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: `DrisStrawSix`.
BACKGROUND OF THE NEW PLANT
The present invention relates to a new and distinct strawberry
cultivar designated `DrisStrawSix` and botanically known as
Fragaria.times.ananassa. This new strawberry cultivar was
discovered in Hillsborough, Fla. in December, 2002 and originated
from a cross between the female proprietary parent `74G14`
(unpatented) and the male proprietary parent `6F-158` (unpatented).
The original seedling of the new cultivar was asexually propagated
at a nursery in Shasta County, Calif. `DrisStrawSix` was
subsequently asexually propagated and underwent further testing at
a nursery in Hillsborough, Fla. for five years. The present
invention has been found to retain its distinctive characteristics
through successive asexual propagations.
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.
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 the upperside 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 `DrisStrawSix` is based on
observations taken from the 2003 to 2008 growing seasons in
Hillsborough, Fla. 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. `DrisStrawSix` has not been
observed under all possible environmental conditions. Color
terminology follows The Royal Horticultural Society Colour Chart,
London (R.H.S.) (2001).
COMPARISON WITH PARENTAL LINES
`DrisStrawSix` is distinguished from its parents `74G14` or `6F158`
mainly by yield and fruit size. `DrisStrawSix` has a significantly
higher yield than either `74G14` or `6F158`. Additionally,
`DrisStrawSix` has a fruit size that is thirty percent larger than
either `74G14` or `6F158`.
