Primary Examiner: Grunberg; Anne Marie
Attorney, Agent or Firm: Morrison & Foerster LLP
Claims
We claim:
1. A new and distinct variety of strawberry plant named
`DrisStrawSeventyOne` 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 `DrisStrawSeventyOne`.
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
`DrisStrawSeventyOne`.
Strawberry plant variety `DrisStrawSeventyOne` originated from a
cross between the proprietary female parent `35T 42` (unpatented)
and the proprietary male parent `50T403` (unpatented). Progeny
plants from this cross, including `DrisStrawSeventyOne`, were
asexually propagated via stolons in McArthur, Shasta County, Calif.
in April of 2012. Strawberry plant variety `DrisStrawSeventyOne`
was later specifically identified and selected in Monterey County,
Calif. in May of 2013.
`DrisStrawSeventyOne` was subsequently asexually propagated via
stolons, and underwent further testing at a farm in Monterey
County, Calif. for four years (2013 to 2017). The present variety
has been found to be stable and reproduce true to type through
successive asexual propagations via stolons.
`DrisStrawSeventyOne` exhibits the following distinguishing
characteristics when grown under normal horticultural practices in
Monterey County, Calif.: 1. Inflorescence beneath foliage; 2.
Obtuse shape of base of terminal leaflet; and 3. Partially
remontant type of bearing.
`DrisStrawSeventyOne` was selected for its growth habit, plant
health, fruit appearance, and fruit flavor.
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,
leaves and plants. The colors shown are as true as can be
reasonably obtained by conventional photographic procedures. The
photographs are of plants that are ten months old.
FIG. 1 illustrates whole fruit of variety
`DrisStrawSeventyOne`.
FIG. 2 illustrates longitudinal sections of fruit of variety
`DrisStrawSeventyOne`.
FIG. 3 shows the upper and lower surfaces of flowers of variety
`DrisStrawSeventyOne`.
FIG. 4 show leaves of variety `DrisStrawSeventyOne`.
FIG. 5 shows plants of variety `DrisStrawSeventyOne`.
DETAILED BOTANICAL DESCRIPTION OF THE PLANT
The following detailed descriptions set forth the distinctive
characteristics of `DrisStrawSeventyOne`. The data which define
these characteristics is based on observations taken in Monterey
County, Calif. from 2013 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. `DrisStrawSeventyOne`
has not been observed under all possible environmental conditions.
The botanical description of `DrisStrawSeventyOne` was taken from
plants that were ten 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.) (2015 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.

COMPARISON WITH PARENTAL AND COMMERCIAL VARIETIES
`DrisStrawSeventyOne` differs from the proprietary female parent
`35T 42` (unpatented) in that `DrisStrawSeventyOne` has larger
fruit compared to `35T 42`. Moreover, plants of
`DrisStrawSeventyOne` are more vigorous than plants of `35T 42`.
Additionally, fruit size of `35T 42` decreases more sharply later
in the season than fruit size of `DrisStrawSeventyOne`.
`DrisStrawSeventyOne` differs from the proprietary male parent
`50T403` (unpatented) in that `DrisStrawSeventyOne` has smaller,
softer, and more uniformly shaped fruit compared to `50T403`.
Moreover, `DrisStrawSeventyOne` produces fewer stolons compared to
`50T403`.
`DrisStrawSeventyOne` differs from the commercial variety
`DrisStrawFortyFour` (U.S. Plant Pat. No. 26,801) in that
`DrisStrawSeventyOne` has inflorescence beneath foliage, an obtuse
shape of base of terminal leaflet, an outwards attitude of fruit
sepals, and a partially remontant type of bearing, while
`DrisStrawFortyFour` has inflorescence above foliage, a rounded
shape of base of terminal leaflet, an upwards attitude of fruit
sepals, and a day neutral type of bearing.
`DrisStrawSeventyOne` differs from the commercial variety
`DrisStrawNine` (U.S. Plant Pat. No. 20,733) in that
`DrisStrawSeventyOne` has inflorescence beneath foliage, an obtuse
shape of base of terminal leaflet, a free arrangement of flower
petals, and a partially remontant type of bearing, whereas
