Genus and species: Fragaria×ananassa.

Variety denomination: ‘DrisStrawFifty’.


The present invention relates to a new and distinct strawberry variety designated ‘DrisStrawFifty’ and botanically known as Fragaria×ananassa. This new strawberry variety was discovered in Huelva, Spain in March 2010, and originated from a cross between the proprietary female parent ‘DrisStrawSixteen’ (U.S. Plant Pat. No. 22,247) and the proprietary male parent ‘RES 070-001’ (unpatented). A single plant was selected and asexually propagated via tissue culture and vegetative cuttings in Huelva, Spain in 2010.

‘DrisStrawFifty’ underwent further testing in Doñana, Huelva, Spain from 2011-2015. The present invention has been found to retain its distinctive characteristics through successive asexual propagations via stolons and tissue culture.


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

    • 1. Medium-sized, dark orange-red fruit;
    • 2. Globose-semi-upright plant habit; and
    • 3. Mid-season harvest maturity.


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 six-month-old plants.

FIG. 1 shows upper and lower surfaces of the leaves of the plant with three leaflets.

FIG. 2 shows both upper and lower surfaces of the flowers.

FIG. 3 shows the whole fruit.

FIG. 4 shows the fruit in longitudinal cross-section.


The following detailed descriptions set forth the distinctive characteristics of ‘DrisStrawFifty’. The data which define these characteristics is based on observations taken in Huelva, Spain from 2011 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. ‘DrisStrawFifty’ has not been observed under all possible environmental conditions. The botanical description of ‘DrisStrawFifty’ was taken from six-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, 2nd edition by James G. Harris and Melinda Woolf Harris, unless where otherwise defined.

When ‘DrisStrawFifty’ is compared to the female parent ‘DrisStrawSixteen’ (U.S. Plant Pat. No. 22,247), ‘DrisStrawFifty’ produces globose-semi-upright plants with medium vigor, while the plants of ‘DrisStrawSixteen’ have a globose habit with strong vigor. Additionally, plants of ‘DrisStrawFifty’ produce a medium number of stolons with strong anthocyanin coloration, while ‘DrisStrawSixteen’ plants produce few stolons, with little or no anthocyanin coloration.

When ‘DrisStrawFifty’ is compared to the male parent ‘RES 070-001’ (unpatented), ‘DrisStrawFifty’ has slightly smaller fruit than ‘RES 070-001’.

‘DrisStrawFifty’ differs from the commercial variety ‘DrisStrawEight’ (U.S. Plant Pat. No. 20,735), in that ‘DrisStrawFifty’ has medium-sized fruit that is dark orange-red in color with weak glossiness, whereas ‘DrisStrawEight’ has large fruit that is medium red in color with medium glossiness. Additionally, plants of ‘DrisStrawFifty’ have a globose-semi-upright habit, whereas plants of ‘DrisStrawEight’ have a globose habit.
