Description

Description

Genus and species: Fragaria×ananassa.

Variety denomination: ‘DrisStrawEleven’.

BACKGROUND OF THE NEW PLANT

The present invention relates to a new and distinct strawberry cultivar designated ‘DrisStrawEleven’ and botanically known as Fragaria×ananassa. This new strawberry cultivar was discovered in Monterey, Calif. in summer 2004 and originated from a cross between the proprietary female parent ‘122J81’ (unpatented) and the proprietary male parent ‘111H69’ (unpatented). The original seedling of the new cultivar was first asexually propagated at a nursery in Shasta County, Calif.

‘DrisStrawEleven’ was subsequently asexually propagated in Shasta County, Calif. and underwent further testing at nurseries in Monterey and San Luis Obispo, Calif. for five years. The present invention has been found to retain its distinctive characteristics through successive asexual propagations.

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 plants that were 7 months-old.

DESCRIPTION OF THE NEW CULTIVAR

The following description of ‘DrisStrawEleven’ is based on observations taken in Monterey and San Luis Obispo, Calif. from 2004–2008. 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. ‘DrisStrawEleven’ has not been observed under all possible environmental conditions. The botanical description of ‘DrisStrawEleven’ was taken from 7 month-old plants and the botanical descriptions of ‘Driscoll Lanai’ and ‘San Juan’ were taken from 7 month-old plants. Color terminology follows The Royal Horticultural Society Colour Chart, London (R.H.S.) (2001).
