The hexaploid bread wheat Triticum aestivum L. (AABBDD) is thought to have originated through one or more rare hybridization events between Aegilops tauschii (DD) and the tetraploid Emmer wheat T. turgidum subsp. dicoccon (AABB). The progenitor of the A genome of T. aestivum has generally been accepted to be T. urartu. The origin of the B genome, however, is controversial and still relatively unknown. Research has found the B genome in T. turgidum to be closely similar to the S genome in section Sitopsis of Aegilops L.; the Sitopsis diploid species were thus proposed as the probable maternal parent in …
