Tetraploid wheat landraces in the Mediterranean basin: taxonomy, evolution and genetic diversity.

The geographic distribution of genetic diversity and the population structure of tetraploid wheat landraces in the Mediterranean basin has received relatively little attention. This is complicated by the lack of consensus concerning the taxonomy of tetraploid wheats and by unresolved questions regar...
