1. A new and distinct cultivar of strawberry plant as described and shown herein.
Description

Genus and species: Fragaria×ananassa.

Variety denomination: ‘DrisStrawFourteen’.

BACKGROUND OF THE NEW PLANT

The present invention relates to a new and distinct strawberry cultivar designated ‘DrisStrawFourteen’ and botanically known as Fragaria×ananassa. This new strawberry cultivar was discovered in Monterey County, Calif. in May 2005 and originated from a cross between the proprietary female parent ‘159K312’ (unpatented) and the proprietary male parent ‘128K296’ (unpatented). The original seedling of the new cultivar was first asexually propagated by stolons or tissue culture at a nursery in Shasta County, Calif.

‘DrisStrawFourteen’ was subsequently asexually propagated in Shasta County, Calif. and underwent further testing in Monterey County, Calif. for five years. The present invention has been found to retain its distinctive characteristics through successive asexual propagations via stolons and tissue culture.

DESCRIPTION OF THE PHOTOGRAPHS

The accompanying color photographs show typical specimens of the new cultivar at various stages of development as nearly true as it is possible to make in color reproductions. The photographs were taken from 9-month-old plants.

FIG. 1 shows overall plant habit including fruit at various stages of development.

FIG. 2 shows leaves of the plant with three leaflets.

FIG. 3 shows both the upper side and underside of several of the flowers.

FIG. 4 shows the whole fruit.

FIG. 5 shows the fruit in longitudinal cross-section.

DESCRIPTION OF THE NEW CULTIVAR

The following description of ‘DrisStrawFourteen’ is based on observations taken in Monterey County, Calif. from 2005 to 2009. 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. ‘DrisStrawFourteen’ has not been observed under all possible environmental conditions. The botanical description of ‘DrisStrawFourteen’ was taken from 9-month-old plants and the botanical descriptions of the comparison varieties, ‘San Juan’ (U.S. Plant Pat. No. 12,899) and ‘Driscoll Lanai’ (U.S. Plant Pat. No. 15,145), were taken from 10-month-old plants and from 8-month-old plants, respectively. Color terminology follows The Royal Horticultural Society Colour Chart, London (RHS) (2001).
