The invention claimed is:

1. A new and distinct variety of blueberry plant named ‘C05-178,’ substantially as illustrated and described herein.

Description:

Latin name of the family, genus, and species: Family—Ericaceae. Genus—Vaccinium. Species—corymbosum hybrid.

Variety denomination: The new blueberry plant claimed is of the variety denominated ‘C05-178.’

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct perennial variety of Vaccinium corymbosum hybrid (blueberry), which has been given the variety denomination of ‘C05-178.’ The new variety ‘C05-178’ shows distinctive traits such as strong growth vigor, fruit with strong firmness, low chilling requirement. The new variety ‘C05-178’ is intended for use as fresh fruit for shipping, customer pick and processing markets and as a home garden plant.

The new blueberry cultivar is a selection resulting from seedlings produced in a controlled breeding programme of Vaccinium varieties in Florida, USA in 2003 from a cross of the blueberry variety known as ‘Early crisp’ (seed parent) (unpatented) and the blueberry variety known as ‘FL03-061’ (pollen parent) (unpatented). The seed from the cross was sown and grown in Corindi Beach, New South Wales, Australia. The new cultivar was discovered and selected in 2005 as a single plant within a population of seedlings resulted from the controlled cross, in an experimental block in the field at Corindi Beach, New South Wales, Australia, and has since been named ‘C05-178.’ Selection criteria were a combination of strong growth vigor, low chilling requirement and fruit with strong firmness. The new variety was subsequently evaluated for a number of years at the commercial farm at Corindi Beach, New South Wales, Australia.

Asexual reproduction of the new variety ‘C05-178’ by softwood cutting propagation since 2005 at Corindi Beach, New South Wales, Australia has demonstrated that the new variety reproduces true to type with all of the characteristics, as herein described, firmly fixed and retained through successive generations of such asexual propagation, with the clones phenotypically identical to the original plant.

The seed parent ‘Early crisp’ is characterized by an early timing of ripening of fruit. The pollen parent ‘FL03-061’ is characterized by a late to very late timing of ripening of fruit. The new variety ‘C05-178’ differs from the seed and pollen parents in that ‘C05-178’ has a mid-season cropping time, ripening after ‘Early Crisp’ and before ‘FL03-061.’ The new variety ‘C05-178’ has maintained its distinguished characteristics throughout successive asexual propagation.

SUMMARY OF THE INVENTION

The new blueberry variety originated from a cross of ‘Early crisp’ (seed parent) and the variety known as ‘FL03-061’ (pollen parent) in 2003 Florida, US. The seed parent is characterized by an early timing of ripening of fruit. The pollen parent is characterized by a late to very late timing of ripening of fruit.

The new blueberry variety ‘C05-178’ resulted from seedlings produced in a controlled breeding program. The cross was made in 2003 in Florida, USA and the seed was sown and grown on in Corindi Beach, NSW, Australia.

The new variety was selected in 2005 from among plants located on land at Corindi Beach and has since been named ‘C05-178’. Since then plants of ‘C05-178’ were propagated by cuttings for further evaluation and resulted to be uniform and stable. Asexual reproduction of the new variety ‘C05-178’ by cutting propagation since 2005 at Corindi Beach, NSW, Australia, has demonstrated that the new variety reproduces true to type plants.

The new variety was selected in 2005 as a single plant within a population of seedlings resulting from controlled cross of Vaccinium varieties. The seedling population was planted in an experimental block in the field at Corindi Beach, NSW, Australia and the selection of the new variety took place in the same block. Selection criteria were a combination of strong growth vigor, semi-upright habit and large fruit with strong firmness. The new variety was subsequently evaluated for a number of years at the commercial farm at Corindi Beach, NSW, Australia.

The following characteristics of the new variety have been repeatedly observed and can be used to distinguish ‘C05-178’ as a new and distinct variety of Vaccinium corymbosum hybrid:

    • Strong growth vigor
    • Semi-upright plant growth habit
    • Mid-season
    • Large fruit size
    • Fruit with strong firmness and crispy skin

The new variety differs from the female (‘Early crisp’—early cropping) and male (‘FL03-061’—late to very late cropping) parents in that ‘C05-178’ has a mid-season cropping timing. The new variety ‘C05-178’ has maintained its distinguished characteristics through successive asexual propagation. The variety has been repeatedly asexually reproduced through softwood cuttings in NSW, Australia, and the clones are phenotypically identical to the original plant.

DETAILED BOTANICAL DESCRIPTION

The following detailed description sets forth the distinctive characteristics of ‘C05-178.’ The data which defines these characteristics was collected from asexual reproductions of the original selection. Dimensions, sizes, colors, and other characteristics are approximations and averages set forth as accurately as possible. The plant history was taken on plants approximately 4 years of age, and the descriptions relate to plants grown in the field in Corindi Beach, New South Wales, Australia. Descriptions of fruit characteristics were made on fruit grown in Corindi Beach, New South Wales, Australia. Color designations are from R.H.S. Chart—edition 2007.
