| Abstract: | The DNA genetic diversity of 40 accessions of genus Leymus was analyzed by random amplified polymorphic DNA (RAPD) markers. A total of 352 products were amplified by 34 10-mer arbitrary
primers, among which 337 products (95.74 %) were found to be polymorphic. 5–14 polymorphic bands were amplified by each polymorphic
primer, with an average of 9.91 bands. The data of 352 RAPD bands were used to generate Jaccard’s similarity coefficients
and to construct a dendrogram by means of UPGMA. Great genetic diversity in genus Leymus was observed, the genetic diversity among the different species more abundant than that of the different accessions, and
the different accessions in a species or the species from the same areas were clustered together. |
