Genetic history of European barley

Nice new information on the genetics of Hordeum vulgare that may help to understand the Neolithic in Europe:

These landraces are what was being grown traditionally before the advent of 20th century industrial homogenization of crops. The authors discern nine populations using STRUCTURE, however, as we can see in fig. 4 below, some of these populations are paraphyletic.

identified at K = 9. (Note: Pop3 is restricted to the Alps, barely visible)

the microsatellite genotypes of all accessions

The authors inform us in greater detail of the characteristics of the various populations within the paper's "origins of the populations" section.
