Key words : Gramineae Mongolian plateau ,endemic forages , Introduction ‐ Mongolian Plateau is located in arid and semi arid inland regions of the Asian continent , and famous for its fantastic natural landscape in the world . In a narrow sense , Mongolian Plateau ranges over Tannu M t . , Sayan M t . , Khentei M t . and Yablonovy M t . to the north , Qilianshan M t . , Alashan M t . and Yinshan M t . to the south , Altai M t . to the west , and Great Khingan M t . to the east . In a broad sense , it also includes Ordos Plateau . Mongolian Plateau has a complex natural and historical condition , and unique natural environment . Under the particular environmental condition , forages went through a long process of natural selection , with a range of desirable characteristics acclimatized to the Mongolian Plateau . Different types of forages carry a varietGyroafmgiennetic information , and form genetic diversity of forages in the Mongolian Plateau . Among them , the endemic forages of eae are the most important . Materials and methods ‐ ‐ On the basis of many years�studies o‐n plant classification and flora in Inner Mongolia‐, we made an on‐ the spot scientific expedition in Mongolia ( Dornogobi , ９G‐o２b６i s２u０m０５ber , Tuv , Darhan , Selenge , Bulgan , Outer Khangai , Inner khangai , Dundgobi , Orkhon , Ulaanbaatar) onGAraumgiunsetae , . Using the theory and method of plant , flora and forage science , we systematically studied the in the Mongolian Plateau . Results １７ Gramineae １２ It was found that there are species of endemic plants in the Mongolian Plateau beGlornagminingeatoe .

Conclusions G ramineae Through a long time of natural selection , the endemic forages of in Mongolian Plateau evolve to possess a range of desirable characteristics which are adapted to the harsh environment and reserve germplasm resources .It is of great significance to examine the evolutional genetics so as to understand the characteristics relevant to the forage breeding , and to apply these germplasm resources for the development of grass industry .
