pat. No. 15,145) and `DrisStrawNine` (U.S. Plant
Pat. No. 20,733), were taken from 10-month-old plants and from
9-month-old plants, respectively. Color terminology follows The
Royal Horticultural Society Colour Chart, London (R.H.S.)
(2001).

COMPARISON WITH PARENTAL AND COMMERCIAL CULTIVARS
When `DrisStrawFifteen` is compared to the proprietary female
parent `Driscoll Lanai` (U.S. Plant Pat. No. 15,145),
`DrisStrawFifteen` is fully everbearing while `Driscoll Lanai` is
partially everbearing. In addition, `DrisStrawFifteen` has a strong
sweetness of fruit while `Driscoll Lanai` has a medium sweetness of
fruit. Finally, `DrisStrawFifteen` has smaller fruit size (length:
3.666 cm; width: 3.492 cm) than `Driscoll Lanai` (length: 4.5 cm;
width: 3.8 cm).
When `DrisStrawFifteen` is compared to the proprietary male parent
`38J181` (unpatented), `DrisStrawFifteen` has larger fruit and is
more prone to bruising during handling than `38J181`.
When `DrisStrawFifteen` is compared to the commercial variety
`DrisStrawNine`, the petiole pose of hairs for `DrisStrawFifteen`
is outwards while the petiole pose of hairs for `DrisStrawNine` is
downward. In addition, `DrisStrawFifteen` is moderately resistant
to Verticillium wilt while `DrisStrawNine` is susceptible to
Verticillium wilt.
