Hybrids were obtained by crossing Thinopyrum scirpeum (4x) and T. junceum (6x) onto Triticum aestivum cv, ‘Chinese Spring’. An average meiotic pairing of 24.44 I + 5.07 II + 0.14 III in the ‘Chinese Spring’× T. scirpeum hybrid (ABDE 1 E 2 ) is attributed to two similar genomes from T. scirpeum (E 1 E 2 E 3 E 4 ). An average meiotic chromosome pairing in the other hybrid (ABDJ 1 J 2 E 3 ) was 31.70 I + 3.80 II + 0.90 III and is attributed to autosyndetic pairing between the three genomes of T. junceum.
