San Joaquin FLX-1

U.S. Patent PP19,342
Southern Highbush Blueberry Variety

Description

FLX-1’ is a southern highbush blueberry clone distinguished by its low chilling requirement, its vigorous, upright bush and by its very firm, sweet berries. Through multiple field trials, it has been determined that ‘FLX-1’ is best suited for commercialization in desert or Mediterranean climates.

In Florida, ‘FLX-1’ is excessively susceptible to stem blight (Botryosphaeria dothidea), which kills plants after two or three years in the field. ‘FLX-1’ also does not receive enough chill hours in the state of Florida to properly leaf in the Spring.

In field trials conducted in the proper climate, ‘FLX-1’ produces berries of very high quality, yields well, and exhibits a very desirable upright growth habit.

  • Fruit Size: Large

  • Chill Requirement: 400-500 hours

  • Growth Habit: Upright

  • First Harvest: Around April 20 near Gainesville, FL

Performance 2018-2019 Season

Graph Details

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. 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
