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
`DrisStrawSixtyFour` 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 `DrisStrawSixtyFour`.
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
`DrisStrawSixtyFour`.
Strawberry plant variety `DrisStrawSixtyFour` was discovered in
Hillsborough County, Fla. in January of 2012, and originated from a
cross between the proprietary female parent `DrisStrawForty` (U.S.
Plant Pat. No. 25,747) and the proprietary male parent
`DrisStrawTwentyThree` (U.S. Plant Pat. No. 23,401). A single plant
was selected and asexually propagated via stolons in Shasta County,
Calif.
`DrisStrawSixtyFour` was subsequently asexually propagated via
stolons, and underwent further testing at a farm in Hillsborough
County, Fla. for six years (2011 to 2017). The present variety has
been found to be stable and reproduce true to type through
successive asexual propagations via stolons.
`DrisStrawSixtyFour` exhibits the following distinguishing
characteristics when grown under normal horticultural practices in
Hillsborough County, Fla.: 1. Late start of early production; and
2. Fruit having more blunt rather than pointed tips.
`DrisStrawSixtyFour` was selected for the size and shape of its
fruit; overall productivity and minimal gaps in production; flavor,
texture, and juiciness of its fruit; eating quality throughout
season; its plant vigor and health; its plant architecture; and its
long and sturdy fruit stems.
DESCRIPTION OF THE DRAWINGS
This new strawberry plant is illustrated by the accompanying
photographs which show fruit of the plant, as well as the flowers
and leaves. The colors shown are as true as can be reasonably
obtained by conventional photographic procedures. The photographs
are of plants that are four months old from time of transplant at
nursery.
FIG. 1 illustrates whole fruit of variety `DrisStrawSixtyFour`.
FIG. 2 illustrates the upper and lower surfaces of flowers of
variety `DrisStrawSixtyFour`.
FIG. 3A and FIG. 3B illustrate leaves of variety
`DrisStrawSixtyFour`.
FIG. 4 illustrates the overall plant habit including fruit at
various stages of development of variety `DrisStrawSixtyFour`.
DESCRIPTION OF THE NEW VARIETY
The following detailed descriptions set forth the distinctive
characteristics of `DrisStrawSixtyFour`. The data which define
these characteristics is based on observations taken in
Hillsborough County, Fla. from 2011 to 2017. 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.
`DrisStrawSixtyFour` has not been observed under all possible
environmental conditions. The botanical description of
`DrisStrawSixtyFour` was taken from plants that were four months
old from time of transplant at nursery. 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.
