Sažetak
In Germany 95.000 beekeepers maintain about 900.000 beehives. Most of them are organized in local beekeeping clubs which co-operate within Deutscher Imkerbund (DIB - the German beekeeper association). Starting more than 50 years ago there was a common approach to replace the local bee population by pure Carnica lines which were mainly imported from Austria and Slovenia. The breeding regulations of the DIB concern the selection procedure of breeder colonies, the maintenance of mating stations and the morphometrical analysis of the racial affiliation of all breeding colonies. More than 300 registered breeders and breeder associations are running about 200 mating stations and produce about 70.000 Carnica queens per year. Beside that there is a small group of mainly professional beekeepers who are selecting Buckfast bees. The primary selection focused on honey productivity, gentleness and low swarming tendency. Since about 10 years most test data are centrally evaluated by Prof Bienefeld at the bee institute in Hohen Neuendorf. The estimated breeding values of all test queens are available on the homepage of the institute ( www.honigbiene.de ) and are by now the general basis for the selection of breeder queens. Meanwhile, selection on Varroa tolerance became the main challenge of honey bee breeding in Germany. This complex task is coordinated by a nationwide breeder association called “ Arbeitsgemeinschaft Toleranzzucht” (AGT) which was founded in early 2003. So far, about 130 beekeeping operations with about 1500 test colonies are involved in a common selection program, supported by the Ferderal Ministry of Agriculture. All test queens of AGT are pure mated on mating stations or by artificial insemination. The breeders organize an anonymous exchange of test queens within local groups. At least 12 colonies are compared within one location. In addition to the primary selection criteria the beekeepers keep records on mite infestation and brood hygienic behaviour of their test colonies. From close to 8000 colonies the heritability for mite infestation and hygienic behaviour was estimated by 11% respective 18%. This gives a good opportunity for an effective breeding in large populations. At the end of the one year lasting test season (ending in July) the most promising colonies are identified and moved to isolated test stations. Their colony and mite population development during autumn and winter will be carefully studied without any use of Varroa treatments. This viability test will be complemented by investigations on the mite reproductive behaviour and the virus infestation level of the colonies. The aim of the selection program is to identify highly productive and gentle breeder colonies which can survive long lasting with only one single winter treatment.
