With assistance from BMELV and in close cooperation with the bee institutes in Kirchhain and Hohen Neuendorf, the Association of Breeding Tolerance has in recent years successfully developed selection methods for the selection of resistant bees (see final report on 03UM008, dated 12/12/2007). In the meantime, thresholds of infestation can be derived from experiments with untreated test colonies below which a therapeutic control of varroasis may be dispensed with. This opens up new avenues of subjecting untreated colonies to effective selection for vitality and to establish regional instances with a natural selection of their drone populations for disease tolerance. To this end, appropriate selection and propagation methods have to be combined with the use of a control approach based on threshold of damage. Based on results of the third-party funded project (03UM008), a concept is to be developed in cooperation with the Association of Breeding Tolerance that will optimise breeding progress in terms of disease resistance within the level of selection.Furthermore, practical ways of transferring breeding progress within the level of selection to the overall population as efficiently as possible are to be identified.New concepts of breeding value estimation for so-called "all or nothing" traits are to be adapted to the honey bee.
