Strawberry plant named ‘DrisStrawNineteen’

Abstract

A new and distinct variety of strawberry plant named ‘DrisStrawNineteen’ characterized by having medium sized, conical to bi-conical shaped berries that are medium red in color, and having a medium to strong sweetness, is disclosed.

Description

Genus and species: Fragaria×ananassa.

Variety denomination: ‘DrisStrawNineteen’.

BACKGROUND OF THE NEW PLANT

The present invention relates to a new and distinct strawberry variety designated ‘DrisStrawNineteen’ and botanically known as Fragaria×ananassa. This new strawberry variety was the result of a controlled cross conducted in Hillsborough, Fla. in 2004 between the proprietary female parent ‘Driscoll Atlantis’ (U.S. Plant Pat. No. 16,475) and the proprietary male parent ‘43J313’ (unpatented). A single plant was selected for asexual propagation via tissue culture and vegetative cuttings in Shasta County, Calif. in 2005.

‘DrisStrawNineteen’ underwent further testing in Hillsborough, Fla. for seven years (2004-2011). The present invention has been found to retain its distinctive characteristics through several asexual propagations via stolons.

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

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 ‘DrisStrawNineteen’. The data which define these characteristics is based on observations taken in Hillsborough, Fla. from 2004 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. ‘DrisStrawNineteen’ has not been observed under all possible environmental conditions. The botanical description of ‘DrisStrawNineteen’ was taken from four-month-old plants. Color terminology follows The Royal Horticultural Society Colour Chart, London (R.H.S.) (2001).
