• To investigate the phylogenetic relationships among species with awnless lemmas in Roegneria and their related diploid genera, the possible genomic constitution and genome donor of species with awnless lemmas in Roegneria, phylogenetic analyses of disrupted meiotic cDNA (DMC1) sequences were investigated in this study. The results showed that: (1) Roegneria alashanica-1 grouped with the Y-type sequences and Roegneria alashanica-2 grouped with the St-type sequences, confirming that Roegneria alashanica has the StY genomes. (2) Roegneria grandis-1 grouped with the Y-type sequences and Roegneria grandis-2 grouped with the St-type sequences, confirming that Roegneria grandis has the StgY genomes, where the St genome from R. grandis is different from the St genome but is homologous with the Y genome. (3) Two Roegneria elytrigioides sequences grouped with the St-type sequences, confirming that Roegneria elytrigioides has the St1St2 genomes and should therefore be classified as Pseudoroegneria elytrigioides. (4) We prefer the suggestion that the Y genome is closely related to the St genome, however, the data do not certify that the St and Y genomes have the same origin. •DMC1 was used to analyze to phylogenetic relationships of Roegneria species and their closely related species.•DMC1 was used to analyze maternal donor of Roegneria.•Use of DMC1 sequences in systematic and evolutionary studies of Roegneria.
