Abstract

A new and distinct variety of blueberry plant, which is denominated varietally as ‘EB 8-21’ and which produces fruit which are mature for harvesting and shipment early in the season, and which is very large in size and which further displays a growth pattern which is upright when grown under the ecological conditions prevailing in Yanchep Springs, Western Australia.

Description

Latin name: ‘Vaccinium Hybrid’.

Varietal denomination: ‘EB 8-21’.

RELATED APPLICATION DATA

The present application claims priority to Australian Plan Breeders Rights Application Serial No. 2012/257 and which was filed on Nov. 28, 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 8-21’, 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 experimental plant populations from which improved progenies are evaluated and selected.

The blueberry plant ‘EB 8-21’ was originated by me and selected from a population of new plants growing on my farm, and which is located near Yanchep Springs, Western Australia. The new plant was derived from a controlled pollination, which was conducted using the seed parent ‘SB-1’, and the pollen parent ‘03-6’ during the 2005 growing season, on my farm which is located in Yanchep Springs, Yanchep Western Australia. The seed parent ‘SB-1’, and the pollen parent ‘03-6’ are both unpatented. The seed parent is principally characterized as to novelty by a semi-spreading growth habit; an early season of flowering; and which further produces fruit having a medium size for the species. On the other hand, the pollen parent is characterized by a spreading growth habit; an early season of flowering; and which further produces large fruit. Seed derived from the seed parent (‘SB-1’) [unpatented], produced approximately 500 plants. The first fruit from this first cross-pollination was studied during the 2007 growing season.

A subsequent assessment took place in 2008, and the new variety ‘EB 8-21’ showed particularly desirable character traits. Further commercial testing including vegetative propagation from cuttings taken from ‘EB 8-21’ occurred during the 2009 through 2012 growing seasons. The resulting progeny appeared true to the original plant. Subsequent evaluations has led the inventor to conclude that the new variety is novel and distinct. The present variety is characterized as to novelty by producing extra large sized fruit, and which further has a small, dry picking scar, very good fruit flavor, and an early flowering and fruit production dates.

The closest known variety to the new variety ‘EB 8-21’ is the “Sharpeblue” blueberry plant (unpatented), and which produces fruit which are mature for harvesting and shipment early to the middle of the season, and which further has a fruit size which is average as compared to other blueberry plants. Still further, the “Sharpeblue” blueberry plant has an intermediate growth habit and a fruit shape which is considered to be oblate. The new plant ‘EB 8-21’, in contrast, has a date of fruit harvesting which is considered to be very early in the season, and which additionally produces very large fruit, and has an upright growth habit which is in contrast to the closest known variety.

BRIEF DESCRIPTION OF THE DRAWING

The accompanying drawings, which are provided are color photographs of the new blueberry plant.

FIG. 1 depicts several whole, mature fruit of the new and novel variety, sufficiently matured for harvesting and shipment. FIG. 1 further depicts a twig bearing typical leaves and showing the dorsal and ventral coloration thereof, and the general growth habit of the new variety.

FIG. 2 depicts a twig bearing typical leaves and which shows the dorsal and ventral coloration thereof.

The colors in these photographs are as nearly true as is reasonably possible in a color representation of this type. Due to chemical development, processing and printing, the leaves and fruit depicted in these photographs may or may not be accurate when compared to the actual specimen. For this reason, future color references should be made to the common color description as provided hereinafter.

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.

DETAILED DESCRIPTION

Referring more specifically to the botanical details of this new and distinct variety of blueberry plant, the following has been observed during the sixth fruiting season under the ecological conditions prevailing at the farm of the inventor, which is located in Yanchep Springs, Yanchep Western Australia.
