Inner Mongolia is rich in forage germplasm resources of Gramineae, which has many wild ancestor and relative species of cultivated forage. And there are also some rare forage distributed only in Mongolian plateau. These forage germplasm resources contain abundant genetic diversity, which is a rare treasure of forage breeding. We should attach great importance to the research on forage germplasm resources and make full use of it.There are 23 species of wild ancestor of Gramineae cultivated forage in Inner Mongolia. They are : Agropyron cristatum (L.) Gaertn., A. mongolicum Keng, A. desertorum (Fisch.) Schult., A. fragile (Roth) Candargy, Elymus sibiricus L., E. nutans Griseb., E. dahuricus Turcz., Alopecurus pratensis L., A. arundinaceus Poir., Festuca rubra L., F. ovina L., Bromus inermis Leyss., Agrostis gigantea Roth, Roegneria ciliaris(Trin.)Nevski, Bothriochloa ischaemum(L.)Keng, Echinochloa crusgalli (L.) Beauv., Poa pratensis L., Phalaris arundinacea L., Hordeum brevisubulatum (Trin.) Link, Leymus chinensis (Trin.) Tzvel., Puccinellia tenuiflora (Griseb.) Scribn. et Merr., Psathyrostachys juncea (Fisch.) Nevski, Elytrigia repens (Linn.) Nevski.Inner Mongolia is also rich in the relative species of Gramineae cultivated forage. This article cites 35 main close relative species of 14 Gramineae cultivated forage.Because of the Mongolian plateau’s natural and geographical environment, there formed 15 species of peculiar rare Gramineae forage in the Mongolian plateau and its surrounding regions. They are : Agropyron mongolicum Keng, Psammochloa villosa (Trin.) Bor, Stipa klemenzii Roshev., S. mongolorum Tzvel., Poa argunensis Roshev., P. transbaicalica Roshev
