Attorney, Agent or Firm: Morrison & Foerster LLP

Claims

We claim:

1. A new and distinct variety of strawberry plant named `DrisStrawSeventy` 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 `DrisStrawSeventy`.

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 `DrisStrawSeventy`.

Strawberry plant variety `DrisStrawSeventy` originated from a cross between the proprietary female parent `139T272` (unpatented) and the male parent `DrisStrawTwentyFour` (U.S. Plant Pat. No. 23,378). Progeny plants from this cross, including `DrisStrawSeventy`, were asexually propagated via stolons in McArthur, Shasta County, Calif. in September of 2012. Strawberry plant variety `DrisStrawSeventy` was later specifically identified and selected in Hillsborough County, Fla. in January of 2013.

`DrisStrawSeventy` was subsequently asexually propagated via stolons, and underwent further testing at a farm in Hillsborough County, Fla. for six years (2013 to 2018). The present variety has been found to be stable and reproduce true to type through successive asexual propagations via stolons.

`DrisStrawSeventy` exhibits the following distinguishing characteristics when grown under normal horticultural practices in Hillsborough County, Fla.: 1. Semi-upright plant growth habit; 2. Inflorescence above foliage; and 3. Calyx attachment level with fruit.

`DrisStrawSeventy` was selected for its fruit size, consistency of size and shape of fruit, fruit glossiness and appearance, fruit eating quality, flavor, and texture, partially remontant type of bearing with yield from both early and late fruiting, plant architecture, plant vigor, and long fruit trusses.

DESCRIPTION OF THE DRAWINGS

This new strawberry plant is illustrated by the accompanying photographs which show fruit of the plant, flowers, leaves, and plants in the field. The colors shown are as true as can be reasonably obtained by conventional photographic procedures. The photographs are of plants that are four months from time of transplant at nursery.

FIG. 1 illustrates whole fruit of variety `DrisStrawSeventy`.

FIG. 2 illustrates longitudinal sections of fruit of variety `DrisStrawSeventy`.

FIG. 3 shows the upper and lower surfaces of flowers of variety `DrisStrawSeventy`.

FIG. 4 shows the upper surface of leaves of variety `DrisStrawSeventy`.

FIG. 5 illustrates fruit of variety `DrisStrawSeventy` at different maturation stages.

FIG. 6 illustrates plants of variety `DrisStrawSeventy`.

FIG. 7 illustrates a field of variety `DrisStrawSeventy`.

COMPARISON WITH PARENTAL AND COMMERCIAL VARIETIES

`DrisStrawSeventy` differs from the proprietary female parent `139T272` (unpatented) in that `DrisStrawSeventy` is more vigorous and begins production earlier than `139T272`. In addition, fruit of `DrisStrawSeventy` are larger, softer, lighter in color, and have a more consistent and conic shape than fruit of `139T272`.

`DrisStrawSeventy` differs from the male parent and commercial variety `DrisStrawTwentyFour` (U.S. Plant Pat. No. 23,378) in that `DrisStrawSeventy` has a semi-upright plant growth habit, inflorescence above foliage, achenes level with fruit surface, and calyx attachment level with fruit, whereas `DrisStrawTwentyFour` has a spreading plant growth habit, inflorescence beneath foliage, achenes above fruit surface, and calyx attachment raise from fruit. Further, production of `DrisStrawSeventy` begins a few days later than `DrisStrawTwentyFour`, and even though early yield of `DrisStrawSeventy` does not typically reach the level of `DrisStrawTwentyFour`, `DrisStrawSeventy` tends to meet or exceed `DrisStrawTwentyFour` for late and total yield by end of March. Moreover, fruit of `DrisStrawSeventy` are larger, and has better shelf life and flavor than fruit of `DrisStrawTwentyFour`.

`DrisStrawSeventy` differs from the commercial variety `DrisStrawSixtyFour` (U.S. Plant Pat. No. 30,936) in that `DrisStrawSeventy` has a semi-upright plant growth habit, an obtuse shape of base of terminal leaflet, a straight shape in cross section of terminal leaflet, and calyx attachment level with fruit, whereas `DrisStrawSixtyFour` has a spreading growth habit, a rounded shape of base of terminal leaflet, a concave shape in cross section of terminal leaflet, and calyx attachment inserted in fruit.

`DrisStrawSeventy` differs from the commercial variety `DrisStrawFortyNine` (U.S. Plant Pat. No. 27,682) in that `DrisStrawSeventy` has a semi-upright plant growth habit, an obtuse shape of base of terminal leaflet, a straight shape in cross section of terminal leaflet, and calyx attachment level with fruit, whereas `DrisStrawFortyNine` has a semi-upright to spreading plant growth habit, a rounded shape of base of terminal leaflet, a concave to straight shape in cross section of terminal leaflet, and calyx attachment inserted in fruit.
