Notice

The inbreeding coefficient refers to the workers of the planned colony. The inbreeding coefficient of the queen only depends on the mother colony and is 3.09 %.

Click on queen code shows pedigree, breeding values and inbreeding coefficients.

The total breeding values is calculated using the given weighting factors.

Only island and line mating stations with a registered 4a, subjected to breeding values estimation are displayed. For a full list of mating stations, see Allocation of mating stations.

The breeding record data is the responsibility of the state associations !

Use of genetic evaluation data for publications or commercial purposes is subject to permission by the Institute for Bee Research Hohen Neuendorf, Germany, Länderinstitut für Bienenkunde Hohen Neuendorf e.V.

The performance index is composed of the breeding value for honey yield, gentleness, calmness and swarming tendency in equal proportions.
