Description

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

Variety denomination: ‘SB_15_089-060’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct strawberry variety named ‘SB_15_089-060’. This new variety is a result of a controlled cross made in 2015 in an ongoing breeding program between the unreleased, unpatented strawberry breeding selection designated ‘SB_12_104-037’ as the seed (female) parent, and the unreleased, unpatented strawberry breeding selection designated ‘PS 6.1066’ 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 Hillsborough County, Florida in the fall/winter of 2016-2017. After its selection, the new variety was 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 in Hillsborough County, Florida. 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

‘SB_15_089-060’ is primarily adapted to the climate and growing conditions of West Central Florida. The subtropical climate of West Central Florida provides the day length and moderate temperatures needed to produce an early yielding, vigorous plant and maintain fruit quality during the fall and winter production months.

The following traits have been repeatedly observed and are determined to be unique characteristics of ‘SB_15_089-060’, which in combination distinguish this strawberry plant as a new and distinct variety:

    • 1. Achenes typically set even with or slightly below the surface of the fruit;
    • 2. Vigorous plant habit;
    • 3. Very high marketable yield;
    • 4. Early time of first flower and fruit; and
    • 5. Very large berry size.

‘Florida Brilliance’ (U.S. Plant Pat. No. PP30,564) is currently the dominant strawberry variety in Hillsborough County, Florida. The fruits of ‘SB_15_089-060’ are similar in skin integrity and berry shape to ‘Florida Brilliance’, but the fruit color of ‘Florida Brilliance’ is slightly lighter than the fruits of ‘SB_15_089-060’, and the seeds of ‘Florida Brilliance’ are slightly more sunken than those of ‘SB_15_089-060’. The plants of ‘SB_15_089-060’ are similar in vigor, openness of architecture, and uniformity to ‘Florida Brilliance’, but have slightly fewer runners per plant than ‘Florida Brilliance’. In side-by-side comparisons from the 2022-2023 season (Nov. 21, 2022 to Feb. 24, 2023) ‘SB_15_089-060’ compares with ‘Florida Brilliance’ (U.S. Plant Pat. No. PP30,564) in the following combination of characteristics as described in Table 1.

TABLE 1 ‘Florida Brilliance’ (U.S. Plant Pat. Characteristic ‘SB_15_089-060’ No. 30,564) Nov.-Dec. marketable 121 137 yield (gm/plt) Season marketable 184 303 yield (gm/plt) Nov.-Dec. average berry 22.4 17.1 size (gm) Season average berry 32.9 25.3 size (gm)

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

‘SB_15_089-060’ compares with its parents, ‘SB_12_104-037’ and ‘PS 6.1066’, by the following combination of characteristics as described in Tables 2 and 3.

 DETAILED BOTANICAL DESCRIPTION

The new variety ‘SB_15_089-060’ has not been observed under all possible environmental conditions. The characteristics of the new variety ‘SB_15_089-060’ 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 Table 1 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 ‘SB_15_089-060’, unless otherwise noted, are based on observations taken during the 2022-2023 growing season in Hillsborough County, Florida. These measurements and ratings were taken from plants of ‘SB_15_089-060’ dug from a high-elevation nursery located in Siskiyou County, California during mid-September 2022 and planted approximately four to five days later in Hillsborough County, Florida. The approximate age of the observed plants is four months. Yield observations including average weight and marketable yield, along with fruit quality characteristics including soluble solids, were measured during the 2022-2023 growing season. 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 (2015).
