Description

Latin name of the genus and species: The Latin name of the genus and species of the novel variety disclosed herein is Fragaria x ananassa.

Variety denomination: The inventive cultivar of Fragaria disclosed herein has been given the variety denomination ‘Bravura’.

BACKGROUND OF THE INVENTION

Parentage: ‘Bravura’ is the result of a controlled pollination breeding program carried out in April on 2008 in Ens, Netherlands. The new variety originated as a seedling from the crossing of Fragaria x ananassa ‘04-56-02’ (unpatented), the seed parent, with Fragaria x ananassa ‘03-61-04’ (unpatented) as the pollen parent. Seed from said cross was harvested, then germinated, and the resulting seedlings were grown to a mature size in order to evaluate for desirable commercial characteristics. In August of 2009, the inventor selected the new Fragaria for commercialization. This new and distinctive cultivar was given the name ‘Bravura’.

Asexual Reproduction: Asexual reproduction of ‘Bravura’, by way of rooting stolon cuttings, was first performed in September of 2009 in Ens, Netherlands. Through ten subsequent generations, the unique features of this cultivar have proven to be stable and true to type.

SUMMARY OF THE INVENTION

The cultivar ‘Bravura’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, day length, and light intensity, without, however, any variance in genotype. The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Bravura’. These characteristics in combination distinguish ‘Bravura’ as a new and distinct Fragaria cultivar:

    • 1. Fragaria ‘Bravura’ exhibits excellent resistance to Phytophthora cactorum root rotting disease; and
    • 2. Fragaria ‘Bravura’ exhibits very early, short-day fruiting; and
    • 3. Fragaria ‘Bravura’ exhibits large, firm fruit with a sweet flavor; and
    • 4. Fragaria ‘Bravura’ exhibits an orange-red general coloration of the mature fruit.

 BOTANICAL DESCRIPTION OF THE PLANT

The following is a detailed botanical description of a new and distinct variety of Fragaria known as ‘Bravura’, based upon observations of 3 month old greenhouse-grown plants in 250 cc nursery containers, produced in Ens, Netherlands. Plants were grown using conventional greenhouse production protocols for Fragaria plants which consisted of drip irrigation, as well as fertigation applications. Biological insect control measures were utilized in production. Plants were produced with full sun exposure and no photoperiodic treatments or artificial light was given to the plants. Observation data was recorded in April of 2018.

Those skilled in the art will appreciate that certain characteristics will vary with older or, conversely, with younger plants. ‘Bravura’ has not been observed under all possible environmental conditions. Where dimensions, sizes, colors and other characteristics are given, it is to be understood that such characteristics are approximations or averages set forth as accurately as practicable. The phenotype of the variety may differ from the descriptions set forth herein with variations in environmental, climatic and cultural conditions. Color notations are based on The Royal Horticultural Society Colour Chart, The Royal Horticultural Society, London, 2015 edition.

A botanical description of ‘Bravura’ and a comparison with the parent plants and the most similar commercial Fragaria cultivar known to the inventor, is provided below.
