Description

Latin name: Botanical classification: Fragaria x ananassa.

Varietal denomination: The varietal denomination of the claimed variety of strawberry plant is ‘DrisStrawFiftyEight’.

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 18th 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 ‘DrisStrawFiftyEight’.

Strawberry plant variety ‘DrisStrawFiftyEight’ was discovered in Kent County, the United Kingdom in July of 2011, and originated from a cross between the proprietary female parent ‘TUKE 278-050’ (unpatented) and the proprietary male parent ‘SUKE 103-064’ (unpatented). A single plant was selected and asexually propagated via stolons in the Netherlands in July of 2011.

‘DrisStrawFiftyEight’ was subsequently asexually propagated via stolons, and underwent further testing at a farm in Kent County, the United Kingdom for six years (2011 to 2016). The present variety has been found to be stable and reproduce true to type through successive asexual propagations via stolons.

‘DrisStrawFiftyEight’ exhibits the following distinguishing characteristics when grown under normal horticultural practices in Kent County, the United Kingdom:

    • 1. Significantly high yield; and
    • 2. Large fruit size.

‘DrisStrawFiftyEight’ was selected for its yield potential, fruit size, conical fruit shape, shelf-life, and flavor and eating quality of fruit.

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 three months old.

FIG. 1 illustrates whole fruit of variety ‘DrisStrawFiftyEight’.

FIG. 2 illustrates the upper surface of flowers of variety ‘DrisStrawFiftyEight’.

FIG. 3 illustrates the lower surface of flowers of variety ‘DrisStrawFiftyEight’.

FIG. 4A illustrates the lower surface of a leaf of variety ‘DrisStrawFiftyEight’.

FIG. 4B illustrates the upper surface of a leaf of variety ‘DrisStrawFiftyEight’.

 DESCRIPTION OF THE NEW VARIETY

The following detailed descriptions set forth the distinctive characteristics of ‘DrisStrawFiftyEight’. The data which define these characteristics is based on observations taken in Kent County, the United Kingdom from 2011 to 2016. 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. ‘DrisStrawFiftyEight’ has not been observed under all possible environmental conditions. The botanical description of ‘DrisStrawFiftyEight’ was taken from plants that were three 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, 2nd edition by James G. Harris and Melinda Woolf Harris, unless where otherwise defined.
