The origin of bread wheat. Bread wheat (Triticum aestivum), is an allo-hexaploid originated via multiple hybridizations. The most accepted hypothesis of its origin is based on the hybridization of Triticum urartu (AA; 2× = 14) and Aegilops speltoides (BB; 2× = 14), resulting in tetraploid pasta wheat (AABB; 4× = 28). At the next step, hybridization of the tetraploid wheat with Aegilops tauschii (DD; 2× = 14) resulted in the emergence of the hexaploid bread wheat (AABBDD; 6× = 42).
