| Abstract: | Hybrids were obtained by crossing Thinopyrum scirpeum (4x) and T. junceum (6x) onto Triticum aestivum cv, ‘Chinese Spring’. An average meiotic pairing of 24.44I+ 5.07II+ 0.14IIIin the ‘Chinese Spring’×T. scirpeum hybrid (ABDE1E2) is attributed to two similar genomes from T. scirpeum (E1E2E3E4). An average meiotic chromosome pairing in the other hybrid (ABDJ1J2E3) was 31.70I+ 3.80II+ 0.90III and is attributed to autosyndetic pairing between the three genomes of T. junceum. |
