Genus and species: Fragaria×ananassa.
Variety denomination: ‘DrisStrawTwentySix’.
BACKGROUND OF THE NEW PLANT
The present invention relates to a new and distinct strawberry variety designated ‘DrisStrawTwentySix’ and botanically known as Fragaria×ananassa. This new strawberry variety was discovered in Ventura County, Calif. in January 2007 and originated from a cross between the proprietary female parent ‘18L33’ (unpatented) and the proprietary male parent ‘193M68’ (unpatented). A single plant was selected for asexual propagation via tissue culture and vegetative cuttings in Shasta County, Calif. in 2007.
‘DrisStrawTwentySix’ underwent further testing in Ventura County, Calif. for five years (2007-2011). The present invention has been found to retain its distinctive characteristics through successive asexual propagations via stolons.
Plant Breeder's Rights for this variety have not been applied for. ‘DrisStrawTwentySix’ 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 Ventura County, Calif.
- 1. High yield;
- 2. Large, conic shaped fruit; and
- 3. Very early 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 six-month-old plants.

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. ‘DrisStrawTwentySix’ has not been observed under all possible environmental conditions. The botanical description of ‘DrisStrawTwentySix’ was taken from six-month-old plants. Color terminology follows The Royal Horticultural Society Colour Chart (R.H.S.), London (2001 edition). Descriptive terminology follows the Plant Identification Terminology, An Illustrated Glossary, 2nd edition by James G. Harris and Melinda Woolf Harris, unless where otherwise defined.

Additionally, ‘DrisStrawTwentySix’ has thick stolons and a broad band without achenes, while ‘Driscoll El Dorado’ has thin stolons and a narrow to medium band without achenes.
When ‘DrisStrawTwentySix’ is compared to the commercial variety ‘DrisStrawEight’ (U.S. Plant Pat. No. 20,735), ‘DrisStrawTwentySix’ has a flat globose habit that is not everbearing, with strongly glossy leaves, a flat terminal leaflet margin and an oval terminal leaflet shape, while ‘DrisStrawEight’ has a globose habit that is partially everbearing, with weakly glossy leaves, a revolute terminal leaflet margin and an orbicular terminal leaflet shape.
