Description

Description

Latin name: ‘Vaccinium Hybrid’.

Varietal denomination: ‘EB 8-46’.

RELATED APPLICATION DATE

The present application claims priority to Australia Plant Breeders Rights Application, Serial No. 2012/260 and which was filed on Nov. 29, 2012.

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 8-46’, hereinafter.

ORIGIN AND ASEXUAL REPRODUCTION OF THE NEW VARIETY

The present variety of blueberry plant resulted from an ongoing development program of plant breeding. The purpose of this program is to improve the commercial quality of various plant varieties by creating and releasing promising selections of plants including blueberries. To this end, I have made both controlled and hybrid cross-pollinations each year in order to produce resulting plant populations from which improved progenies are evaluated and selected.

The blueberry plant ‘EB 8-46’ was derived from a controlled cross-pollination employing the blueberry plant ‘BB-5’ [unpatented], and the pollen parent was ‘SB-1’ [also unpatented] during the 2005 growing season and which took place at Yanchep Springs, Yanchep, Western Australia. The seed parent ‘BB-5’ is characterized by an semi-spreading growth habit, an early season of flowering, and which further produces medium-sized fruit. The pollen parent ‘SB-1’ on the other hand, is characterized by a spreading growth habit, an early season of flowering, and which produces relatively large sized fruit. Seed from the seed parent, and which was derived following the aforementioned cross-pollination, produced about 500 plants. These plants were then grown, and the first fruit was evaluated during the 2007 growing season. Further, an additional assessment of these same plants took place in 2008. The new variety, ‘EB 8-46’ was then selected at that time for further asexual reproduction and evaluation. The present variety was asexually reproduced by cuttings, and the plants produced from this first asexual propagation were evaluated during the 2009 through 2013 growing seasons. The asexually reproduced plants were true to the original plant, and it was concluded at that time that ‘EB 8-46’ was a new, novel and distinct variety of blueberry plant.

In relative comparison to the closest known variety, that being the ‘Sharpeblue’ blueberry plant [unpatented], the present variety produces early maturing, very large fruit. The new variety of blueberry plant further has an intermediate growth habit, and additionally produces oblate shaped fruit. In contrast, the ‘Sharpeblue’ blueberry plant produces fruit which are mature for harvesting and shipment from a date which is considered early to approximately middle of the growing season. Moreover, the ‘Sharpeblue’ blueberry plant produces fruit which have an average to medium size, and also has an intermediate growth habit. It should be noted that the new variety is distinguishable from its parents, and that of the ‘Sharpeblue’ blueberry plant by producing extra large sized fruit, having a dry, small, picking scar, very good fruit flavor and early flowering and fruit production dates.
