Abstract - The variability of Apis mellifera mellifera in Eastern Europe was investigated with a morphometric analysis of 136 samples from Poland, Belarus and the Ukraine. Samples from the northern part of this area were unambiguously classified as A. m. mellifera, but the proportion of uncertain allocations increased towards the south, where some samples were classified as hybrids between A. m. mellifera and subspecies of the lineages C and O. In the Ukraine, one third of the samples were classified as A. m. mellifera, one third as A. m. macedonica, and one third as hybrids. Our results confirm earlier reports of a large hybrid zone in Poland and the Ukraine, but they unexpectedly also show a strong influence of the morphological O lineage. However, the true extension of this hybrid zone currently remains unknown. The bees of northeastern Belarus showed an extreme position on the border of the A. m. mellifera cluster, potentially indicating ecotypic variation within A. m. mellifera in the northeast of its range.
