Abstract：Leymus mollis (Trin.)Hara (2n =28,NsNsXmXm)is one of the important genetic resources for wheat genetic improvement,which possesses a variety of excellent antiviral properties such as disease re-sistance and adversity tolerance.In this study,757 pairs of EST -SSR and STS primers were used to amplify the genomic DNA of L.mollis,Psathyrostachys huashanica and wheat varieties China Spring,Huixianhong, Yannong 15 and Jimai 22.And the specific molecular makers were screened for L.mollis,and were used to infer the chromosome -based group home.The results showed that 193 specific markers of L.mollis were screened out including 36 specific markers belonging to Ns group.The results have some practical values and significances to promoting the excellent gene of L.mollis transfer into wheat and breeding new Tritileymus germplasms.
