In order to find out the distribution of germplasm resources in the Tibet autonomous region and to enrich the germplasm,The investigation and collection of germplasm resources of Bromus in south-central Tibet Autonomous Region were initially carried out. The survey collected 9 species of Bromus including Bromus inermis, Bromus japonicus, Bromus tectorum, Bromus sinensis, Bromus gracillimus, Bromus staintonii, Bromus pectinatus, Bromus racemosus and Bromus hodeaceus a total of 71 73 copies. Among them, there are three four new records unrecorded in "Flora of Tibet", namely, Bromus japonicas, Bromus pectinatus, Bromus racemosus and Bromus hodeaceus. Compared with the original national germplasm resources at three libraries collected in Tibet, which is 1 species of 1 copies, which greatly enriched the national forage germplasm resource pool; enlarged the existing recorded species distribution area; It laid the data and material basis for further study of wild forage resources in Tibet autonomous region, and provided raw materials for further domestication and breeding of wild pasture in Qinghai Tibet Plateau.
