Claims

We claim:

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

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 `DrisStrawSixtySix`.

Strawberry plant variety `DrisStrawSixtySix` originated from a cross between the proprietary female parent `DrisStrawFortyFour` (U.S. Plant Pat. No. 26,801) and the proprietary male parent `62R 83` (unpatented). Progeny plants from this cross, including `DrisStrawSixtySix`, were asexually propagated via stolons in Shasta County, Calif. in April of 2011. Strawberry plant variety `DrisStrawSixtySix` was later specifically identified and selected in Monterey County, Calif. in May of 2012.

`DrisStrawSixtySix` was subsequently asexually propagated via stolons, and underwent further testing at a farm in Santa Barbara County, Calif. for six years (2012 to 2017). The present variety has been found to be stable and reproduce true to type through successive asexual propagations via stolons.

`DrisStrawSixtySix` exhibits the following distinguishing characteristics when grown under normal horticultural practices in Santa Barbara County, Calif.: 1. Spreading growth habit; 2. Inflorescence beneath foliage; 3. Calyx attachment inserted in fruit; and 4. Day neutral type of bearing.

`DrisStrawSixtySix` was selected for its high yield, firm fruit, and compact plant type.

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 seven months old.

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

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

FIG. 3 illustrates the upper surfaces of flowers of variety `DrisStrawSixtySix`.

FIG. 4 illustrates the lower surfaces of flowers of variety `DrisStrawSixtySix`.

FIG. 5 illustrates leaves of variety `DrisStrawSixtySix`.

FIG. 6 illustrates fruit of variety `DrisStrawSixtySix` at various stages of development.

FIG. 7 illustrates plants of variety `DrisStrawSixtySix`.

DESCRIPTION OF THE NEW VARIETY

The following detailed descriptions set forth the distinctive characteristics of `DrisStrawSixtySix`. The data which define these characteristics is based on observations taken in Santa Barbara County, Calif. from 2012 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. `DrisStrawSixtySix` has not been observed under all possible environmental conditions. The botanical description of `DrisStrawSixtySix` was taken from plants that were seven 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.) (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.
