Chloroplast DNA microsatellite analysis supports a polyphyletic origin for barley.

Five barley chloroplast DNA microsatellites (cpSSRs) were used to study genetic relationships among a set of 186 barley accessions-34 Hordeum vulgare ssp. spontaneum (HS accessions) from Morocco, Ethiopia, Cyprus, Crete, Libya, Iraq, Iran, Turkey, Afghanistan and Israel, 122 H. vulgare ssp.
