Abstract:
A new and distinct cultivar of Northern Highbush blueberry plant characterized by its extra firm berry with a good sweet-tart flavor, upright, bush habit, medium-large berry size, and excellent vigor. In addition the new cultivar produces early to mid-season, has small, dry stem scars, and can be harvested mechanically.

Description:
Botanical classification:  Vaccinium corymbosum.    
     Variety nomination: ‘OBF0622’. 
     FIELD 
     The present invention relates to a new and distinct cultivar of Northern Highbush blueberry, or  Vaccinium corymbosum  and given the name ‘OBF0622’.  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:
         1. extra firm berry with a good sweet-tart flavor,   2. upright, bush habit,   3. medium-large berry size,   4. and excellent vigor.       

     In addition the new cultivar produces early to mid-season, has small, dry stem scars, and can be harvested mechanically. 
     Compared to  Vaccinium corymbosum  ‘Draper’, U.S. Plant Pat. No. 15,103, the new cultivar has a sweeter, firmer berry. 
     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.
