Abstract

The new blueberry plant variety ‘C08-141’ is provided. ‘C08-141’ is a commercial variety intended for the fresh market. The variety is produced from a cross of ‘FL00-057’ and ‘C99-042’, which can be distinguished by its outstanding features.

Description

Latin name of the genus and species:

Genus—Vaccinium.

Species—corymbosum hybrid.

Variety denomination: The new blueberry plant claimed is of the variety denominated ‘C08-141’.

BACKGROUND OF THE INVENTION

The new variety ‘C08-141’ was selected from a population of seedlings derived from crossing the blueberry varieties known as ‘FL00-057’ (seed parent) (not patented)) and the variety known as ‘C99-042’ (U.S. Plant Pat. No. 20,695) (pollen parent). The cross was made in 2006 in Florida, USA and the seed was sown and grown on in Corindi Beach, NSW, Australia. The new variety was selected in 2008 from among plants located on land at Corindi Beach and assigned the breeding code ‘C08-141’. Plants of ‘C08-141’ were propagated by cuttings for further evaluation and resulted to be uniform and stable. The new variety showed distinctive traits such as evergreen, vigorous, good flavor and firm fruit.

SUMMARY OF THE INVENTION

The new variety ‘C08-141’ was originated from a cross of ‘FL00-057’ (seed parent) and the variety known as ‘C99-042’ in 2006 in Florida, USA. The pollen parent is characterized by an early to mid-season timing of fruit ripening, it is evergreen, its fruit is of high firmness.

The new blueberry variety resulted from seedlings produced in a controlled breeding programme. The cross was made in 2006 in Florida, USA and the seed was sown and grown on in Corindi Beach, NSW, Australia.

The new variety was selected in 2008 from among plants located on land at Corindi Beach and has since been named ‘C08-141’. Since then plants of ‘C08-141’ were propagated by cuttings for further evaluation and resulted to be uniform and stable. Asexual reproduction of the new variety ‘C08-141’ by cutting propagation since 2008 at Corindi Beach, NSW, Australia has demonstrated that the new variety reproduces true to type plants.

The new variety was selected in 2008 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 early to mid-season, low chilling requirement, strong vigour, non-deciduous type of plant (evergreen), large fruit size, good fruit flavor and firm fruit. 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 ‘C08-141’ as a new and distinct variety of Vaccinium corymbosum hybrid:

- 1. Non-deciduous (Evergreen)
- 2. Early to medium season crop
- 3. Strong plant vigour
- 4. Low chilling requirement
- 5. Large fruit size
- 6. Good fruit flavor
- 7. Firm fruit

The new variety differed from the male parent ‘C99-042’ in that ‘C08-141’ has a higher vigour and a larger fruit size. The new blueberry variety ‘C08-141’ has maintained its distinguished characteristics throughout successive asexual propagation. The variety has been repeatedly asexually reproduced thought softwood cuttings in NSW, Australia and the clones are phenotypically identical to the original plant.
