Abstract

This invention relates to a new and distinct variety of strawberry plant named ‘BG-11.3209’. This new strawberry plant named ‘BG-11.3209’ is primarily adapted to the growing conditions of the central coast of California, and is primarily characterized by its red fruit color, large fruit size, and conical fruit shape; very good fruit flavor, with seeds typically held level with to above the surface; firm fruit, with calyx typically raised and sepal attitude generally outward to upward; medium plant size, upright in habit, with medium density and vigor; medium yellow green foliage color, and medium foliage size; and fruiting trusses typically visible above the foliage, with medium to weak pubescence and medium to strong anthocyanins.

Description

Latin name of the genus and species of the plant claimed: Fragaria ananassa.

Variety denomination: ‘BG-11.3209’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct strawberry variety named ‘BG-11.3209’. This new variety is a result of a controlled cross made in 2011 in an ongoing breeding program between strawberry variety designated ‘BG-99.1975’ (U.S. Plant Pat. No. 17,725) as the seed (female) parent, and strawberry variety designated ‘BG-4.370’ (U.S. Plant Pat. No. 27,441) 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 spring of 2013. 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.

BRIEF SUMMARY OF THE INVENTION

‘BG-11.3209’ 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-11.3209’, which in combination distinguish this strawberry plant as a new and distinct variety:

- 1. Fruit is red in color, large in size, and conical in shape;
- 2. Fruit has very good flavor, with seeds typically held level with to above the surface;
- 3. Fruit is firm, with calyx typically raised and sepal attitude generally outward to upward;
- 4. Plant is medium in size, upright in habit, with medium density and vigor;
- 5. Foliage is medium yellow green in color, and medium in size; and
- 6. Fruiting trusses are typically visible above the foliage, with medium to weak pubescence and medium to strong anthocyanins.

The strawberry variety that is believed to be most closely related to the new variety ‘BG-11.3209’ is ‘BG-9.3142’ (U.S. Plant Pat. No. 29,794). In side-by-side comparisons to the similar strawberry variety ‘BG-9.3142’, ‘BG-11.3209’ differs by the following combination of characteristics as described in Table 1.

DETAILED BOTANICAL DESCRIPTION

The new variety ‘BG-11.3209’ has not been observed under all possible environmental conditions. The characteristics of the new variety ‘BG-11.3209’ 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-11.3209’, unless otherwise noted, are based on observations taken during the 2022 growing season in Ventura County, Calif. These measurements and ratings were taken from plants of ‘BG-11.3209’ dug from a high-elevation nursery located in Siskiyou County, Calif. during early October 2021 and planted approximately four to five days later in Ventura County, Calif. The approximate age of the observed plants is five to six months. Yield observations including average weight and marketable yield, along with fruit quality characteristics including soluble solids, are averaged from seven years of data collected from the 2015 through 2021 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, Sixth Edition (2015).
