USPP36665P2 - Strawberry plant named ‘DrisStrawOneHundredEight’ - Google Patents

Abstract

A new and distinct variety of strawberry plant named ‘DrisStrawOneHundredEight’, particularly selected for the yield potential and vigor of the plant, as well as the fruit flavor and quality, is disclosed.

Description

Latin name: Botanical classification: Fragaria x ananassa.

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

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 ‘DrisStrawOneHundredEight’.

Strawberry plant variety ‘DrisStrawOneHundredEight’ was selected in Huelva, Spain in February 2020 and originated from a controlled cross between the female parent proprietary strawberry plant ‘FS201.027’ (unpatented) and the male parent ‘DrisStrawSeventyThree’ (U.S. Plant Pat. No. 32,305). The original seedling of ‘DrisStrawOneHundredEight’ was first asexually propagated via cuttings in Valladolid, Spain in May 2020.

‘DrisStrawOneHundredEight’ was subsequently asexually propagated via cuttings, and has undergone testing at test plots in Moulay Bousselham, Morocco for three years (2021 to 2024). The present variety has been found to be stable and reproduce true to type through successive asexual propagations via cuttings and tissue culture.

‘DrisStrawOneHundredEight’ was particularly selected for the yield potential and vigor of the plant, as well as the fruit flavor and quality.
