Abstract

This invention relates to a new and distinct short-day variety of strawberry plant named ‘BG-1975’. This new strawberry variety ‘BG-1975’ is primarily adapted to the growing conditions of the southern coast of California, and is primarily characterized by foliage medium to small in size and light to medium green in color, production is early, beginning as early as late December, producing upwards of 50% to 60% of it production by the end of March, produced fruit is attractive and of excellent quality, produced fruit is orange red to red in color, medium to large in size, very firm, conical to cylindrical in shape with a smooth surface lacking creases and ridges, and seeds may be slightly sunken below the surface.

Description

Latin name of the genus and species of the plant claimed: Fragaria ananassa.
Variety denomination: ‘BG-1975’.
BACKGROUND OF THE INVENTION
The present invention relates to a new and distinct short-day strawberry variety designated as ‘BG-1975’. This new variety is a result of a controlled cross made by the Inventors, Steven D. Nelson, Michael D. Nelson and Lee W. Stoeckle, in 1999 between strawberry variety designated ‘BG-269’ (patented, U.S. Plant Pat. No. 12,628) and strawberry variety designated ‘BG-633’ (patented, U.S. Plant Pat. No. 13,320). The variety is botanically known as Fragaria ananassa.
The seedling resulting from the aforementioned cross was asexually propagated by stolons in a nursery located in Siskiyou County, Calif., and was subsequently selected by the Inventors from a controlled breeding plot near Oxnard, Calif., in 2001. After its selection, the new variety was further 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 near Oxnard, 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-1975’ is primarily adapted to the climate and growing conditions of the southern coast of California. This region provides the necessary winter temperatures required for it to produce a strong vigorous plant and to remain in fruit production from January through June. The nearby Pacific Ocean provides the needed humidity and moderate temperatures to 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-1975’, which in combination distinguish this strawberry plant as a new and distinct variety:
    • 1. foliage medium to small in size and light to medium green in color;
    • 2. production is early, beginning as early as late December, producing upwards of 50% to 60% of it production by the end of March;
    • 3. produced fruit is attractive and of excellent quality;
    • 4. produced fruit is orange red to red in color, medium to large in size, very firm, conical to cylindrical in shape with a smooth surface lacking creases; and
    • 5. ridges, and seeds may be slightly sunken below the surface.
The strawberry varieties that are believed to be most closely related to the new strawberry variety ‘BG-1975’ are the parental strawberry variety ‘BG-269’ (patented, U.S. Plant Pat. No. 12,628) and the strawberry variety ‘BG-625’ (patented, U.S. Plant Pat. No. 13,255).
In comparison to the similar strawberry varieties ‘BG-269’ and ‘BG-625’, ‘BG-1975’ differs by the following combination of characteristics as described in Table 1:

BRIEF DESCRIPTIONS OF THE DRAWINGS
The accompanying color photographs illustrate the overall appearance of typical specimens of the new strawberry variety ‘BG-1975’ at various stages of development as true as is reasonably possible with color reproductions of this type. Color in the photographs may differ slightly from the color value cited in the botanical description which accurately describe the color of ‘BG-1975’. The depicted plant and plant parts of the new strawberry variety ‘BG-1975’ were taken in Oxnard, Calif., and are approximately 5 to 6 months old.

 DETAILED BOTANICAL DESCRIPTION
‘BG-1975’ has not been observed under all possible environmental conditions. The characteristics of the new variety 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 strawberry variety ‘BG-1975’, unless otherwise noted, is based on observations taken during the 2005 growing season in Oxnard, Calif. These measurements and ratings were taken from plants of ‘BG-1975’ dug from a high-elevation nursery located in Siskiyou County, Calif., during the first week of October 2004 and planted 4 days later in Oxnard, Calif. The approximate age of the observed plants are 5 to 6 months. Yield observations and fruity quality characteristics are averaged from three years of data collected from the 2003 through the 2005 growing seasons.
Color terminology follows the Munsell Book of Colors, Munsell Color, Baltimore, Md. (1976).
  • Fruit characteristics: Tables 2, 3 and 4 describe the fruit, fruit production and fruit quality characteristics of ‘BG-1975’. Fruit characteristics are taken from secondary fruit on a first year planting.
