Abstract

The new blueberry plant variety ‘MG09768-05-002’ is provided. ‘MG09768-05-002’ is a commercial variety intended for the fresh fruit market. The variety is produced from a cross of ‘Magnolia’ and ‘Caroline’, which can be distinguished by its outstanding features.

Description

Latin name of the genus and species:
Genus—Vaccinium.
Species—hybrid.
Variety denomination: The new blueberry plant claimed is of the variety denominated ‘MG09768-05-002’.
BACKGROUND OF THE INVENTION
The proposed new Vaccinium variety ‘MG09768-05-002’ was selected as a seedling from a controlled pollination involving southern and northern highbush varieties ‘Magnolia’ (seed parent) (not patented) and ‘Caroline’ (pollen parent) (not patented) respectively. The cross was made in 2009 in Moondarra, Victoria, Australia and the variety was first selected in 2016 in Moondarra, Victoria, Australia. This new cultivar has been asexually propagated through cuttings since 2016 and grown in replicated field trials from 2017 in Moondarra, Victoria, Australia.
The fruit of ‘MG09768-05-002’ is large and crunchy with excellent flavor, good bloom and a small dry scar. The bush is very vigorous with an upright growth habit.
SUMMARY OF THE INVENTION
As mentioned above, the proposed new variety is a result of the cross of ‘Magnolia’ and ‘Caroline’.
The seed parent ‘Magnolia’ was selected in Poplaville, Miss. in 1982 in respect to its early fruit ripening, low chill requirement, vigorous growth, medium sized/firm fruit with good flavor.
The pollen parent was produced from open pollinated ‘Lateblue’ (not patented) seeds sent to the Knoxfield Horticultural Research Institute in Victoria, Australia in 1976, and was selected based on its medium timing of fruit ripening, strong aromatic flavor, medium firmness and moderate bush vigor.
The proposed new variety ‘MG09768-05-002’ is a resulting selection from seedlings produced out a controlled pollination event between ‘Magnolia’ and ‘Caroline’ in the breeding program at Moondarra, Victoria, Australia in 2009.
Asexual reproduction of the proposed new variety ‘MG09768-05-002’ via softwood cuttings has occurred since 2016 at Moondarra, Victoria, Australia. This has demonstrated that the new variety is uniform, stable and true to type over successive generations of asexual propagation in respect to the characteristics aforementioned.
The proposed new cultivar ‘MG09768-05-002’ was selected as a single plant in a population of seedlings resulting from a cross between the southern highbush variety ‘Magnolia’ and northern highbush variety ‘Caroline’ being selected in 2016 at Moondarra, Victoria, Australia. Its selection was based on the criteria of strong bush vigor, mid-season fruit ripening, large/crunchy berry with an excellent flavor and good bloom. The selection has been evaluated in field trials at Moondarra, Victoria, Australia since 2017.
The following characteristics of the proposed new variety have been observed and used to distinguish ‘MG09768-05-002’ as a distinct cultivar of Vaccinium hybrid:
    • Mid-season fruit ripening.
    • Strong plant vigor.
    • Upright/whippy growth habit.
    • Large berry size.
    • Crunchy berry texture.
    • Small dry picking scar.
The proposed new variety ‘MG09768-05-002’ is uniform, stable and true to type over successive generations of asexual propagation through softwood cuttings in respect to the characteristics aforementioned.
The new cultivar ‘MG09768-05-002’ differs from the seed parent ‘Magnolia’ previously described in terms of its mid-season fruit ripening, higher chill requirement, larger berry size and crunchy berry texture.
‘MG09768-05-002’ differs from pollen parent ‘Caroline’ in respect to a larger berry size, crunchy berry texture and strong bush vigor.
BRIEF DESCRIPTION OF THE DRAWINGS
The accompanying photographic illustration shows typical specimens in full color of the foliage and fruit of the new variety ‘MG09768-05-002’. ‘MG09768-05-002’ has been labeled NB-5-2 in the photographs. The colors are as nearly true as is reasonably possible in a color representation of this type.
FIG. 1 is a photograph of the new variety ‘MG09768-05-002’, demonstrating the plant's upright/whippy growth habit at age 6-7 years.
FIG. 2 is a photograph of the fruit of the new variety ‘MG09768-05-002’ at age 6-7 years.
The colors in the photographs are as close as possible with the photographic and printing technology utilized. The color values cited in the detailed botanical description accurately describe the colors of the new blueberry.
DETAILED BOTANICAL DESCRIPTION
