Blueberry plant named ‘ZF08-029’

Abstract

The new blueberry plant variety ‘ZF08-029’ is provided. ‘ZF08-029’ is a commercial variety intended for the hand harvest fresh fruit market. The variety is produced from a cross of ‘G-344’ (female parent, not patented) and ‘Draper’ (male parent, U.S. Pat. No. 15,103), which can be distinguished by its outstanding features.

Description

Latin name of the genus and species: Vaccinium corymbosum.

Variety denomination: The new blueberry plant claimed is of the variety denominated ‘ZF08-029’.

STATEMENT REGARDING FEDERALLY-SPONSORED RESEARCH AND DEVELOPMENT

None.

BACKGROUND OF THE INVENTION

The present invention relates to the discovery of a new and distinct cultivar of northern highbush blueberry (Vaccinium corymbosum L. hybrid) plant, referred to as ‘ZF08-029’, as herein described and illustrated. ‘ZF08-029’ is a commercial blueberry variety intended for both the fresh and processed fruit markets. The variety has high plant vigor, a semi-sprawling, rounded growth habit, ripens mid-season, and produces medium sized fruit with good firmness. ‘ZF08-029’ was selected for its above average fruit quality, specifically its highly aromatic, peach type flavor.

‘ZF08-029’ has a more rounded and vigorous growth habit, and more flavorful, though smaller, fruit than ‘Draper’ (U.S. Pat. No. 15,103), the male parent. Compared to the female parent ‘G-344’ (not patented), ‘ZF08-029’ appears to be more tolerant to cold temperatures.

Pedigree and History: The new blueberry plant originated from a cross of ‘G-344’ (female parent, not patented) and ‘Draper’ (male parent) made in Lowell, Oreg., USA in 2004 and was selected in the same location in 2008.

The new blueberry variety ‘ZF08-029’ was initially propagated by softwood cuttings in 2008 from the original seedling in Lowell, Oreg., USA and planted in a replicated plot of nine plants in fall 2009. The plants established in Oregon were successfully used to establish in vitro culture lines in 2012

‘ZF08-029’ was selected in 2008 because of its high-quality fruit—firm, crisp, peachy flavor, light blue color, and medium size. Beginning in 2011, ‘ZF08-029’ was evaluated for seven years in Lowell, Oreg. for plant performance, fruit quality, and yield in comparison to standard varieties like ‘Legacy’ (not patented) and ‘Draper’. Beginning in 2012, additional plots of ‘ZF08-029’ were established in other areas of Oregon, Northwest Washington and Central California. After extensive evaluation in these growing regions, ‘ZF08-029’ was determined to be sufficiently cold hardy and adaptable to varying soil conditions and commercial management strategies, and has a competitive yield for the harvest season. Plants of ‘ZF08-029’ propagated from softwood cuttings or in vitro are phenotypically stable and exhibit the same characteristics as the original plant.

SUMMARY OF THE INVENTION

The new blueberry plant variety ‘ZF08-029’ 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.

‘ZF08-029’ is distinguished by a rounded, semi-sprawling growth habit, high vigor, and complex fruit flavor. The following characteristics of the new cultivar have been repeatedly observed and are determined to be the unique characteristics of the new blueberry plant variety ‘ZF08-029’:

• • 1) Mid-season ripening
  • 2) Medium, uniform fruit size
  • 3) Aromatic, flavorful fruit with a firm texture

DETAILED BOTANICAL DESCRIPTION

The following detailed description sets forth the distinctive characteristics of ‘ZF08-029’. The data which define these characteristics were 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, unless otherwise noted, and the descriptions relate to plants grown in the field located at 39252 Jasper-Lowell Road, Lowell, Oreg., USA. Descriptions of fruit characteristics were made on fruit grown at the field described above. Color designations are from “The Pantone Book of Color” (by Leatrice Eiseman and Lawrence Herbery, Harry N. Abrams, Inc., Publishers, New York 1990). Where the Pantone color designations differ from the colors of the photographs, the Pantone colors are accurate.
