Strawberry plant named ‘DrisStrawFortyOne’

Abstract

A new and distinct variety of strawberry plant named ‘DrisStrawFortyOne’ particularly characterized by a dense plant bearing dark red fruit having a mid-season harvest maturity is disclosed.

Description

Genus and species: Fragaria×ananassa.

Variety denomination: ‘DrisStrawFortyOne’.

BACKGROUND OF THE NEW PLANT

The present invention relates to a new and distinct strawberry variety designated ‘DrisStrawFortyOne’ and botanically known as Fragaria×ananassa. This new strawberry variety was discovered in Monterey County, Calif. in June 2008 and originated from a cross between the proprietary female parent ‘131N177’ (unpatented) and the proprietary male parent ‘142N322’ (unpatented). A single plant was selected for asexual propagation via tissue culture and vegetative cuttings in Shasta County, Calif. in 2008.

‘DrisStrawFortyOne’ underwent further testing in Monterey County, Calif. for six years (2008-2013). 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. ‘DrisStrawFortyOne’ has not been made publicly available or sold anywhere in the world 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 Monterey County, Calif.

• • 1. Dense plant;
  • 2. Dark red fruit; and
  • 3. Mid-season harvest maturity.

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 eight-month-old plants.

FIG. 1 shows upper and lower surfaces of the leaves of the plant with three leaflets.

FIG. 2 shows both upper and lower surfaces of the flowers.

FIG. 3 shows the whole fruit.

FIG. 4 shows the fruit in longitudinal cross-section.

FIG. 5 shows the whole plant.

DESCRIPTION OF THE NEW VARIETY

The following detailed descriptions set forth the distinctive characteristics of ‘DrisStrawFortyOne’. The data which define these characteristics is based on observations taken in Monterey County, Calif. from 2008 to 2013. 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. ‘DrisStrawFortyOne’ has not been observed under all possible environmental conditions. The botanical description of ‘DrisStrawFortyOne’ was taken from eight-month-old plants. Color references are primarily to The R.H.S. Colour Chart of The Royal Horticultural Society of London (R.H.S.) (2007 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.
