Strawberry plant named ‘DrisStrawOne’

[0001] Genus and species: Fragaria×ananassa.

[0002] Variety denomination: ‘DrisStrawOne’.

[0003] The present invention relates to a new and distinct strawberry cultivar designated ‘DrisStrawOne’ botanically known as Fragaria×ananassa. This new strawberry cultivar originated from a controlled cross between ‘Driscoll El Capitan’ (U.S. Plant Pat. No. 14,005) and ‘Driscoll Agoura’ (U.S. Plant Pat. No. 15,731). The original seedling of the new cultivar was asexually propagated by stolons at a nursery in Shasta County, Calif. Propagules were transplanted to a controlled breeding plot in Ventura County, Calif. where it was identified and selected for further evaluation in February, 2002. ‘DrisStrawOne’ was subsequently asexually propagated and underwent further testing at various locations in Ventura County, Calif. for four years. The present invention has been found to retain its distinctive characteristics through successive asexual propagations.

[0011] The following description of ‘DrisStrawOne’ is based on observations taken during the 2006 growing season in Ventura County, Calif. 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. ‘DrisStrawOne’ has not been observed under all possible environmental conditions. Color terminology follows The Royal Horticultural Society Colour Chart, London.

Plant characteristics include plant habit, vigor, height in centimeters, diameter in centimeters, the density of an individual plant and the number of crowns per plant.
