Abstract: Meiotic chromosome pairing in three Hordeum x Elymus hybrids was analyzed. Hybrid plants of H. jubatum (HHHH) x E. canadensis (SSHH) showed a low level of chromosome pairing, but the observation of trivalents indicated the presence of three H genomes as expected. In the hybrid plants of H. parodii (HHHHHH) x E. canadensis (SSHH), the level of chromosome pairing was rather low, but up to three trivalents per pollen mother cell could be detected rather infrequently. In the progeny of H. parodii (HHHHHH) x E. scabriglumis (SSHH??), chromosome pairing was quite frequent with the occasional occurrence of quadrivalents and pentavalents. This can be explained if the genomic constitution of E. scabriglumis is assumed to be SSHHHH. © 1994 Kluwer Academic Publishers.
