Strawberry Plant Named ‘drisstrawonehundredthree’

Latin name: Botanical classification: Fragaria x ananassa.

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

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 ‘DrisStrawOneHundredThree’.

Strawberry plant variety ‘DrisStrawOneHundredThree’ originated from a controlled cross between the proprietary strawberry female parent ‘94AC339’ (unpatented) and the proprietary strawberry male parent ‘104AC272’ (unpatented). Progeny plants from this cross, including ‘DrisStrawOneHundredThree’, were asexually propagated via stolons in Shasta County, Calif. in May 2016. Strawberry plant variety ‘DrisStrawOneHundredThree’ was later specifically identified and selected in Santa Barbara County, Calif. in April 2017.

‘DrisStrawOneHundredThree’ was subsequently asexually propagated via stolons, and has undergone testing at test plots in Monterey County, Calif. for four years (2018 to 2022) and Santa Barbara County, Calif. for three years (2017 to 2018 and 2020 to 2022). The present variety has been found to be stable and reproduce true to type through successive asexual propagations via stolons and tissue culture.

‘DrisStrawOneHundredThree’ was particularly selected for its yield potential, uniformity of fruit shape and size, stability of production, fruit flavor, and shelf life.
