BACKGROUND OF THE INVENTION

The present invention relates to the discovery of a new and distinct cultivar of rabbiteye blueberry known as a Vaccinium virgatum referred to as ‘Overtime,’ as herein described and illustrated.

The new blueberry plant variety ‘Overtime’ was selected in Lowell, Oreg. in 2006. ‘Overtime’ is a commercial variety intended for the hand harvest fresh market. The variety has medium sized, light blue fruit which has an excellent fruity flavor and lacks the typical grittiness of rabbiteye blueberries. ‘Overtime’ ripens about one week earlier than ‘Powderblue’ and ‘Ochlockonee’ (U.S. Plant Pat. No. 17,300), and has comparable yields. The variety shows good tolerance to bacterial canker caused by Pseudomonas syringae.

Pedigree and History: The new blueberry plant originated from a cross of ‘Centurion’ (female parent, unpatented) by ‘Powerblue’ (pollen parent, unpatented). The new blueberry plant variety ‘Overtime’ has been planted in replicated trials since 2007.

The new variety can be compared to commercial variety ‘Ochlockonee’ in that ‘Overtime’ has larger berries and ripens about one week earlier.

The new variety can be compared to commercial variety ‘Powerblue’ in that ‘Overtime’ has larger berries with better flavor, and ripens about one week earlier.

The new blueberry plant variety ‘Overtime’ has maintained its distinguishing characteristics throughout successive asexual propagations. The variety has been repeatedly asexually reproduced through softwood cuttings in Lowell, Oreg., and the clones are phenotypically identical to the original plant.

SUMMARY OF THE INVENTION

The new blueberry plant variety ‘Overtime’ has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment and cultural practices such as temperature and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed in Lowell, Oreg., and are determined to be the unique characteristics of the new blueberry plant variety ‘Overtime’:

• • 1. Medium sized, round fruit with excellent fruity flavor, and smooth texture.
  • 2. Very good performance in storage trials.
  • 3. Good tolerance to bacterial canker caused by Pseudomonas syringae.

BOTANICAL DESCRIPTION

The following detailed description sets forth the distinctive characteristics of ‘Overtime.’ 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 three years of age, and the descriptions relate to plants grown in the field in Lowell, Oreg. Color designations are from “The Pantone Book of Color” (by Leatrice Eiseman and Lawrence Herbert, Harry N. Abrams, Inc., Publishers, New York, 1990). Where the Pantone color designations differ from the colors in the photographs, the Pantone colors are accurate.
