Southern Highbush Blueberry Variety

General Description

Kestrel™ ‘FL02-40’ is a southern highbush blueberry variety developed at the University of Florida’s Institute of Food and Agricultural Sciences blueberry breeding program.  Kestrel™ ‘FL02-40’ is noted for its early-ripening, high evergreen potential, and superior berry quality.

 

Fruit of Kestrel™ ‘FL02-40’ ripen very early, and berries remain sweet even as hues of blues emerge.  Flowers of Kestrel™ ‘FL02-40’ open around January 30, and berries ripen around April 22.  Berries of Kestrel™ ‘FL02-40’ average 2.40 grams.  The berry quality of Kestrel™ ‘FL02-40’ is excellent, as the plant produces berries that are plump, firm, and aromatic.  Kestrel™ ‘FL02-40’ produces medium loose berry clusters with very low berry detachment force.  Additionally, plants of Kestrel™ ‘FL02-40’ demonstrate prolific early leafing, and this variety has done well in tests of the evergreen production system.

 

  • Very early fruit season production

  • Vigorous, spreading, good field survival

  • EXCELLENT flavor and aroma

  • Good evergreen potential

  • Low berry detachment force when ripe

 

Fruit quality under optimal picking conditions (average of several years):

  • Large Fruit Weight/Size (2.4 grams/21.2 mm) similar to ‘Emerald’

  • Higher Fruit Brix levels (11.8) than ‘Emerald’ with great aroma

  • Slightly Higher Fruit Firmness (199.6 g/mm) than ‘Emerald’

Performance 2018-2019 Season

Fruit Quality and Yield

The following plots show the most important fruit quality traits and yield, across the season.

The vertical lines in the yield plots indicate when 10%, 50% and 90% of the harvest was achieved during the season.

 

Dotted lines indicate the desired values for new cultivars:

 

  • Berry weight greater than 2g

  • Fruit Diameter greater than 14mm

  • Firmness higher than 150g/mm

  • Brix higher than 10%

  • TTA less than 1%

  • Brix/TTA higher than 14 units

 

Warning: Yield plot coming from harvesting of two bushes. Values may seem overestimated as all the fruit from the bush is harvested, and because this is harvest yield and no packed yield. Use this data to compare among cultivars and no to predict potential yield on your farm.

 

Measurements are in grams (g). To convert from grams to pounds (lb) use the following formula:

lb of fruit per bush = (g of fruit) x (0.002204)
