U.S. Patent PP19,233
Southern Highbush Blueberry Variety
‘Scintilla’ has a vigorous and semi-upright in growth habit. Its survival under field conditions is medium to good. This survival implies acceptable levels of resistance to stem blight (Botryosphaeria dothidea) and root rot (Phytopthora cinnamomi), the principal pathogens that kill blueberries in Florida. The plant requires the standard commercial fungicide applications after harvest to retain leaves through autumn. The plant propagates readily from softwood cuttings and grows vigorously once established. ‘Scintilla’ is partially self-incompatible and requires cross pollination for full fruit set.
‘Scintilla’ produces only a medium number of fruit, but these are very large. The plant flowers earlier than Star and Windsor, and freeze protection may needed as early as January 20. The plant produces new vegetative growth early enough in the season to fully support berry development. Berry quality is high. The berry is large and has excellent color, scar, firmness and flavor. Berry clusters are loose and the berry can be harvested rapidly. Berries have been picked, packed, and shipped through a commercial packinghouse without problems.
Fruit Size: Large

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)
