RELATED APPLICATION DATA

The present application claims priority to Australian Plant Breeders Rights application Serial No. 2014/243, and which was filed one Oct. 16, 2014, and which was further accepted on Dec. 23, 2014.

BACKGROUND OF THE NEW VARIETY

The present invention relates to a new, novel and distinct variety of blueberry plant ‘Vaccinium hybrid’ and which has been denominated varietally as ‘EB 9-2’.

ORIGIN

The present variety of blueberry plant resulted from an ongoing development program which I have conducted to identify such plants. The purpose of this program is to improve the commercial quality of blueberry plants, and other species. To this end, I have made controlled hybrid cross-pollinations in order to produce plant populations from which improved progeny are evaluated, and thereafter selected.

The blueberry plant ‘EB 9-2’ was originated by me and selected from a population of new plants growing at my farm which is located near Yanchep Springs, in Yanchep, Western Australia. The new variety of blueberry plant was derived from a controlled cross-pollination of the seed parent, blueberry plant ‘BB-1’ [unpatented], and a pollen parent, blueberry plant ‘03-2’ [unpatented], during the 2006 growing season. The seed parent, blueberry parent ‘BB-1’ is principally characterized by a semi-upright bush-type growing habit; a mid-season flowering date; and which further produces medium to large, firm, fruit. Still further, the pollen parent, blueberry plant ‘03-2’ is principally characterized by a semi-upright growth habit; a mid-season flowering date; and which further produces large fruit. Following this cross-pollination, seed from the seed parent ‘BB-1’ produced approximately 500 plants. The first fruiting of these new plants was first observed in 2008. A complete assessment of the fruit, and growth habits of these new plants were evaluated in 2009. After this full assessment, the newly discovered variety ‘EB 9-2’ was selected for further asexual propagation and study. Further, asexual reproduction of the newly discovered variety ‘EB 9-2’ occurred during the 2010 through 2014 growing seasons. The subsequently conducted evaluations of the newly asexually propagated plants, and the fruit produced thereby, has lead the inventor to conclude that the newly discovered blueberry plant variety, ‘EB 9-2’, is a distinct, and new variety in view of its displayed upright, to semi-upright bush-type growth habit; large to very large and oblate shaped fruit; and which further has an excellent flavor; and a very early flowering, and fruit maturity dates in relative comparison to the closest known varieties. The asexual reproduction of this new and novel Blueberry plant named ‘EB 9-2’ occurred at Yanchep Springs, Western Australia.

In comparison to the seed parent ‘BB-1’, the present, newly discovery plant is clearly distinguishable therefrom based upon its flowering date. For example, the seed parent flowering date is considered mid-season under the ecological conditions prevailing in Yanchep Springs, Western Australia. On the other hand, the present, new variety has a date of flowering which is considered very early in the season. This is similarly the case with the pollen parent, blueberry plant ‘03-2’, and which also has a mid-season flowering date. Still further, the new variety of blueberry plant is distinguishable from its seed parent in view of the fruit size produced by the new plant. In this regard, the new variety of blueberry plant produces large to very large fruit in relative comparison to the seed parent, and which produces only medium to large fruit; and the pollen parent which produces large sized blueberries.

The present, new and novel variety of blueberry plant is distinguishable from the most closely known variety, that being blueberry plant ‘EB 8-1’ which is further identified as U.S. Plant Pat. No. 25,859, and which was filed on Jun. 12, 2013 in view of the differing plant vigor; displayed growth habit; fruit bloom intensity; fruit firmness; fruit acidity; fruit weight, and other plant characteristics which will be discussed in the specification which follows. Still further, the new variety is clearly distinguishable from the common commercial blueberry plant variety ‘Ridley 1111’ which is further identified as U.S. Plant Pat. No. 23,572 and which was filed on Jan. 18, 2011. The blueberry plant variety ‘Ridley 1111’ produces medium to large sized fruit in comparison to the new variety of blueberry parent, and which produces large to very large fruit. It should be understood that the asexual propagation of the new, present variety of blueberry plant was accomplished by means of cuttings. The observations of the new and novel plants has taken place over a number of years and the inventor has repeatedly confirmed that the novel characteristics of the present, new variety of blueberry plant are stable across multiple generations.

BRIEF DESCRIPTION OF THE DRAWING

The accompanying drawing which is provided is a color photograph of the new blueberry plant ‘EB 9-2’, at an age of two (2) years, and which is juxtaposed relative to an image of the closest known variety, that being ‘EB 8-1’ (U.S. Plant Pat. No. 25,859). The photograph illustrates the new variety, and shows a portion of a vegetative stem which displays the growth habit of the leaves; one leaf is further illustrated showing the dorsal coloration thereof; and several fruit are depicted showing both the dorsal and ventral coloration, and the morphology of same. The photograph additionally shows a vegetative stem showing typical leaves and the fruit produced by the closest known variety, that being blueberry plant ‘EB 8-1’ (U.S. Plant Pat. No. 25,859).

The color in this photograph is as nearly true as is possible in a color representation of this type. Due to chemical development, processing, and printing, the leaves and fruit depicted in this photograph may or may not be accurate when compared to the actual specimens. For this reason, future color references should be made to the color plates, and descriptions provided hereinafter. Common color names are also employed in the specification which follows.
