Primary Examiner: Bell; Kent L
Attorney, Agent or Firm: Morrison & Foerster LLP
Claims
We claim:
1. A new and distinct variety of strawberry plant named
`DrisStrawFiftyEight` as shown and described herein.
Description
Latin name: Botanical classification: Fragaria x ananassa.
Varietal denomination: The varietal denomination of the claimed
variety of strawberry plant is `DrisStrawFiftyEight`.
BACKGROUND OF THE INVENTION
Cultivated strawberry is a hybrid species of the genus Fragaria
that is grown worldwide for its fruit. Modern strawberry was first
bred in Brittany, France, in the 18.sup.th century by crossing
Fragaria virginiana with Fragaria chiloensis. Strawberry fruit is
an aggregate accessory fruit, with the fleshy part of the fruit
being derived from the receptacle that holds the ovaries.
Strawberry varieties vary widely in color, size, shape, flavor,
season of ripening, degree of fertility, and susceptibility to
disease. Certain varieties vary in foliage, and some vary in the
relative development of their reproductive organs. Typically,
strawberry flowers appear hermaphroditic in structure, but function
as either male or female. Generally, commercial production of
strawberry plants involves propagation from runners and
distribution as either plugs or bare root plants. Cultivation is
either perennial or annual plasticulture. During the off season,
strawberries can also be produced in greenhouses.
Strawberry fruit is widely appreciated for its characteristic
bright red color, aroma, juicy texture, and sweetness. Strawberry
fruit is a popular fruit that is generally consumed either fresh or
in prepared foods, such as preserves and baked goods.
Strawberry is an important and valuable fruit crop. Accordingly,
there is a need for new varieties of strawberry plants. In
particular, there is a need for improved varieties of strawberry
plant that are stable, high yielding, and agronomically sound.
SUMMARY OF THE INVENTION
In order to meet these needs, the present invention is directed to
an improved variety of strawberry plant. In particular, the
invention relates to a new and distinct variety of strawberry plant
(Fragaria x ananassa), which has been denominated as
`DrisStrawFiftyEight`.
Strawberry plant variety `DrisStrawFiftyEight` was discovered in
Kent County, the United Kingdom in July of 2011, and originated
from a cross between the proprietary female parent `TUKE 278-050`
(unpatented) and the proprietary male parent `SUKE 103-064`
(unpatented). A single plant was selected and asexually propagated
via stolons in the Netherlands in July of 2011.
`DrisStrawFiftyEight` was subsequently asexually propagated via
stolons, and underwent further testing at a farm in Kent County,
the United Kingdom for six years (2011 to 2016). The present
variety has been found to be stable and reproduce true to type
through successive asexual propagations via stolons.
`DrisStrawFiftyEight` exhibits the following distinguishing
characteristics when grown under normal horticultural practices in
Kent County, the United Kingdom: 1. Significantly high yield; and
2. Large fruit size.
`DrisStrawFiftyEight` was selected for its yield potential, fruit
size, conical fruit shape, shelf-life, and flavor and eating
quality of fruit.
DESCRIPTION OF THE DRAWINGS
This new strawberry plant is illustrated by the accompanying
photographs which show fruit, flowers, and leaves of the plant. The
colors shown are as true as can be reasonably obtained by
conventional photographic procedures. The photographs are of plants
that are three months old.
FIG. 1 illustrates whole fruit of variety
`DrisStrawFiftyEight`.
FIG. 2 illustrates the upper surface of flowers of variety
`DrisStrawFiftyEight`.
FIG. 3 illustrates the lower surface of flowers of variety
`DrisStrawFiftyEight`.
FIG. 4A illustrates the lower surface of a leaf of variety
`DrisStrawFiftyEight`.
FIG. 4B illustrates the upper surface of a leaf of variety
`DrisStrawFiftyEight`.
DESCRIPTION OF THE NEW VARIETY
The following detailed descriptions set forth the distinctive
characteristics of `DrisStrawFiftyEight`. The data which define
these characteristics is based on observations taken in Kent
County, the United Kingdom from 2011 to 2016. 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.
`DrisStrawFiftyEight` has not been observed under all possible
environmental conditions. The botanical description of
`DrisStrawFiftyEight` was taken from plants that were three months
old. The indicated values represent averages calculated from
measurements of several plants. Color references are primarily to
The R.H.S. Colour Chart of The Royal Horticultural Society of
London (R.H.S.) (2007 edition). Descriptive terminology follows the
Plant Identification Terminology, An Illustrated Glossary, 2.sup.nd
edition by James G. Harris and Melinda Woolf Harris, unless where
otherwise defined.
