In spite of high biodiversity within the honeybee species Apis melliferaL., only one geographical race, the dark-colored forest honeybee A. m. mellifera, is uniquely adapted to severe environmental conditions of Eurasian forest and forest-steppe zones. Within the vast range of this race, only single isolates remain, where the dark forest honeybee is purebred. The Bashkir population is supposed to be one of these isolates. Molecular-genetic assessment of the state of the gene pool of this population revealed that southern honeybee races were introduced into the Bashkortostan Republic with great intensity, which was above the assimilation capacity of the population. The main part of the former range of the Bashkir population represents a hybrid zone with approximately equal ratio between gene pools of local and introduced honeybees. Our studies provide the possibility to single out one extant reserve of A. m. mellifera, Burzyanskii raion, in which the proportion of local bees in the gene pool is 0.98.
