Abstract
This invention relates to a new and distinct variety of strawberry plant named ‘BG-4315’. This new strawberry plant named ‘BG-4315’ is primarily adapted to the growing conditions of the central coast of California, and is primarily characterized by its weak interveinal blistering, acute terminal leaflet base, inner calyx is smaller than outer calyx, orange red to red fruit color, and medium to large fruit size.
Description

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


Variety denomination: ‘BG-4315’.


BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct strawberry variety named ‘BG-4315’. This new variety is a result of a controlled cross made in 2002 in an ongoing breeding program between strawberry variety designated ‘BG-633’ (patented, U.S. Plant Pat. No. 13,320) and strawberry variety designated ‘BG-1445’ (a non-patented selection). Due to the combining of the reciprocal seed lots, it is unknown as to which parent variety is the seed parent and which parent variety is the pollen 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 2004. After its selection, the new variety was asexually propagated by stolons in both San Joaquin County, Calif. and Siskiyou 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-4315’ is primarily adapted to the climate and growing conditions of the central coast of California. The nearby Pacific Ocean provides the needed humidity and moderate temperatures 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-4315’, which in combination distinguish this strawberry plant as a new and distinct variety:

    • 1. Weak interveinal blistering;
    • 2. Acute terminal leaflet base;
    • 3. Inner calyx is smaller than outer calyx;
    • 4. Orange red to red fruit color; and
    • 5. Medium to large fruit size.


The strawberry variety that is believed to be most closely related to the new variety ‘BG-4315’ is ‘BG-1975’ (patented, U.S. Plant Pat. No. 17,725). In side-by-side comparisons to the similar strawberry variety ‘BG-1975’, ‘BG-4315’ differs by the following combination of characteristics as described in Table 1.

BRIEF DESCRIPTIONS OF THE PHOTOGRAPHS

The accompanying color photographs illustrate the overall appearance of typical specimens of the new strawberry variety ‘BG-4315’, 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-4315’. The depicted plant and plant parts of the new strawberry variety ‘BG-4315’ are approximately six months old. The photographs were taken in Ventura County, Calif.:



FIG. 1 shows typical fruiting field characteristics of ‘BG-4315’, taken in the month of April 2011;



FIG. 2 shows a close-up view of the typical leaf structure of ‘BG-4315’, taken in the month of April 2011;



FIG. 3 shows typical mature and immature field fruit of ‘BG-4315’, taken in the month of April 2011; and



FIG. 4 shows typical internal and external mature fruit characteristics of ‘BG-4315’, taken in the month of April 2011.





DETAILED BOTANICAL DESCRIPTION

The new variety ‘BG-4315’ has not been observed under all possible environmental conditions. The characteristics of the new variety ‘BG-4315’ 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 1-9 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-4315’, unless otherwise noted, are based on observations taken during the 2011 growing season in Ventura County, Calif. These measurements and ratings were taken from plants of ‘BG-4315’ dug from a high-elevation nursery located in Siskiyou County, Calif. during early October 2010 and planted approximately four to five days later in Ventura County, Calif. The approximate age of the observed plants is six months. Yield observations and fruit quality characteristics are averaged from six years of data collected from the 2006 through 2011 growing seasons. Flower measurements and characteristics are from secondary flowers unless otherwise noted. Fruit characteristics and measurements are from secondary fruit unless otherwise noted.


Color terminology where noted follows The Royal Horticultural Society Colour Chart, London (2007).


The following tables 3-9 describe fruit, plant, stolon, foliage, fruiting truss, flower and pest disease characteristics of the new strawberry ‘BG-4315’ in comparison to the similar strawberry variety ‘BG-1975’.
