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)
