Abstract - The heritability of colour patterns of honeybee (Apis mellifera) queens, workers and drones, the offspring of the 10th generation of 20 queen families were studied. The queen offspring of the 11th generation of 10 families were also examined. Colour classifications were made for queens, workers and drones. The heritability of the colour of queens was 0.21 to 0.23; of workers 0.32, and drones 0.39, all significantly different from zero. It may be possible to breed honeybee families for distinctive colour within closed population breeding with natural mating.
