BLUBERRY PLANT NAMED C13-051

Abstract

The new blueberry plant variety ‘C13-051’ is provided. ‘C13-051’ is a commercial variety intended for the fresh market. The variety is produced from a cross of unpatented parents ‘FL09-001’ and ‘FL05-383’.

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 ‘C13-051’.

BACKGROUND OF THE INVENTION

The new variety ‘C13-051’ was selected from a population of seedlings derived from crossing the blueberry varieties known as ‘FL09-001’ (unpatented seed parent) and the variety known as ‘FL05-383’ (unpatented pollen parent). The cross was made in 2009 in Florida, USA and the seed was sown and grown in Corindi Beach, New South Wales, Australia. The new variety was selected in 2013 from among plants located on land at Corindi Beach and assigned the breeding code ‘C13-051’. Plants of ‘C13-051’ were propagated by cuttings for further evaluation and resulted to be uniform and stable. The new variety showed distinctive traits such as evergreen, with fruit of good flavor.

SUMMARY OF THE INVENTION

The new variety ‘C13-051’ was originated from a cross of ‘FL09-001’ (unpatented seed parent) and the variety known as ‘FL05-383’ (unpatented pollen parent) in 2009 in Florida, USA.

The new blueberry variety resulted from seedlings produced in a controlled breeding programme. The cross was made in 2009 in Florida, USA and the seed was sown and grown on in Corindi Beach, New South Wales, Australia.

The new variety was selected in 2013 from among plants located on land at Corindi Beach and has since been named ‘C13-051’. Since then plants of ‘C13-051’ were propagated by cuttings for further evaluation and confirmed to be uniform and stable. Asexual reproduction of the new variety ‘C13-051’ by cutting propagation since 2013 at Corindi Beach, New South Wales, Australia has demonstrated that the new variety reproduces true to type plants.

The new variety was selected in 2013 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, New South Wales, Australia and the selection of the new variety took place in the same block. Selection criteria were a combination of early to mid harvest season, low chilling requirement, medium to high vigour, non-deciduous type of plant (evergreen), large fruit size, good fruit flavor, and firm fruit. The new variety was subsequently evaluated for six years at the commercial farm at Corindi Beach, New South Wales, Australia.

The following characteristics of the new variety have been repeatedly observed and can be used to distinguish ‘C13-051’ as a new and distinct variety of Vaccinium corymbosum hybrid:

• • 1. Non-deciduous (Evergreen)
  • 2. Early to medium season crop
  • 3. High yield
  • 4. Low chilling requirement
  • 5. Large fruit size, average 3.1 g
  • 6. Excellent fruit flavor

The new blueberry variety ‘C13-051’ has maintained its distinguished characteristics throughout successive asexual propagation. The variety has been repeatedly asexually reproduced through softwood cuttings in New South Wales, Australia and the clones are phenotypically identical to the original plant.

DETAILED BOTANICAL DESCRIPTION

The following detailed description sets forth the distinctive characteristics of ‘C13-051’. 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. For all traits data was collected from 3 plant parts across 6 randomly selected plants. For the traits relating to fruits (e.g., fruit weight, firmness, brix, acidity) the data is an average across twenty fruits collected randomly. The plant history was taken on plants approximately 3 years of age, and the descriptions relate to plants grown in the field in Corindi Beach, New South Wales, 2456 Australia. Descriptions of fruit characteristics were made on fruit grown in Corindi Beach, New South Wales, 2456 Australia. Color designations are from the 2007 edition of The Royal Horticultural Society (“R.H.S.”).
