Description

BRIEF DESCRIPTION OF THE DRAWINGS

(1) The accompanying drawings are color photographs of the new blueberry plant ‘NS 15-15’ during the third year of growth under the ecological conditions prevailing at the breeder's property, which is located at Yanchep Springs in Yanchep, Western Australia.

(2) FIG. 1 is a color photograph, which shows fruit, blooms, leaves, and a portion of a vegetative stem of the new blueberry plant ‘NS 15-15’, the fruit being sufficiently mature for harvesting and shipment. This photograph also depicts the fruit size and the color of the ripe fruit, two leaves showing the sizes and the upper and under side colorations thereof, two blooms at different stages of maturation, and additional leaves on the stem at different stages of maturation.

(3) FIG. 2 is a color photograph, which shows the new blueberry plant ‘NS 15-15.’ This photograph depicts a mature bush with ripe and unripe fruits, the fruit size, and the upright growth habit of the bush. The ripe fruit is sufficiently mature for harvesting and shipment.

(4) The colors in these photographs are as nearly true as is reasonably possible in a color representation of this type. Due to variations in color printers and/or chemical development, processing and printing, the colors of the plant parts depicted in these photographs may, or may not, be accurate when compared to the actual specimen. For this reason, color references are made to the color plates (Royal Horticultural Society Colour Chart, Sixth Edition (2015), hereinafter, “R.H.S.”) and descriptions provided.

Internode length (space between nodes).—Considered medium, 22.41 millimeters (mm). Bark color.—RHS Light Reddish Brown Group 177C. Color, one year old shoots.—RHS Greyish Red Group 182B. Fruiting type.—On one-year-old shoots and current season's shoots. Foliage: General. Average leaf length.—Considered medium to long for the species, 60.89 mm. Average leaf width.—Considered medium to broad for the species, 30.48 mm. Color of leaf upper.—RHS Greyish Olive Green Group NN137A. Color of leaf underside.—RHS Greyish Yellow Green Group 191A.

Leaf shape.—Elliptic. Leaf margin.—Entire. Leaf arrangement of plant.—Alternate. Petiole length.—4.37 mm. Petiole diameter.—2.34 mm. Petiole color.—RHS Light Yellow Green 145C. Flowers: Number of flowers/inflorescence.—4. Length of inflorescence (excluding pedicel).—Considered long, 10.52 mm. Infructescence density.—Considered medium. Corolla shape.—Urceolate. Corolla tube surface texture.—Ridges are present on the corolla tube. Average corolla length.—10.52 mm. Corolla diameter.—9.56 mm. Corolla aperture size.—4.15 mm. Corolla color.—RHS White Group NN155B. Conspicuousness of ridges on corolla tube.—Considered medium. Pedicel color.—RHS Moderate Yellow Green Group 146B. Pedicel length.—4.65 mm. Average calyx diameter.—Considered small, 2.97 mm. Average calyx basin depth.—Considered medium, 2.36 mm. Attitude of sepals.—Erect. Type of sepals.—Reflexed. Color of receptacle.—RHS Moderate Yellow Green Group 146B. Reproductive organs: Size of pollen anthers.—7.36 mm. Color of pollen anthers.—RHS Brownish Orange Group N167A. Pistil length.—9.35 mm. Pistil color.—RHS Light Yellow Green Group 145B. Fruit: Color of unripe fruit.—RHS Strong Yellow Green Group 144A. Color of fruit skin.—RHS Bluish Black Group 203C at time of bloom removal. Color of ripe fruit flesh.—RHS Light Yellow Green Group 145B. Color of seeds.—RHS Brownish Orange Group N167A. Average fruit size.—Very large, 20-22 mm in diameter and 13.83 mm in height. This is in contrast to the seed parent ‘EB 9-4’, the pollen parent ‘EB 8-50’, and the closest known variety ‘NS 16-18’, wherein the fruit size is considered large to very large. Average weight of fruit.—2.5 grams. Fruit height/width ratio.—Considered medium. Berry shape.—Considered oblate. Sweetness when ripe.—Considered medium to high for the species. Firmness when ripe.—Considered firm for the species. This is comparable to the seed parent ‘EB 9-4’, wherein the fruit firmness is also considered firm. This is in contrast to the pollen parent ‘EB 8-50’ and the closest known variety ‘NS 16-18’, wherein the fruit firmness is considered firm to very firm. Acidity when ripe.—Considered low to medium for the species. This is comparable to the seed parent ‘EB 9-4’, wherein the fruit acidity is also considered low to medium. This is in contrast to the pollen parent ‘EB 8-50’, wherein the fruit acidity is considered low. This is also in contrast to the closest known variety ‘NS 16-18’, wherein the fruit acidity is considered medium to high. Cluster density.—Considered medium for the species. Average fruit production.—3.5 kilograms on a two-year-old bush. Storability of fruit.—Considered excellent for the species. Market use of fruit.—1st grade fresh market fruit. Date of bud burst.—This variety is evergreen under the ecological conditions prevailing in Yanchep, Western Australia, but a bud break occurs in August, which is considered medium in timing.

Duration of bloom time and bloom intensity.—4-6 weeks; bloom intensity is considered strong. Beginning of fruit ripening.—Considered very early on one-year-old shoot and very early on current year's shoots. First pick date.—The observed date of the first pick is approximately August under the ecological conditions prevailing in Yanchep, Western Australia. Last pick date.—The observed date of the last pick is approximately October under the ecological conditions prevailing in Yanchep, Western Australia. Pollination requirements.—Self-fertile.

(7) Although the new variety of blueberry plant possesses the described characteristics when grown under the ecological conditions prevailing in Yanchep, Western Australia, it should be understood that variations are to be expected in the usual magnitude and characteristics incident to changes in growing conditions, fertilization, pruning, pest control, frost, climatic variables, and horticultural management.
