Color code and Abbreviations

Queen without information : B314(GEK)
Queens from one strain, but mated by drones from another strain .
Their population and daughters (and drones of them) are F1 crossed.
Queen and Drones have the same ancestors: combination to increase or stabilize some characteristics
Queen and/or Drones have unknown exact origin : that makes unable to find their real status.
Queen and Drones result of a cross between two different lines : interesting to increase their resistance and qualities.
