Strawberry plant named ‘DrisStrawNine’

Abstract

This invention relates to a new and distinct cultivar of strawberry plant named ‘DrisStrawNine’. A new cultivar primarily characterized by its small hollow center, early to medium flowering time, everbearing fruit, low number of achenes per berry, and moderate resistance to Strawberry Mottle Virus is disclosed.

Description

Genus and species: Fragaria×ananassa.

Variety denomination: ‘DrisStrawNine’.

BACKGROUND OF THE NEW PLANT

The present invention relates to a new and distinct strawberry cultivar designated ‘DrisStrawNine’ and botanically known as Fragaria×ananassa. This new strawberry cultivar was discovered in Summer, 2004 in Monterey, Calif. and originated from a cross between the female parent ‘94J283’, a proprietary strawberry plant (unpatented) and the male parent ‘112H25’, a proprietary strawberry plant (unpatented). The original seedling of the new cultivar was asexually propagated at a nursery in Monterey, Calif. ‘DrisStrawNine’ was subsequently asexually propagated 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.

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 photograph is of a plant about 7 months old.

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 upperside 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 ‘DrisStrawNine’ is based on observations taken from the 2004 to 2008 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. ‘DrisStrawNine’ has not been observed under all possible environmental conditions. Color terminology follows The Royal Horticultural Society Colour Chart, London (R.H.S.) (2001).
