Strawberry plant named ‘DrisStrawTwentyFour’

Abstract

A new and distinct variety of strawberry plant named ‘DrisStrawTwentyFour’ characterized by having very large sized, conical fruit with medium sweetness and high yield is disclosed.

Description

Genus and species: Fragaria×ananassa.

Variety denomination: ‘DrisStrawTwentyFour’.

BACKGROUND OF THE NEW PLANT

The present invention relates to a new and distinct strawberry variety designated ‘DrisStrawTwentyFour’ and botanically known as Fragaria×ananassa. This new strawberry variety was discovered in Hillsborough County, Fla. in December 2007 and originated from a cross between the proprietary female parent ‘3M44’ (unpatented) and the proprietary male parent ‘50L174’ (unpatented). A single plant was selected for asexual propagation via tissue culture and vegetative cuttings in Shasta County, Calif. in 2007.

‘DrisStrawTwentyFour’ underwent further testing in Hillsborough County, Fla. for five years (2007-2011). The present invention has been found to retain its distinctive characteristics through successive asexual propagations via stolons and tissue culture.

Plant Breeder's Rights for this variety have not been applied for. ‘DrisStrawTwentyFour’ has not been made publicly available or sold more than one year prior to the filing date of this application.

SUMMARY OF THE INVENTION

The following are the most outstanding and distinguishing characteristics of this new cultivar when grown under normal horticultural practices in Hillsborough County, Fla.

• • 1. High yield;
  • 2. Very large, conic shaped fruit; and
  • 3. Medium sweetness.

DESCRIPTION OF THE PHOTOGRAPHS

The accompanying color photographs show typical specimens of the new variety at various stages of development. The colors shown are as true as can be reasonably obtained by conventional photographic procedures. The photographs were taken from four-month-old plants.

DESCRIPTION OF THE NEW VARIETY

The following detailed descriptions set forth the distinctive characteristics of ‘DrisStrawTwentyFour’. The data which define these characteristics is based on observations taken in Hillsborough County, Fla. from 2007 to 2011. 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. ‘DrisStrawTwentyFour’ has not been observed under all possible environmental conditions. The botanical description of ‘DrisStrawTwentyFour’ was taken from four-month-old plants. Color references are primarily to The R.H.S. Colour Chart of The Royal Horticultural Society of London (R.H.S.) (2001 edition). Descriptive terminology follows the Plant Identification Terminology, An Illustrated Glossary, 2^nd edition by James G. Harris and Melinda Woolf Harris, unless where otherwise defined.

COMPARISON WITH PARENTAL AND COMMERCIAL VARIETIES

When ‘DrisStrawTwentyFour’ is compared to the proprietary female parent ‘3M44’ (unpatented), ‘DrisStrawTwentyFour’ has earlier production and softer fruit than ‘3M44’.

When ‘DrisStrawTwentyFour’ is compared to the proprietary male parent ‘50L174’ (unpatented), ‘DrisStrawTwentyFour’ has much higher yields than ‘50L174’.

When ‘DrisStrawTwentyFour’ is compared to the commercial variety ‘Driscoll Atlantis’ (U.S. Plant Pat. No. 16,475), ‘DrisStrawTwentyFour’ has medium glossy leaves, a slightly oblique terminal leaflet base, and thin stolons that have strong anthocyanin coloration and sparse pubescence, while ‘Driscoll Atlantis’ has weakly glossy leaves, a rounded terminal leaflet base, and medium thick stolons that have weak to medium anthocyanin coloration and medium pubescence. Additionally, ‘DrisStrawTwentyFour’ has inflorescence positioned beneath the foliage, and fruit with a broad band without achenes and a coarse texture, while ‘Driscoll Atlantis’ has inflorescence positioned level to above the foliage, and fruit with a very narrow band without achenes and a medium texture when tasted.
