Family—Ericaceae
Genus—Vaccinium
Species—corymbosum hybrid
The new blueberry plant claimed is of the variety denominated ‘C03-158.’
The present invention relates to a new and distinct perennial variety of Vaccinium corymbosum hybrid (blueberry), which has been given the variety denomination of ‘C03-158.’ The new variety ‘C03-158’ shows distinctive traits such as early season, good flavor and firm fruit. Its market class is that of a fruiting plant. The new variety ‘C03-158’ 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 2001 from a cross of the blueberry variety known as ‘Emerald’ (seed parent) (U.S. Plant Pat. No. 12,165) and the blueberry variety known as ‘F97-169’ (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 2003 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 ‘C03-158.’ Selection criteria were a combination of early season, low chilling requirement, medium fruit of good flavor, firm fruit. 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 ‘C03-158’ by softwood cutting propagation since 2003 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 ‘Emerald’ is characterized by a late-very late timing of ripening of fruit. The pollen parent ‘F97-169’ is characterized by an early timing of ripening of fruit. The new variety ‘C03-158’ differs from the seed parent ‘Emerald’ in that ‘C03-158’ has an earlier cropping timing, averaging 30 days earlier than ‘Emerald.’ The new variety ‘C03-158’ has maintained its distinguished characteristics throughout successive asexual propagation.
The following characteristics of the new variety have been repeatedly observed and can be used to distinguish ‘C03-158’ as a new and distinct variety of Vaccinium corymbosum hybrid:
1. medium fruiting season
2. strong plant vigor
3. medium fruit size
4. good flavor
5. firm fruit
Plants of the new variety ‘C03-158’ differ from plants of the seed parent ‘Emerald’ primarily in that ‘C03-158’ has a medium season cropping timing, averaging 30 days earlier than ‘Emerald.’ The new blueberry variety ‘C03-158’ has maintained its distinguished characteristics throughout successive asexual propagation.
The accompanying photographic illustration shows typical specimens in full color of the foliage and fruit of the new variety ‘C03-158.’ The colors are as nearly true as is reasonably possible in a color representation of this type.
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.
The following detailed description sets forth the distinctive characteristics of ‘C03-158.’ 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 5 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 RHS Chart—edition 2007.
