Péntek-Zakar, E., Jávor, A., & Kusza, S. (2014). Study the correlation of morphological and production traits of honey bee (Apis mellifera L.) (Review. Acta Agraria Debreceniensis, (57), 61–65. https://doi.org/10.34101/actaagrar/57/1961
There are several morphological differences among the honey bee subspecies, which proofs that they adapted different way to the environmental factors of the given area. Morphological observations are not the only way to separate subspecies, it is possible on their genetic speciality as well. The authors’s aim in this present study was to examine morphological characteristics of subspecies, furthermore looking for correlation between morphological parameters and honey yield. According to their results, among the most important parameters considered by Hungarian breeders, in the case of the native Apismelliferacarnica subspecies, the proboscis length could be the indirect tool for honey-productivity focused selection.
