A Timeline of Perennial Wheat and Intermediate Wheatgrass Research and Breeding.

We’ve created a timeline detailing the history of Thinopyrum intermedium (Intermediate wheatgrass) to show how the trademarking of Kernza® grain came about.   We highlight some of the important agronomic research made by various institutions to continually develop and improve intermediate wheatgrass as a perennial grain. This timeline also features key progress made in perennial wheat research and breeding.
