USPP20248P3 - Strawberry plant named ‘DrisStrawFive’ - Google Patents

Abstract

This invention relates to a new and distinct cultivar of strawberry plant named ‘DrisStrawFive’. A new cultivar primarily characterized by its small, sweet tasting fruit, moderate resistance to high pH and high soil salt levels, is disclosed.

Description

Genus and species: Fragaria×ananassa.

Variety denomination: ‘DrisStrawFive’.

BACKGROUND OF THE NEW PLANT

The present invention relates to a new and distinct strawberry cultivar designated ‘DrisStrawFive’ and botanically known as Fragaria×ananassa. This new strawberry cultivar was discovered in Kent, England in August, 2002 and originated from a cross between the female parent ‘Driscoll Jubilee’ (U.S. Plant Pat. No. 15,435) and the male parent ‘Driscoll Camarillo’ (U.S. Plant Pat. No. 14,771). The original seedling of the new cultivar was asexually propagated at a nursery in Kent, England. ‘DrisStrawFive’ was subsequently asexually propagated by stolons and underwent further testing at a nursery in Monterey, Calif., for five years. The present invention has been found to retain its distinctive characteristics through successive asexual propagations by stolon.

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.

DESCRIPTION OF THE NEW CULTIVAR

The following description of ‘DrisStrawFive’ is based on observations taken from the 2002 to 2006 growing seasons in Monterey, 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. ‘DrisStrawFive’ has not been observed under all possible environmental conditions. Color terminology follows The Royal Horticultural Society Colour Chart, London (R.H.S.) (2001).
