    Markedly different? (Don't have Dadant, a sorry state of affairs for one who pretended to be knowledgeable on bee matters .... )

    The following refers to increased honey production according to Ruttner

    Mellifera * Carnica 31 %
    Carnica * mellifera 33% (very aggressive)

    Ligustica * carnica 70% (aggresive)
    carnica * Ligustica 10% (gentle)

    He says : In crossbreeding not all the strains of two races show the same beneficial heterosis effect. The specific combining ability has to be tested in every single case. Another difficulty in crossbreeding lies in the development of unfavourabable characteristics in many cases. The extraordinary vigourous and hardy hybrids (mellifera * carnica) are very aggressive.
