Hybrids of bread wheat (Triticum aestivum) with Thinopyrum scirpeum (4x) and Thinopyrum junceum (6x)

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+ 0.14III in 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
