Tricticum aestivum |
Other names: Bread Wheat
|
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.

Other forms of common wheat
Compact wheats (e.g. Club Wheat Triticum compactum, but in India T. sphaerococcum) are closely related to Common Wheat, but have a much more compact ear. Their shorter rachis segments lead to spikelets packed closer together. Compact wheats are often regarded as subspecies rather than species in their own right (thus T. aestivum subsp. compactum).
