Abstract

A new and distinct variety of blueberry plant named ‘DrisBlueTen’ particularly distinguished by having an early harvest season, strong vigor and large, firm berries, is disclosed.

Description

Genus and species: Vaccinium corymbosum L.

Variety denomination: ‘DrisBlueTen’.

BACKGROUND OF THE NEW PLANT

The invention relates to a new and distinct blueberry variety designated ‘DrisBlueTen’ and botanically known as Vaccinium corymbosum L. This new blueberry variety was discovered in Santa Cruz County, Calif. in September 2003 and originated from a cross between the female parent blueberry plant ‘Nui’ (U.S. Plant Pat. No. 6,699) and the proprietary male parent blueberry plant ‘MS122’ (unpatented). The original seedling of the new variety was first asexually propagated via softwood cuttings at a nursery in Monterey County, Calif. in 2002. ‘DrisBlueTen’ was subsequently asexually propagated via softwood cuttings and underwent further testing at a nursery in Santa Cruz County, Calif. for eight years (2005-2012). The present invention has been found to be stable and reproduce true to type through successive asexual propagations via softwood cuttings.

Plant Breeder's Rights for this variety have not been applied for. ‘DrisBlueTen’ has not been made publicly available or sold more than one year prior to the filing date of this application.

SUMMARY OF THE INVENTION

The following are the most outstanding and distinguishing characteristics of this new cultivar when grown under normal horticultural practices in Santa Cruz County, Calif.

- 1. Early harvest season;
- 2. Strong vigor; and
- 3. Large, firm berries.

DESCRIPTION OF THE PHOTOGRAPHS

This new blueberry plant is illustrated by the accompanying photographs which show fruit of the plant as well as the flowers and leaves. The colors shown are as true as can be reasonably obtained by conventional photographic procedures. The photographs are of plants that are four years old.

FIG. 1 shows a close-up of the mature flowers.

FIG. 2 shows a close-up of the leaves.

FIG. 3 shows a close-up of the whole fruit and a cross-section of the fruit.

DESCRIPTION OF THE NEW CULTIVAR

The following detailed description sets forth the distinctive characteristics of ‘DrisBlueTen’. The data which define these characteristics is based on observations taken in Santa Cruz County, Calif. from 2005-2012. This description is in accordance with UPOV terminology. Color designations, color descriptions, and other phenotypical descriptions may deviate from the stated values and descriptions depending upon variation in environmental, seasonal, climatic and cultural conditions. ‘DrisBlueTen’ has not been observed under all possible environmental conditions. The botanical description of ‘DrisBlueTen’ was taken from 4 year-old plants. Color references are primarily to The R.H.S. Colour Chart of The Royal Horticultural Society of London (R.H.S.) (2007 edition). Descriptive terminology follows the Plant Identification Terminology, An Illustrated Glossary, 2^ndedition by James G. Harris and Melinda Woolf Harris, unless where otherwise defined.

COMPARISON WITH PARENTAL AND COMMERCIAL VARIETIES

‘DrisBlueTen’ differs from the female parent ‘Nui’ (U.S. Plant Pat. No. 6,699) in that ‘DrisBlueTen’ ripens earlier than ‘Nui’ and has fruit that is smaller size than ‘Nui’.

‘DrisBlueTen’ differs from the commercial variety ‘Elliott’ (unpatented) in that ‘DrisBlueTen’ has large berries with medium to high sweetness, whereas ‘Elliott’ has medium to large sized berries that are quite tart unless picked fully ripe.

‘DrisBlueTen’ differs from the commercial variety ‘Bluecrop’ (unpatented), in that ‘DrisBlueTen’ has a semi-erect to spreading growth habit, whereas ‘Bluecrop’ has an upright growth habit. Additionally, ‘DrisBlueTen’ has an early harvest season, whereas ‘Bluecrop’ has a mid-season harvest.
