First food-grade intermediate wheatgrass released
In an article recently published in the Journal of Plant Registrations , a publication of the Crop Science Society of America, University of Minnesota researchers report the release of the first commercially available intermediate wheatgrass (IWG) cultivar. IWG is a cool-season perennial grain crop domesticated primarily for food use while maintaining the ecological benefits it offers.
The cultivar, named 'MN-Clearwater,' produces 696 kg ha-1 (621 lb ac-1) of grain on average with the first two years; it produces its highest grain yields under Minnesota conditions. It is relatively short at 113 cm and has minimal lodging with trace disease levels. MN-Clearwater is expected to perform well in US Upper Midwest, southern regions of Canada, and the US Northeast.
As the first IWG cultivar released for sale under the Kernza® trade name, we expect MN-Clearwater to be a cornerstone resource for the IWG research community as well as for interested growers, food processors, and commercial partners.
