Evolution
Bread wheat is an allohexaploid (an allopolyploid with six sets of chromosomes, two sets from each of three different species). Free-threshing wheat is closely related to spelt. As with spelt, genes contributed from goatgrass (Aegilops tauschii) give bread wheat greater cold hardiness than most wheats, and it is cultivated throughout the world's temperate regions.
