Because of the differences of ecologic environment there are abundant cold tolerant , anti‐alkalitolerant , drought and barren tolerant species and biotypes . Identifying germplasm resources and their scientific utilization isnecessary not only for the development of animal husbandry , but also for control of the environment .Forage germplasm resource composition The continuity of the Daxinganling , Xiaoxinganling , and Zhangguangcailing mountains ,whose peaks rise and fall along the skyline are natural woodland and these mountain ranges resemble a horse摧s hoof thatencircles the Songnen plain , with interleaving forest and grasslands , temperate zones and cold temperate zones . Therefore ,there are three types of plant flora in this area : Mongolia , Changbai and Xingan .In this complicated area , about ２１００ speciesare distributed , and about １０００ of them have an economic value According to investigations there were １１ families , ２２７ genera ,and ７９６ species . .Utilization and researching of germplasm resourcesDomestication of wild species Leymus chienesise ( T rin .) Tzvel were domesticated in the １９６０s and Melissitus ruthenicus C .W .Chang in the １９７０摧s . They were registered by the Chinese Herbage Cultivar Registration in １９８８ .Native species and the new species Medicago sativ a L in Zhaodong adopted a protection and grow measure , becoming with coldtolerant , drought tolerant for the native species registered in １９８９[ １ ] .The diploid Melissitus ruthenicuse C .W .Chang crossing with traploid Medicago sativ a L cv . zhaodong which was successfullybred [ ３ ] using of the artificial inducing method with the ６０Co‐rwhich increased seed matur of A straglus adsurgens Pall inHeilongjiang .Introduced varieties The best foreign Medicago species is Medicago varia Martin .cv .Rambler , and the better domesticMedicago species are the Caoyuan No １ and No ２ , the Gongnong No１ and ２ .
