Strawberry plant named ‘DrisStrawSeventeen’

[0001] Genus and species: Fragaria×ananassa.

[0002] Variety denomination: ‘DrisStrawSeventeen’.

[0003] The present invention relates to a new and distinct strawberry variety designated ‘DrisStrawSeventeen’ and botanically known as Fragaria×ananassa. This new strawberry variety was discovered in Ventura County, Calif. in October 2006 and originated from a cross between the proprietary female parent ‘13H377’ (unpatented) and the proprietary male parent ‘119J176’ (unpatented). The original seedling of the new variety was first asexually propagated at a nursery in Shasta County, Calif. in October 2005.

[0004] ‘DrisStrawSeventeen’ was subsequently asexually propagated at a nursery in Shasta County, Calif. and underwent further testing in Ventura County, Calif. for three years (2006-2009). The present invention has been found to retain its distinctive characteristics through successive asexual propagations via stolons and tissue culture.

[0005] Plant Breeder's Rights for this variety have not been applied for. ‘DrisStrawSeventeen’ has not been made publicly available or sold more than one year prior to the filing date of this application.

[0012] The following detailed descriptions set forth the distinctive characteristics of ‘DrisStrawSeventeen’. The data which define these characteristics is based on observations taken in Ventura County, Calif. from 2006 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. ‘DrisStrawSeventeen’ has not been observed under all possible environmental conditions. The botanical description of ‘DrisStrawSeventeen’ was taken from four-month-old plants. Color terminology follows The Royal Horticultural Society Colour Chart, London (R.H.S.) (2001).
