The Wheat Genome, including Synthetic Hexaploids

The diagram shows the natural evolution of the two most common hexaploid wheats, Spelt and Bread Wheat, also the laboratory hybridisation that created Synthetic Hexaploid Wheat (SHW).

The top and the right side of the diagram shows the evolution of Spelt and Bread Wheat.

On the left side of the diagram, Durum Wheat, a common tetraploid wheat, and a diploid Goat Grass are shown. These two have been artificially crossed by NIAB to create new Synthetic Hexaploid Wheats.

Using normal wheat crossing techniques, wheat breeders can transfer potentially useful genes from these SHWs into existing wheat varieties to widen the genetic diversity of modern wheat.
