USPP24395P3 - Strawberry plant named ‘DrisStrawThirtyFour’ - Google Patents

Abstract

A new and distinct variety of strawberry plant named ‘DrisStrawThirtyFour’ particularly characterized by a very early harvest maturity, medium sized fruit, and very glossy fruit with sweet flavor, is disclosed.

Description

Genus and species: Fragaria×ananassa.

Variety denomination: ‘DrisStrawThirtyFour’.

BACKGROUND OF THE NEW PLANT

The present invention relates to a new and distinct strawberry variety designated ‘DrisStrawThirtyFour’ and botanically known as Fragaria×ananassa. This new strawberry variety was discovered in Avitorejo, Spain in March 2010 and originated from a cross between the proprietary female parent ‘RES 050-002’ (unpatented) and the proprietary male parent ‘91P298’ (unpatented). A single plant was selected for asexual propagation via tissue culture and vegetative cuttings in Avitorejo, Spain.

‘DrisStrawThirtyFour’ underwent further testing in Avitorejo, Spain for three years (2010-2012). The present invention has been found to retain its distinctive characteristics through successive asexual propagations via stolons and tissue culture.

Plant Breeder's Rights for this variety have not been applied for. ‘DrisStrawThirtyFour’ has not been made publicly available or sold more than one year prior to the filing date of this application.

SUMMARY OF THE INVENTION

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

• • 1. Very early harvest maturity;
  • 2. Medium sized fruit; and
  • 3. Very glossy fruit with sweet flavor.

DESCRIPTION OF THE PHOTOGRAPH

The accompanying color photograph shows 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 photograph is of whole plants approximately five to seven month-old and shows leaves, flowers, and fruit at various stages of development.

DESCRIPTION OF THE NEW VARIETY

The following detailed descriptions set forth the distinctive characteristics of ‘DrisStrawThirtyFour’. The data which define these characteristics is based on observations taken in Avitorejo, Spain from 2010 to 2012. 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. ‘DrisStrawThirtyFour’ has not been observed under all possible environmental conditions. The botanical description of ‘DrisStrawThirtyFour’ was taken from five to seven 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.
