Description

Latin name:

Botanical classification: Fragaria x ananassa.

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

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 ‘DrisStrawSeventyTwo’.

Strawberry plant variety ‘DrisStrawSeventyTwo’ was discovered in East Malling, Kent, United Kingdom in June of 2014, and originated from a cross between the female parent ‘UUK 125-001’ (unpatented) and the male parent ‘UUK 143-001’ (unpatented). ‘DrisStrawSeventyTwo’ was first asexually propagated via stolons in the Netherlands in July of 2014.

‘DrisStrawSeventyTwo’ was subsequently asexually propagated via stolons and underwent further testing in East Malling, Kent, United Kingdom for 5 years (2014 to 2018). The present variety has been found to be stable and reproduce true to type through successive asexual propagations via stolons.

‘DrisStrawSeventyTwo’ exhibits the following distinguishing characteristics when grown under normal horticultural practices in East Malling, Kent, the United Kingdom:

    • 1. Upright plant growth habit;
    • 2. Strong plant vigor; and
    • 3. Improved shelf life.

‘DrisStrawSeventyTwo’ was selected for its upright plant architecture, yield potential, medium fruit size, shelf life, and flavor.

DESCRIPTION OF THE DRAWINGS

This new strawberry plant is illustrated by the accompanying photographs. The colors shown are as true as can be reasonably obtained by conventional photographic procedures. The photographs are of plants that are nine to eleven months old.

FIG. 4 illustrates the lower surfaces of flowers of variety ‘DrisStrawSeventyTwo’.

FIG. 5 illustrates plants of variety ‘DrisStrawSeventyTwo’.

 DESCRIPTION OF THE NEW VARIETY

The following detailed descriptions set forth the distinctive characteristics of ‘DrisStrawSeventyTwo’. The data which define these characteristics is based on observations taken in East Malling, Kent, the United Kingdom from 2014 to 2018. 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. ‘DrisStrawSeventyTwo’ has not been observed under all possible environmental conditions. The botanical description of ‘DrisStrawSeventyTwo’ was taken from plants that were nine to eleven 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.
