Sažetak
Morphomertical investigations were done on 732 honeybee workers from 44 colonies in the apiary of the Agricultural Institute of Slovenia. Fore- and hind-wing area, cubital index, lenght of hairs on targite 5, side surfaces of tibia, femur and metatarsus, and the lenght of tibial hiairs on the prepared hing legs were measured. The total side surfaces of hind-leg and wings were calculated. Investigated characteristics of bees were divided ino 2 groups: the first group included hind-leg and wing sizes while the second included hairs and index characteristics. The characteristics from the first group showed more expressed phenotypic and genetic correlation then the characteristics from the second group. All estimated heritabilities were large and significant. In an artificial selection of described properties of bees the selested traits are more or less successfully changed, the unselected characteristics are always a compromise between genetic relationships of the selected trait, and selection due to enviroment.
