Representative gels of PCR amplification of 12 Triticeae species. a Amplification of L. racemosus by its genome-specific marker b Amplification of Leymus species by a Leymus-specific marker. c Specific amplification of Leymus species and Psathyrostachys huashanica (a species of Leymus N-genome progenitor genus). d Amplification of all the species by a conserved marker sequence, showing size polymorphism between the species
