Application. Genotyping at DNA microsatellite loci identified pollen donors of a large sample
of acorns and saplings in one stand of bur oak. The data were used to test if several character-
istics of pollen donors were correlated with reproductive success. Male reproductive success
could not be completely explained by any factor tested, including distance from maternal tree,
direction of tree relative to maternal tree, size of tree, or genetic relatedness to maternal tree.
Managers of seed orchards should consider that pollination contamination from distant sources
may be extremely common and may not necessarily be confined to trees at the edge of the
