1. A new and distinct variety of blueberry plant, substantially as illustrated and described, which is characterized principally as to novelty by a fruiting type on one-year-old shoots only, by an early vegetative bud burst timing, and by producing fruit considered medium in sweetness under the ecological conditions prevailing in Yanchep, Western Australia.

Description

BRIEF DESCRIPTION OF THE DRAWINGS

(1) The accompanying drawings are color photographs of the new blueberry plant ‘NS 16-15’ during the second 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 16-15’, 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 16-15’. 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, hereinafter, “R.H.S.”) and descriptions provided.

DETAILED BOTANICAL DESCRIPTION

Not A Commercial Warranty

(5) The following detailed description was prepared solely to comply with the provisions of 35 U.S.C. § 112, and does not constitute a commercial warranty (either expressed or implied) that the present variety will, in the future, display the botanical, horticultural, or other characteristics set forth herein. Therefore, this disclosure may not be relied upon to support any future legal claims including, but not limited to, breach of warranty of merchantability, or fitness for any particular purpose, or non-infringement, which is directed in whole, or in part, to the present new variety of plant.

(6) Referring more specifically to the botanical features of this new and distinct variety of blueberry plant, the following has been observed during the second year of growth under the ecological conditions prevailing at the breeder's property, which is located at Yanchep Springs in Yanchep, Western Australia. Plant: General. Vigor.—Considered medium to strong for the species. Growth habit.—Considered semi-upright. This is in comparison to the commercial variety ‘Bluetta’ (unpatented), which is considered to be semi-upright. Average size of plant.—0.84 meters in height by 0.50 meters in width. Internode length (space between nodes).—Considered short to medium, 16.4 millimeters (mm). Bark color.—RHS Brownish Orange Group 167A. Color, one year old shoots.—RHS Strong Yellow Green Group N144D. Fruiting Type.—On one-year-old shoots only, in like manner to commercial varieties ‘Darrow’ (unpatented) and ‘Patriot’ (unpatented). This is in contrast to the seed parent ‘EB 9-4’, the pollen parent ‘EB 8-46’, and the closest known variety ‘EB 8-42’, wherein the fruiting type is on one-year-old and current season shoots. Foliage: General. Average leaf length.—Considered medium for the species, 57.0 mm. Average leaf width.—Considered medium for the species, 25.9 mm. Color of leaf upper.—RHS Dark Yellowish Green Group 139A. Color of leaf underside.—RHS Pale Yellow Green Group N138C. Vein color of plant leaf.—RHS Light Yellow Green Group 145B. Venation pattern of leaf.—Pinnate reticulate. Leaf apex texture.—Glabrous. Leaf apex shape.—Acute. Leaf base shape.—Acute. Leaf shape.—Elliptic. Leaf margin.—Entire. Leaf arrangement of plant.—Alternate. Petiole length.—3.25 mm. Petiole diameter.—1.97 mm. Petiole color.—RHS Light Yellow Green 145C. Flowers: Number of flowers/inflorescence.—4-5 Length of inflorescence (excluding pedicel).—Considered long, 10 mm. Corolla shape.—Urceolate. Corolla tube surface texture.—Ridges are present on the corolla tube. Average corolla length.—Considered medium, 10.5 mm. Corolla diameter.—8.45 mm. Corolla aperture size.—5.47 mm. Corolla color.—RHS White Group NN155B. Pedicel color.—RHS Strong Yellow Green Group N144C. Pedicel length.—7.42 mm. Average calyx diameter.—Considered small, 3.42 mm. Average calyx basin depth.—Considered shallow, 1.0 mm. Attitude of sepals.—Erect. Type of sepals.—Straight. Reproductive organs: Size of pollen anthers.—4.34 mm. Color of pollen anthers.—RHS Brownish Orange Group 165B. Pistil length.—7.09 mm. Pistil color.—RHS Light Yellow Green Group 145B. Fruit: Color of unripe fruit.—RHS Light Yellow Green Group 145C. Color of fruit skin.—RHS Bluish Black Group 203C, also considered “dark blue” in like color to the commercial variety ‘Heerma’ (unpatented), after removal of bloom. Color of ripe fruit flesh.—RHS Light Yellow Green Group 145C. Color of seeds.—RHS Dark Reddish Orange Group 175C. Average fruit size.—19 mm in diameter and 13.05 mm in height. Average weight of fruit.—2.6 grams. Berry shape.—Considered oblate. Sweetness when ripe.—Considered medium for the species. This is in contrast to the seed parent ‘EB 9-4’ and the pollen parent ‘EB 8-46’, wherein the sweetness is considered high. This is also in contrast to the closest known variety ‘EB 8-42’, wherein the sweetness is considered medium to high. Firmness when ripe.—Considered firm for the species. Acidity when ripe.—Considered low for the species. Cluster density.—Considered dense for the species. Average fruit production.—3 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 mid- June, which is considered early for the species. This is comparable to the pollen parent ‘EB 8-46’, wherein the bud burst is also considered early. This is in contrast to the seed parent ‘EB 9-4’ and the closest known variety ‘EB 8-42’, wherein the bud burst is considered very early. Date of bloom time.—This variety is evergreen under the ecological conditions prevailing in Yanchep, Western Australia, but a bloom time occurs in mid-July, which is considered early on one-year old shoot in like manner to the commercial variety ‘Weymouth’ (unpatented). Duration of bloom time.—4 to 6 weeks. Beginning of fruit ripening.—considered early on one-year-old shoot in like manner to the commercial variety ‘Blueray’ (unpatented). First pick date.—The observed date of the first pick is approximately September under the ecological conditions prevailing in Yanchep, Western Australia.

Resistance to pests and disease.—No particular resistance noted. The variety has not been tested to detect any resistance.

(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.
