Strawberry plant named ‘Nina’

- STRAWBERRY SCIENCES, LLC

This invention relates to a new and distinct variety of strawberry plant named ‘NIÑA’. This new strawberry plant named ‘NIÑA’ is primarily adapted to the growing conditions of West Central Florida, and is primarily characterized by its achenes typically set even with or just below the surface of the fruit, good fruit flavor with firm flesh, moderately creased fruit, early time of first flower and fruit, and large berry size.

Description

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

Variety denomination: ‘NIÑA’.

BACKGROUND

The present invention relates to a new and distinct strawberry variety named ‘NIÑA’. This new variety is a result of a controlled cross made in 2010 in an ongoing breeding program between strawberry variety designated ‘San Andreas’ (U.S. Pat. No. 19,975) as the seed (female) parent, and strawberry variety designated ‘BG-4.370’ (U.S. Pat. No. 17,864) 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, Fla. in the fall/winter of 2011-2012. 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 Hillsborough County, Fla. 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.

SUMMARY

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

    • 1. Achenes typically set even with or just below the surface of the fruit;
    • 2. Good fruit flavor with firm flesh;
    • 3. Moderately creased fruit;
    • 4. Early time of first flower and fruit;
    • 5. Large berry size

‘Florida Radiance’ (U.S. Pat. No. 20,363) has been a dominant strawberry variety in Hillsborough County, Fla. for more than ten years. The fruit of ‘SB_10_86-107’ are similar in flavor and firmness to ‘Florida Radiance’, but the fruits of ‘SB_10_86-107’ are more uniform and conical in shape during the early season. The achenes of ‘Florida Radiance’ are more sunken than those of ‘NIÑA’. In side-by-side comparisons from the 2017-2018 season (Nov. 11, 2017 to Feb. 23, 2018) and the 2018-2019 season (Nov. 15, 2018 to Feb. 27, 2019), ‘NIÑA’ compares with ‘Florida Radiance’ (U.S. Pat. No. 20,363) in the following combination of characteristics as described in Table 1.

TABLE 1 ‘Florida Radiance’ (U.S. Plant Pat. Characteristic ‘NIÑA’ No. 20,363) 2017-2018 November marketable yield (gm/plt) 29.9 29.7 Season marketable yield (grm/plt) 397.1 367.7 Season average berry size (gm) 31.7 25.5 Flavor Good Good 2018-2019 November marketable yield (gm/plt) 37.4 27.0 Season marketable yield (grm/plt) 471.3 495.1 Season average berry size (gm) 36.5 34.5 Flavor Good Good

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

‘NIÑA’ differs from its parents, ‘San Andreas’ and BG-4.370′ by the following combination of characteristics as described in Tables 2 and 3.

TABLE 2 ‘San Andreas’ (U.S. Plant Pat. Characteristic ‘NIÑA’ No. 19,975) Fruit: size Large Medium Fruit: marketable yield Ranges from medium to Medium high Fruit: flavor Good Fair Fruit: seed position Slightly below to even Sunken with surface

TABLE 3 Characteristic ‘NIÑA’ ‘BG-4.370’ Fruit: color Light to medium red Medium red Fruit: marketable yield Ranges from medium Medium to high Fruit: continuous yielding Continuous most years Gaps mid-season Susceptibility to Powdery Moderately susceptible Moderately Mildew resistant

 DETAILED BOTANICAL DESCRIPTION

The new variety ‘NIÑA’ has not been observed under all possible environmental conditions. The characteristics of the new variety ‘NIÑA’ 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 ‘NIÑA’, unless otherwise noted, are based on observations taken during the 2019-2020 growing season in Hillsborough County, Fla. These measurements and ratings were taken from plants of ‘NIÑA’ dug from a high-elevation nursery located in Siskiyou County, Calif. during mid-September 2019 and planted approximately four to five days later in Hillsborough County, Fla. The approximate age of the observed plants is five months. Yield observations including average weight and marketable yield, along with fruit quality characteristics including soluble solids, are averaged from five years of data collected from the 2015 through 2020 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 (2007).
