Abstract:The Leymus chinensis from different geographic populations were cultured in the campus and were used as materials in this research.Random amplified polymorphic DNA(RAPD) analysis was applied to these populations.Twenty random 10 mer primers yielded one hundred RAPD polymophic bands.Bands were scored (+/-) and un weighed pair group method with arithmetic mean(UPGMA) was used to generate dendrograms showing genetic relationships among the evaluated L.chinensis populations.Cluster analysis showed tha...
