Germplasm evaluation trials were established jointly by Chinese and Amrican scientists in central-northern Inner Mongolia and in northem intermountain west USA. Entries included Asian and North Amrican grasses, legumes and shrubs for restoration of steppe, saline lowland and open woodland sites. The plantingr were evaluated for percent stand, vigor, foliage height, forage vield, forage unifor-mity, ground cover and spread ability ect. Results of the Chinese plots show: Chinese grasses of Agropy-ron, and legumes of Melissitus, Astragalus and Lespedeza outformed American entries on steppe and desert-steppe sites. Chinese collections of Leymus chinensis and American cultivare of Pascopyrum smithii were similar on stand and forage yield, but Chinese collections were relatively stabler on steppe site. Amrican saline-tolerant cultivare rated the best stands and had the highest yields on saline and mesic sites. on desert-steppe and sandy site, Chinese shrub species of Caragana established stably and the subshrubs of Hedysarum spreaded well once it established.
