Strawberry plant named ‘DrisStrawFortySeven’

Abstract

A new and distinct variety of strawberry plant named ‘DrisStrawFortySeven’ particularly characterized by having large, dark red, sweet fruit, a globose—semi-upright plant habit, and resistance to Tetranychus urticae, is disclosed.

Description

Genus and species: Fragaria×ananassa.

Variety denomination: ‘DrisStrawFortySeven’.

BACKGROUND OF THE NEW PLANT

The present invention relates to a new and distinct strawberry variety designated ‘DrisStrawFortySeven’ and botanically known as Fragaria×ananassa. This new strawberry variety was discovered in Ventura County, Calif. in January 2009 and originated from a cross between the proprietary female parent ‘41Q324’ (unpatented) and the proprietary male parent ‘DrisStrawThirtySeven’ (U.S. Plant Pat. No. 25,866). A single plant was selected and asexually propagated via tissue culture and vegetative cuttings in Shasta County, Calif. in 2009.

‘DrisStrawFortySeven’ underwent further testing in Ventura County, Calif. from 2010-2015. The present invention has been found to retain its distinctive characteristics through successive asexual propagations via stolons and tissue culture.

SUMMARY OF THE INVENTION

The following are the most outstanding and distinguishing characteristics of this new cultivar when grown under normal horticultural practices in Ventura County, Calif.

• • 1. Large, dark red, sweet fruit;
  • 2. Globose—semi-upright plant habit; and
  • 3. Resistant to Tetranychus urticae.

DESCRIPTION OF THE PHOTOGRAPHS

The accompanying color photographs show typical specimens of the new variety at various stages of development. The colors shown are as true as can be reasonably obtained by conventional photographic procedures. The photographs were taken from five-month-old plants.

DESCRIPTION OF THE NEW VARIETY

The following detailed descriptions set forth the distinctive characteristics of ‘DrisStrawFortySeven’. The data which define these characteristics is based on observations taken in Ventura County, Calif. from 2010 to 2015. 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. ‘DrisStrawFortySeven’ has not been observed under all possible environmental conditions. The botanical description of ‘DrisStrawFortySeven’ was taken from five-month-old plants. Color references are primarily to The R.H.S. Colour Chart of The Royal Horticultural Society of London (R.H.S.) (2007 edition). Descriptive terminology follows the Plant Identification Terminology, An Illustrated Glossary, 2^nd edition by James G. Harris and Melinda Woolf Harris, unless where otherwise defined.

COMPARISON WITH PARENTAL AND COMMERCIAL VARIETIES

When ‘DrisStrawFortySeven’ is compared to the female parent ‘41Q324’ (unpatented), ‘DrisStrawFortySeven’ is firmer with a more conic shape and better fruit appearance than ‘41Q324’.

When ‘DrisStrawFortySeven’ is compared to the male parent ‘DrisStrawThirtySeven’ (U.S. Plant Pat. No. 25,866), ‘DrisStrawFortySeven’ is less firm with lower yields and earlier production than ‘DrisStrawThirtySeven’.

‘DrisStrawFortySeven’ differs from the commercial variety ‘DrisStrawTwentySeven’ (U.S. Plant Pat. No. 23,400), in that ‘DrisStrawFortySeven’ has a globose—semi-upright plant habit and four crown per plant, whereas ‘DrisStrawTwentySeven’ has a flat globose plant habit and three crowns per plant. Additionally, ‘DrisStrawFortySeven’ has large, medium glossy fruit, whereas ‘DrisStrawTwentySeven’ has very large, strongly glossy fruit.
