USPP26597P2 - Blueberry plant named ‘OBF0627’ - Google Patents

Abstract

A new and distinct cultivar of Northern Highbush Blueberry plant characterized by its extremely firm fruit and the concentrated ripening of its berries. It an excellent berry for mechanical harvest and the extra firm berries give it a long shelf life. In addition the new cultivar produces mid to late-season, has a medium sweet, floral flavor, small, dry stem scars, an upright moderately spreading habit, and excellent vigor.

Description

Botanical classification: Vaccinium corymbosum.

Variety nomination: ‘OBF0627’.

FIELD

The present invention relates to a new and distinct cultivar of Northern Highbush blueberry, or Vaccinium corymbosum and given the name ‘OBF0627’. Vaccinium corymbosum is of the family Ericaceae.

BACKGROUND

Northern Highbush blueberries are the most commonly planted blueberries used for commercial and home production of fruit in the Northern U.S. and Canada. The new cultivar is from a planned breeding program for an improved blueberry. It was developed at a blueberry farm in Silverton, Oreg. using open pollination with unnamed seedlings for the parents.

This new Northern Highbush Blueberry is uniquely distinguished by its extremely firm fruit and the concentrated ripening of its berries. It is an excellent berry for mechanical harvest and the extra firm berries give a long shelf life. In addition the new cultivar produces mid to late-season, has a medium sweet, floral flavor, small, dry stem scars, and has an upright moderately spreading compact habit.

Compared to Vaccinium corymbosum ‘Draper’, U.S. Plant Pat. No. 15,103, the new cultivar has firmer berries, a smaller habit, and a later fruiting season.

Compared to Vaccinium corymbosem ‘06-22’, U.S. Plant patent application Ser. No. 13/998,303, the new cultivar has a more spreading habit and a medium sweet, floral berry flavor rather than sweet-tart.

Asexual propagation by stem tip cuttings in Silverton, Oreg., shows that the foregoing characteristics and distinctions come true to form and are established and transmitted through succeeding propagations. The present invention has not been evaluated under all possible environmental conditions. The phenotype may vary with changes in environment without a change in the genotype of the plant.

SUMMARY

The foregoing and other objects, features, and advantages of the invention will become more apparent from the following detailed description, which proceeds with reference to the accompanying figures.
