摘要

Elymus sibiricus L.( Siberian wildrye) is a perennial, self‐pollinating and allotetraploid grass indigenous to Northern Asia, possessing the StH genome ( Dewey, 1974 ).In the subalpine meadows with less than 4000m altitude in Qinghai‐Tibet Plateau, E.sibiricus usually serves as an important forage species.Climate warming, loss of habit by deforestation and excessive gazing at high altitude pastures in the entire Qinghai‐Tibet Plateau region now begin to threaten its survival.In the present study, we employed ISSR markers to investigate the genetic structure of natural E.sibiricus populations from southeast of Qinghai‐Tibet Plateau.
