Abstract
To investigate the genome origin and phylogenetic relationships of Elymus villosus, three single-copy nuclear gene (Acc1, Pgk1 and DMC1) and chloroplast trnL-F gene sequences of two accessions of E. villosus were analyzed with those of eighteen allotetraploids (StH, StY, StP and StEe genomes) and thirty-five diploid taxa representing eighteen basic genomes in Triticeae. The results revealed that: (1) the genomic constitution of E. villosus is StH as Elymus; (2) North America Pseudoroegneria species served as the maternal donor during the allotetraploid speciation of E. villosus; (3) E. villosus is closely related to North America Elymus species; (4) it is reasonable to recognize the E. villosus as Elymus L. sensu stricto.
