Abstract: Ten species of Elymus (Poaceae: Triticeae) were analyzed using random ampli- lied polymorphic DNA (RAPD) markers.  Thirty-four decamer oligonucleotide random primers from Opron Technologies were used for polymorphic selection. 25 (73.53%) pro- duced polymorphic products. A total of 136 bands amplified from 16 primers were selected for RAPD analyses. The data were used to generate Nei's similarity coefficients and to con- struct a dendrogram using UPGMA in NTSYS programs. The result showed that: (1) Three tetraploid species, E. sibiricus L., E. caninus (L.) L. and E. lanceolatus (Scrib- ner et Smith) Gould, were clustered in one group, while seven hexaploid species, E. nu- tans Griseb., E. dahuricusTurcz., E. brachyaristatus A Löve, E. submuticus (Keng) Keng f., E. tangutorum (Nevski)Hand.-Mazz., E. excelsus Turcz. and E. cylindricus (Franch) Honda, were clustered in another group. The relationship between the tetraploid and the hexaploid species was remote; (2) E. caninus was closely related to E. sibiricus. This result supported that Roegneria canina (L.) Nevski was treated as Elymus caninus; (3) E . nutans was closely related to E. dahuricus ; (4) E.brachyaristatus and E.sub- muticus were morphologically similar and sympatric in distribution, but there were certain differences between them in the nucleotide sequences. Both of them were related to E. nu- tans and E. duhuricus; (5) E. excelsus was closely related to E. cylindricus, and they were clustered with E. tangutorum; (6) RAPD results are basically comparable with those obtained from studies on morphology and cytology. It is a useful supplementary method forassessing the genetic relationships among Elymus species.Decontaminated thianthrene disproportion.
