Blueberry plant, ‘EB 8-30’

Abstract

A new and distinct variety of blueberry plant, which is denominated varietally hereinafter as ‘EB 8-30’ is described, and which produces an attractively colored berry, which is mature for harvesting and shipment in the mid-season, and which further is medium to large in size, and wherein the blueberry plant has an semi-upright growth habit, all when grown under the ecological conditions prevailing in Yanchep, Western Australia.

Description

Latin name: ‘Vaccinium Hybrid’.

Varietal denomination: ‘EB 8-30’.

RELATED APPLICATION DATA

The present application claims priority from Australian Plant Breeders Rights Application Serial No. 2012/115, and which was filed on 14 Jun. 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, hereinafter, as ‘EB 8-30’.

ORIGIN AND ASEXUAL REPRODUCTION

The present variety of blueberry plant resulted from an ongoing program of plant development. The purpose of this program is to improve the commercial quality of blueberry plants by creating and releasing promising selections each year, in order to produce plant populations from which improved progenies are evaluated and selected. The new blueberry plant ‘EB 8-30’ was originated by me and selected from a population of new plants growing on my farm, which is located near Yanchep Springs, Yanchep, Western Australia. The new variety of blueberry plant was derived from a cross that I made in 2005 of the blueberry seed parent ‘Compact 36’ [unpatented], and the pollen parent, blueberry plant ‘99-12’ [unpatented]. The seed parent is a compact bush which displays early season flowering, and which further produces small to medium sized fruit. On the other hand, the pollen parent is characterized by a semi-spreading growth habit and which further produces large, early maturing fruit. Seed derived from the seed parent ‘Compact 36’ produced approximately 300 plants. These new plants were grown and the first fruit was evaluated in 2007. Still further, a second assessment was conducted during the 2008 growing season, and this resulted in the selection of ‘EB 8-30’ as having particularly desirable traits. Subsequently, the new variety ‘EB 8-30’ was asexually reproduced by cuttings and these further plants were assessed during subsequent 2009 through 2012 growing seasons. These further evaluations led to the conclusion that the new variety ‘EB 8-30’ is a distinct and suitable commercial variety for commercial, and retail use.

In relative comparison to the seed parent, ‘Compact 36’, the new variety ‘EB 8-30’ is principally characterized as a novelty by producing fruit which are mature for harvesting in the mid-season, and further produces medium to large fruit, and which additionally displays a compact growth habit. In contrast, the seed parent produces fruit which are ripe for harvesting in the mid to late season, and has a fruit size which is only average to medium, and further has a semi-upright growth habit. In relative comparison to the pollen parent blueberry plant ‘99-12,’ the new variety ‘EB 8-30’ again produces fruit in the mid-season, which is medium to large in size, and which further has a compact growth habit. However, the pollen parent produces fruit which are ripe for harvesting in the mid to late season; produces small to medium sized fruit; and has a growth habit which is considered more upright.

BRIEF DESCRIPTION OF THE DRAWING

FIG. 1 depicts six whole fruit sufficiently matured for harvesting and shipment, a twig bearing typical leaves showing the dorsal and ventral coloration, and growth habit thereof, and five leaves showing the dorsal and ventral coloration thereof. In addition, FIG. 1 shows the closest known variety, that being to ‘Sharpeblue’ blueberry plant [unpatented], which again shows six fruit which are sufficiently mature for harvesting and shipment, a twig bearing typical leaves, and five leaves showing the dorsal and ventral coloration so that the two blueberry varieties can be compared, one with the other.

The color in this photograph is 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 color descriptions as provided in The Royal Horticulture Society Colour Charts (5^th Edition) hereinafter.

The following detailed description has been prepared to solely 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 as set forth, 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 my farm, which is located near Yanchep Springs, Western Australia. Common color names are also occasionally used.

PLANT

• Plant vigor: Considered average for the species. This is in contrast to the closest known variety the ‘Sharpeblue’ blueberry plant, and which has a displayed plant vigor which is considered medium to strong.
• Plant growth habit: Considered semi-upright. This is in contrast to the closest known variety which has an upright growth habit.
  • • Average plant size.—1.6 meters in height, and 1.2 meters in width.
• One year old shoots:
  • • Color.—Yellow-Green, (RHS 145A).
• One year old shoots:
  • • Internode length.—Considered average for the species. This is in contrast to the closest known variety, as noted above, and which has internode lengths that are considered medium to long.

LEAF

• Leaf length: Considered average for the species, about 56 mm. This is in contrast to the closest known variety, which displays a leaf length which is considered to be medium to long.
• Leaf width: Considered narrow to medium for the species, about 30 mm. This is in contrast to the closest known variety the ‘Sharpeblue’ blueberry plant, which has a leaf width which is considered medium to broad. This distinction can be best seen in FIG. 1.
