RELATED APPLICATION DATA

The present application claims priority to Australian Plant Breeders Rights application Serial No. 2012/116, 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 8-1’.

ORIGIN

The present variety of blueberry resulted from an ongoing development program which I've 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 8-1’ 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 plant was derived from a controlled cross-pollination of the seed parent, blueberry plant ‘03-6’ [unpatented], and a pollen parent, blueberry plant ‘99-41’ [unpatented] during the 2005 growing season. The seed parent blueberry plant ‘03-6’ [unpatented] is principally characterized by a semi-spreading growth habit, and which further has an early season for flowering. Still further, the fruit produced by the seed parent is medium to large in size in relative comparison to other varieties. On the other hand, the pollen parent, blueberry plant ‘99-41’ is characterized by a spreading growth habit and an early season of flowering in relative comparison to other varieties. Additionally, the pollen parent produces relatively large sized fruit. The resulting seed derived from the seed parent, as noted above, produced approximately 500 plants. The fruit of these new plants were assessed in 2007. A further assessment was conducted in 2008. At that time, the new variety ‘EB 8-1’ was selected for further propagation. Further asexual reproduction of the new variety ‘EB 8-1’ has led to the conclusion that it is a distinct and new variety of blueberry plant. Additional vegetative propagation has occurred during the 2009 through 2011 growing seasons. The present new variety of blueberry plant is considered to be novel in view of its production of extra large sized fruit, and which further has a small, dry picking scar. Additionally, the new blueberry plant has a very good fruit flavor and produces early flowers. Still further, the fruit of the new variety is ripe for harvesting at a date earlier in the season in relative comparison to other known varieties.

In comparison to the seed parent blueberry plant ‘03-6,’ the present, new variety of blueberry plant, produces fruit which will mature for harvesting and shipment early in the growing season, under the ecological conditions prevailing in Yanchep, Western Australia. This date of maturity is before the date of maturity of the seed parent ‘03-6,’ and which is mature for harvesting and shipment in the early to mid-season, under the ecological conditions prevailing in Yanchep, Western Australia. Still further, the new variety of blueberry plant produces fruit having a size, which is considered very large in relative comparison to the medium sized fruit produced by the seed parent blueberry plant ‘03-6.’ Furthermore, the new variety of blueberry plant has a growth habit which is considered to be spreading in relative comparison to the bushy to spreading growth pattern as typically displayed by the seed parent blueberry plant ‘03-6.’ Moreover, the new blueberry plant produces fruit which are clearly distinguishable from that of the seed parent. The new and novel blueberry plant has a fruit shape, which is considered to be flattened, and globose as opposed to the globose shape of the fruit produced by the seed parent ‘03-6.’

In relative comparison to the pollen parent, that being blueberry plant ‘99-41,’ the pollen parent produces fruit which are ripe for harvesting and shipment in the mid to late season, under the ecological conditions prevailing in Yanchep, Western Australia. As noted above, the new and novel variety of blueberry plant is ripe for harvesting and shipment in the early season, under the ecological conditions existing in Yanchep, Western Australia. In comparison to the pollen parent, which produces small to medium sized fruit, the new and novel blueberry plant, as described herein, produces very large fruit under the growing conditions prevailing in Yanchep, Western Australia. Again, as noted above, the growth habit of the new variety of blueberry plant is spreading. This is in contrast to the growth habit of the pollen parent, blueberry plant ‘99-41,’ which has an upright growth habit. Again, the fruit shape of the new and novel blueberry plant is considered flattened, and globose. This is in contrast to the fruit shape of the pollen parent, blueberry ‘99-41’ [unpatented] and which produces fruit which are globose in shape.

The present, and new and novel variety of blueberry plant ‘EB 8-1’ is distinguishable from the most closely related variety, which is the ‘Sharpeblue’ blueberry plant [unpatented]. In this regard, the ‘Sharpeblue’ blueberry plant is well known, and is widely grown by both commercial growers and homeowners. The ‘Sharpeblue’ blueberry plant produces fruit which are ripe for harvesting and shipment early to mid season and further has a fruit size which is considered to be medium in relative comparison to other varieties. Still further, the ‘Sharpeblue’ blueberry plant has a bushy to spreading growth pattern and a fruit shape which is considered to be globose. In contrast, the new variety is ripe for harvesting and shipment early in the season, and further produces fruit having a very large fruit size. Additionally, the new variety of blueberry plant has a spreading growth pattern, and further the fruit shape is considered to be flattened and globose. The asexual propagation of the present plant was accomplished by means of cuttings. My observations of the new and novel plant over a number of years has confirmed the characteristics of the present variety across these multiple generations.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying drawing which is provided is a color photograph of the new blueberry plant.

FIG. 1 illustrates the new variety of blueberry plant ‘EB 8-1’ and shows a portion of a vegetative stem showing the growth habit of the leaves; several leaves are further illustrated showing the dorsal and ventral coloration, thereof, and the relative sizes of several fruit are depicted showing both the dorsal and ventral coloration, and morphology of same. FIG. 1 additionally shows a vegetative stem, leaves, and fruit produced by the closest known variety, that being the ‘Sharpeblue’ blueberry plant.

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 specimen. For this reason, future color references should be made to the color plates as provided by The Royal Horticulture Society Colour Charts (5^thEdition), and other color descriptions provided hereinafter. Common color names are also employed, hereinafter.
