DETAILED BOTANICAL DESCRIPTION

(8) The following detailed description sets forth the distinctive characteristics of ‘C12-069’. 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.”) Colour Chart. ‘C12-069’ has not been observed under all possible environments. The phenotype may vary slightly with different growing environments such as temperature, light, fertility, soil pH, moisture, and maturity levels, but without any change in the genotype. Classification: a. Family.—Ericaceae. b. Genus.—Vaccinium. c. Species.—Corymbosum hybrid. d. Common name.—Blueberry. Parentage: Female parent.—Patented variety ‘FL98-325’. Male parent.—Unpatented selection ‘FL01-271’. Market class: Fresh market.
