Abstract
This invention relates to a new and distinct variety of strawberry plant named ‘PS-5096’. This new strawberry plant named ‘PS-5096’ is primarily adapted to the growing conditions of the central coast of California, and is characterized by medium to small sized fruit which are orange-red to red in color; medium to small calyx diameter; conical, glossy fruit with the calyx which tends to be slightly reflexed; medium green foliage, which is slightly concave to slightly convex in shape with medium interveinal blistering and gloss; and position of fruiting truss tends to be more level with to above the plant with weak pubescence.
Description

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


Variety denomination: ‘PS-5096’.


BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct strawberry variety designated as ‘PS-5096’. This new variety is a result of a controlled cross made by the inventors Stephen M. Ackerman, Steven D. Nelson, and Michael D. Nelson, in 1997 between strawberry variety ‘PS-592’ (patented, U.S. Plant Pat. No. 9,903) and strawberry variety designated ‘PS-1150’ (patented, U.S. Plant Pat. No. 10,780). 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 asexually propagated by stolons in a nursery located in Siskiyou County, California, and was subsequently selected by the inventors from a controlled breeding plot in Salinas, Calif., in 1999. After its selection, the new variety was further asexually propagated by stolons in both Siskiyou County, California and San Joaquin County, California. The new variety was extensively tested over the next several years in fruiting fields of Salinas, 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

‘PS-5096’ is primarily adapted to the climate and growing conditions of the central 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 April through November. The nearby Pacific Ocean provides the needed humidity and moderate temperatures to maintain fruit quality during the spring and summer production months.


The following traits have been repeatedly observed and are determined to be unique characteristics of ‘PS-5096’, which in combination distinguish this strawberry plant as a new and distinct variety:

    • 1. Medium to small sized fruit;
    • 2. Orange-red to red fruit color;
    • 3. Medium to small calyx diameter;
    • 4. Conical, glossy fruit with the calyx which tends to be slightly reflexed;
    • 5. Medium green foliage; slightly concave to slightly convex in shape with medium interveinal blistering and gloss; and
    • 6. Position of fruiting truss tends to be more level with to above the plant with weak pubescence.


The strawberry varieties that are believed to be most closely related to the new strawberry variety ‘PS-5096’ are the parental cultivars, strawberry variety ‘PS-592’ (patented, U.S. Plant Pat. No. 9,903) and strawberry variety ‘PS-1150’ (patented, U.S. Plant Pat. No. 10,780).


In side-by-side comparisons to the similar strawberry varieties ‘PS-592’ and ‘PS-1150’, the new strawberry variety ‘PS-5096’ 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 ‘PS-5096’, 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 description which accurately describe the color of ‘PS-5096’. The depicted plant and plant parts of the new strawberry variety ‘PS-5096’ were taken in Salinas, Calif., and are approximately 8 to 9 months old.

DETAILED BOTANICAL DESCRIPTION

‘PS-5096’ 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 variety ‘PS-5096’, unless otherwise noted, is based on observations taken during the 2006 growing season in Salinas, Calif. These measurements and ratings were taken from plants of ‘PS-5096’ dug from a high-elevation nursery located in Siskiyou County, California during the middle of October 2005 and planted approximately 3 weeks later in Salinas, Calif. The approximate age of the observed plants is 7 to 10 months. Yield observations and fruit quality characteristics are averaged from four years of data collected from the 2003 through 2006 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 Munsell Book of Colors, Munsell Color, Baltimore, Md. (1976).


The following Tables 2-8 describe fruit, plant, stolon, foliage, fruiting truss, flower and pest/disease characteristics of the new strawberry ‘PS-5096’ in comparison to the similar strawberry varieties ‘PS-592’ and ‘PS-1150’.
