U.S. Patent PP27,740
Southern Highbush Blueberry Variety
Patrecia is late blooming but early fruit set, with high yield potential. Produces large berries in the early-mid part of the season.
Cultivar name: Patrecia (“UF52-20”)
Recommended for Florida: yes
FL region best adapted to: north-central Florida
Production system: deciduous
Hydrogen cyanamide: recommended; required for leafing and early season production.
Machine Harvestability: no data yet; however, berries of Patrecia grow in tight clusters, which may make machine harvesting this variety difficult.
Per plant yields (Density 1,452-1,742 plants/acre):
o North-central FL (2018-2020) 3.1 – 10.8 lbs/plant; average 8.5 lbs/plant
Known disease susceptibility: none observed to date
Known insect damage susceptibility: none observed to date
Fruit quality data:
o Fruit firmness: 212 – 265 g/mm, average 232 g/mm, higher than Emerald, similar to Optimus
o Berry Weight: 2.5 – 3.4 grams, average 3.0 grams, higher than Emerald
o Berry Diameter: 18.8 – 21.0 mm, average 19.9 mm, higher than Emerald
o Brix: 9.8 – 11.6, average 10.5, lower than Emerald, similar to Endura and Magnus
o Brix/Acid Ratio: 17.6 – 48.6, average 31.7, better than Emerald
o Fruit scar: large scar that can tear, requires careful hand harvesting
o Wax/bloom: high
o Fruit defects: large scar that can tear, requires careful hand harvesting
o Flavor Score 27.5 – reference Emerald (19.9), Kestrel (29.2)
o Aroma: none
Cultivars with overlapping timing of flowering: Emerald, Farthing, Keecrisp, Magnus, Optimus, Vireo
Other information: Late blooming but early and high fruit set with uniform ripening; good for the Florida market window when using hydrogen cyanamide. High yield when receiving adequate chilling.

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)
