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
`DrisStrawSixtyTwo` 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 `DrisStrawSixtyTwo`.
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
`DrisStrawSixtyTwo`.
Strawberry plant variety `DrisStrawSixtyTwo` was selected in
Tapalpa, Mexico in October of 2012, and originated from a cross
between the proprietary female parent `73P176` (unpatented) and the
proprietary male parent `107P249` (unpatented). A single plant was
selected and asexually propagated via stolons in Tapalpa,
Mexico.
`DrisStrawSixtyTwo` was subsequently asexually propagated via
stolons, and underwent testing at a farm in Tapalpa, Mexico for six
years. The present variety has been found to be stable and
reproduce true to type through successive asexual propagations via
stolons.
`DrisStrawSixtyTwo` exhibits the following distinguishing
characteristics over other similar varieties when grown under
normal horticultural practices in Tapalpa, Mexico: 1. Higher yield;
2. Bearing that is partially remontant; 3. Stronger plant vigor;
and 4. Larger fruit with sweet flavor.
`DrisStrawSixtyTwo` was selected for its yield potential, fruit
size and flavor, and shelf-life.
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 six months old.
FIG. 1 illustrates whole fruit of variety `DrisStrawSixtyTwo`.
FIG. 2 illustrates longitudinal cross-sections of fruit of variety
`DrisStrawSixtyTwo`.
FIG. 3 illustrates both the upper and lower surfaces of flowers of
variety `DrisStrawSixtyTwo`.
FIG. 4A illustrates the upper surface of a leaf of variety
`DrisStrawSixtyTwo`. FIG. 4B illustrates the lower surface of a
leaf of variety `DrisStrawSixtyTwo`.
DESCRIPTION OF THE NEW VARIETY
The following detailed descriptions set forth the distinctive
characteristics of `DrisStrawSixtyTwo`. The data which define these
characteristics is based on observations taken in Tapalpa, Mexico
for six years. 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. `DrisStrawSixtyTwo` has not been
observed under all possible environmental conditions. The botanical
description of `DrisStrawSixtyTwo` was taken from plants that were
six months old. The indicated values represent averages calculated
from measurements of several plants. Color references are primarily
to The RHS Colour Chart of The Royal Horticultural Society of
London (RHS) (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.
