USPP33090P2 - Strawberry plant variety named ‘DrisStrawEightyThree’ - Google Patents

Abstract

A new and distinct variety of strawberry plant named ‘DrisStrawEightyThree’, particularly selected for the shelf-life and flavor of its fruit, high mid- to late season yield when grown in low elevation in Central Mexico, and tolerance to Xanthomonas, is disclosed.

Description

Latin name:

Botanical classification: Fragaria x ananassa.

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

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^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 ‘DrisStrawEightyThree’.

Strawberry plant variety ‘DrisStrawEightyThree’ originated from a cross between the proprietary female parent ‘50T403’ (unpatented) and the male parent ‘DrisStrawEight’ (U.S. Plant Pat. No. 20,735). Progeny plants from this cross, including ‘DrisStrawEightyThree’, were asexually propagated via stolons in Zapotlan, Jalisco, Mexico in March of 2014. Strawberry plant variety ‘DrisStrawEightyThree’ was later specifically identified and selected in Tangancicuaro, Michoacan, Mexico in December of 2014.

‘DrisStrawEightyThree’ was subsequently asexually propagated via stolons, and underwent further testing at test plots in Tangancicuaro, Michoacan, 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 and tissue culture.

‘DrisStrawEightyThree’ exhibits the following distinguishing characteristics when grown under normal horticultural practices in Tangancicuaro, Michoacan, Mexico:

• • 1. Absent or very weak anthocyanin coloration of stolon;
  • 2. Touching arrangement of petals;
  • 3. Narrow width of band without achenes on fruit; and
  • 4. Very firm fruit firmness.

‘DrisStrawEightyThree’ was particularly selected for the shelf-life and flavor of its fruit, high mid- to late season yield when grown in low elevation in Central Mexico, and tolerance to Xanthomonas.
