Abstract
Hordeum murinum L. is a polyploid complex of thermophilic, annual, zoochoric grasses of Mediterranean–Irano-
Turanian origin that is commonly present in Europe. H. murinum complex includes three annual and most often
autogamous taxa: glaucum, leporinum and murinum. The variation of nuclear microsatellites, chloroplast microsatellites
and chloroplast SNP-based PCR-RFLP markers of H. murinum from Europe was analyzed in order to
investigate its migration. The chloroplast markers revealed three distinct haplotypes. Two of them are characteristic
of leporinum and murinum. A geographical pattern of haplotypes has been detected, however it does not correspond
to the known patterns of migration routes in the Holocene. Geographic distribution of genotypes defined
by nuclear microsatellites has shown a geographic trend that may link the migration of leporinum and murinum
with the spread of Neolithic agriculture in Europe. This study also confirms genetic distinction of glaucum, as
well as genetic uniformity of murinum and leporinum.
