Strawberry plant named ‘BG-9.3128’


This invention relates to a new and distinct variety of strawberry plant named ‘BG-9.3128’. This new strawberry plant named ‘BG-9.3128’ is primarily adapted to the growing conditions of the central coast of California, and is primarily characterized by its orange red fruit color, large fruit size, very good fruit flavor, early fruit production, small plant size, and short fruiting trusses with flowers typically held even with to below the foliage.

Latin name: Fragaria ananassa.

Varietal denomination: ‘BG-9.3128’.


The present invention relates to a new and distinct strawberry variety named ‘BG-9.3128’. This new variety is a result of a controlled cross made in 2009 in an ongoing breeding program between strawberry variety designated ‘BG-4.352’ (U.S. Plant Pat. No. 26,921) as the seed (female) parent, and strawberry variety designated ‘BG-1975’ (U.S. Plant Pat. No. 17,725) as the pollen (male) parent. The variety is botanically known as Fragaria ananassa.

The seedling resulting from the aforementioned cross was selected from a controlled breeding plot in Ventura County, Calif. in the winter of 2011. After its selection, the new variety was asexually propagated by stolons in both Siskiyou County, Calif. and San Joaquin County, Calif. The new variety was extensively tested over the next several years in fruiting fields in Ventura County, Calif. This propagation has demonstrated that the combination of traits disclosed herein as characterizing the new variety are fixed and remain true-to-type through successive generations of asexual reproduction.


‘BG-9.3128’ is primarily adapted to the climate and growing conditions of the central coast of California. The nearby Pacific Ocean provides the humidity and moderate temperatures needed to produce a strong, vigorous plant and maintain fruit quality during the winter and spring production months.

The following traits have been repeatedly observed and are determined to be unique characteristics of ‘BG-9.3128’, which in combination distinguish this strawberry plant as a new and distinct variety:

    • 1. Orange red fruit color;
    • 2. Large fruit size;
    • 3. Very good fruit flavor;
    • 4. Early fruit production;
    • 5. Small plant size; and
    • 6. Short fruiting trusses with flowers typically held even with to below the foliage.

The strawberry variety that is believed to be most closely related to the new variety ‘BG-9.3128’ is ‘BG-959’ (U.S. Plant Pat. No. 17,864). In side-by-side comparisons to the similar strawberry variety ‘BG-959’, ‘BG-9.3128’ differs by the following combination of characteristics as described in Table 1.

TABLE 1 ‘BG-959’ (U.S. Plant Characteristic ‘BG-9.3128’ Pat. No. 17,864) Fruit: color Orange red Red Fruit: size Large Medium Fruit: flavor Very good Fair Fruit: firmness of flesh Firm Ranges from medium to firm Foliage: color Ranges from medium Ranges from medium to light green to dark green Foliage: gloss Absent Ranges from medium or very weak to strong Foliage: interveinal Absent Ranges from blistering or very weak medium to strong Stipule: anthocyanin Absent Strong intensity or very weak

For identification, a series of molecular markers have been determined for this new variety.

‘BG-9.3128’ differs from its parents, ‘BG-4.352’ and ‘BG-1975’ by the following combination of characteristics as described in Tables 2 and 3.

The accompanying color photographs illustrate the overall appearance of typical specimens of the new strawberry variety ‘BG-9.3128’ at various stages of development, as true as it is reasonably possible with color reproductions of this type. Color in the photographs may differ slightly from the color value cited in the botanical descriptions which accurately describe the color of ‘BG-9.3128’. The depicted plant and plant parts of the new strawberry variety ‘BG-9.3128’ are approximately six months old. The photographs were taken in Ventura County, Calif.

The new variety ‘BG-9.3128’ has not been observed under all possible environmental conditions. The characteristics of the new variety ‘BG-9.3128’ may vary in detail, depending upon variations in environmental factors, including weather (temperature, humidity and light intensity), day length, soil type and location. In addition, the characteristics of any parental variety or comparison variety included in Tables 1, 2 and 3 of the present invention may vary in detail, depending upon variations in environmental factors, including weather (temperature, humidity and light intensity), day length, soil type and location.

The aforementioned photographs, together with the following description of the new variety ‘BG-9.3128’, unless otherwise noted, are based on observations taken during the 2018 growing season in Ventura County, Calif. These measurements and ratings were taken from plants of ‘BG-9.3128’ dug from a high-elevation nursery located in Siskiyou County, Calif. during early October 2017 and planted approximately four to five days later in Ventura County, Calif. The approximate age of the observed plants is six months. Yield observations including average weight and marketable yield, along with fruit quality characteristics including soluble solids, are averaged from four years of data collected from the 2015 through 2018 growing seasons. Flower measurements and characteristics are from secondary flowers unless otherwise noted. Fruit characteristics and measurements are from secondary fruit, unless otherwise noted.

Where noted, color terminology follows The Royal Horticultural Society Colour Chart, London (2007).
