Primary Examiner: McCormick Ewoldt; Susan
Attorney, Agent or Firm: Morrison & Foerster LLP
Claims
We claim:
1. A new and distinct variety of strawberry plant named
`DrisStrawSeventyNine` 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 `DrisStrawSeventyNine`.
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
`DrisStrawSeventyNine`.
Strawberry plant variety `DrisStrawSeventyNine` originated from a
cross between the proprietary female parent `7R309` (unpatented)
and the proprietary male parent `92T351` (unpatented). Progeny
plants from this cross of `7R309` x `92T351`, including
`DrisStrawSeventyNine`, were asexually propagated via stolons in
McArthur, Calif., USA in April of 2013. Strawberry plant variety
`DrisStrawSeventyNine` was later specifically identified and
selected in Tapalpa, Mexico in November of 2015.
`DrisStrawSeventyNine` was subsequently asexually propagated via
stolons, and underwent further testing at test plots in
Tangancicuaro, Tapalpa, and Purepero, Mexico for four years (2015
to 2019). The present variety has been found to be stable and
reproduce true to type through successive asexual propagations via
stolons.
`DrisStrawSeventyNine` exhibits the following distinguishing
characteristics when grown under normal horticultural practices in
Tangancicuaro, Tapalpa, and Purepero, Mexico: 1. Inflorescence
beneath foliage; 2. Absent or very weak anthocyanin coloration of
stolon; 3. Obtuse shape of base of terminal leaflet; and 4. Fully
remontant type of bearing.
`DrisStrawSeventyNine` was selected for its flavor, shelf life,
fruit size, and mid-early harvest time.
DESCRIPTION OF THE DRAWINGS
This new strawberry plant is illustrated by the accompanying
photographs which show fruit of the plant, flowers, leaves, and the
plants. The colors shown are as true as can be reasonably obtained
by conventional photographic procedures. The photographs are of
plants that are seven months old.
FIG. 1 illustrates whole fruit of variety
`DrisStrawSeventyNine`.
FIG. 2 illustrates longitudinal sections of fruit of variety
`DrisStrawSeventyNine`.
FIG. 3 shows the upper and lower surfaces of flowers of variety
`DrisStrawSeventyNine`.
FIG. 4A shows the lower surface of a leaf of variety
`DrisStrawSeventyNine`. FIG. 4B shows the upper surface of a leaf
of variety `DrisStrawSeventyNine`.
FIG. 5 shows a plant of variety `DrisStrawSeventyNine`.
FIG. 6 shows plants of variety `DrisStrawSeventyNine`.
DETAILED BOTANICAL DESCRIPTION
The following detailed descriptions set forth the distinctive
characteristics of `DrisStrawSeventyNine`. The data which define
these characteristics is based on observations taken in
Tangancicuaro, Tapalpa, and Purepero, Mexico from 2015 to 2019.
This description is in accordance with UPOV terminology. Color
designations, color descriptions, and other phenotypical
descriptions may deviate from the stated values and descriptions

under all possible environmental conditions. The botanical
description of `DrisStrawSeventyNine` was taken from plants that
were seven months old. The indicated values represent averages
calculated from measurements of several plants. Color references
