USPP33283P2 - Strawberry plant named ‘DrisStrawEightyFive’ - Google Patents

Abstract

A new and distinct variety of strawberry plant named ‘DrisStrawEightyFive’, particularly selected for its compact plant habit, good fruit quality and flavor, and early yields, is disclosed.

Description

Latin name:

Botanical classification: Fragaria x ananassa.

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

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 ‘DrisStrawEightyFive’.

Strawberry plant variety ‘DrisStrawEightyFive’ originated from a controlled cross between the proprietary female parent ‘93T154’ (unpatented) and the proprietary male parent ‘93T154’ (unpatented). More specifically, pollen from a plant of selection ‘93T154’ was used to fertilize a plant of selection ‘93T154’, and the present variety originated from this controlled cross. Progeny plants from this cross of ‘93T154’ x ‘93T154’, including ‘DrisStrawEightyFive’, were asexually propagated via stolons in Shasta County, Calif. in September of 2013. Strawberry plant variety ‘DrisStrawEightyFive’ was later specifically identified and selected in Ventura County, Calif. in October of 2014.

‘DrisStrawEightyFive’ was subsequently asexually propagated via stolons, and has undergone testing at test plots in Ventura County, Calif. for six years (2014 to 2020). The present variety has been found to be stable and reproduce true to type through successive asexual propagations via stolons and tissue culture.

‘DrisStrawEightyFive’ was particularly selected for its compact plant habit, good fruit quality and flavor, and early yields.

COMPARISON WITH PARENTAL AND REFERENCE VARIETIES

Both the male and female parent of ‘DrisStrawEightyFive’ is the proprietary strawberry selection ‘93T154’. ‘DrisStrawEightyFive’ differs from ‘93T154’ in that ‘DrisStrawEightyFive’ has more flavorful fruit, better fruit quality, and earlier production yields than ‘93T154’.

‘DrisStrawEightyFive’ differs from the reference variety ‘DrisStrawTwentySeven’ (U.S. Plant Pat. No. 23,400) in that ‘DrisStrawEightyFive’ has a upright growth habit, medium anthocyanin coloration on stolon, a cordate shaped fruit, and level with surface position of achenes on fruit, whereas ‘DrisStrawTwentySeven’ has a spreading (flat globose) growth habit, strong anthocyanin coloration on stolon, a conical shaped fruit, and below surface position of achenes on fruit.

‘DrisStrawEightyFive’ differs from the reference variety ‘DrisStrawThirtySix’ (U.S. Plant Pat. No. 25,698), in that ‘DrisStrawEightyFive’ has medium plant vigor, medium anthocyanin coloration on stipule, medium fruit glossiness, and level with surface position of achenes on fruit, whereas ‘DrisStrawThirtySix’ has very strong plant vigor, absent or very weak anthocyanin coloration on stipule, strong fruit glossiness, and below surface position of achenes on fruit.
