- Traditional varieties of Blueberries were produced in geographic areas where chill hours (cold hours) were available.
- In recent years, blueberry production has extended to areas close to the Equator, where there is limited or no chill hours at all.
- This has been possible with varieties that are capable of adapting to these new conditions and with new genetics especially dedicated to this type of climate conditions.
- This expansion has made blueberries available 52 weeks in different markets.
