Development and adoption of Kernza—A perennial grain crop for sustainable agriculture

PLANTS, PEOPLE, PLANET, Volume 8, Issue 5, Page 1517-1532, September 2026.
Annual cereal grains account for ~50% of human food calories, but cultivation of these crops has resulted in major environmental and social issues worldwide. For nearly three decades, researchers have been breeding intermediate wheatgrass—a perennial cool‐season grass—to serve as the world's first commercial‐scale perennial grain crop to improve ...

Practical recommendations for researchers engaging in on‐farm research

Agronomy Journal, Volume 118, Issue 4, July/August 2026.
Abstract Though on‐farm research is crucial for addressing agricultural needs, it presents challenges that can derail projects if not addressed. Unlike small plot or greenhouse studies, on‐farm research evaluates tradeoffs in real‐world systems, offers access to diverse environments, and relies on farmer–researcher collaboration.

Alfalfa intercrop rarely limits productivity of intermediate wheatgrass across diverse edaphic and climate conditions

Frontiers in Sustainable Food Systems
Management practices that minimize soil disturbance, reduce inputs, and provide sustainability across a broad range of environmental conditions are needed to ensure productivity into the future.

Evaluation of disease resistance in intermediate wheatgrass and genome‐wide association for fusarium head blight‐related traits

Crop Science, Volume 66, Issue 4, July/August 2026.
Abstract Intermediate wheatgrass (IWG) [Thinopyrum intermedium (Host) Barkworth & D. R. Dewey] is a promising perennial grain candidate that The Land Institute has been directly domesticating since 2001. Grain from improved IWG can be sold under the trademark Kernza.

Genome‐wide association study identifies genomic regions under selection for domestication and agronomic traits in intermediate wheatgrass

The Plant Genome, Volume 19, Issue 2, June 2026.
Abstract Intermediate wheatgrass (IWG) (Thinopyrum intermedium, Kernza) is a perennial forage grass undergoing neo‐domestication as a grain crop. IWG provides numerous ecosystem services and has the potential to benefit rural communities as an alternative crop option with high market value.

Productivity of intermediate wheatgrass responds more to local soil and climate factors than fertility treatments in the first establishment year

Frontiers in Agronomy
The intensive cultivation practices of annual cereal crops have been causing unprecedented degradation of natural resources. Perennial crops such as intermediate wheatgrass (IWG) could provide numerous benefits to address these issues, but there is still

Genotype‐by‐environment interactions influence grain yields of intermediate wheatgrass

Agronomy Journal, Volume 118, Issue 3, May/June 2026.
Abstract Crop rotation with perennial grain crops, such as intermediate wheatgrass (IWG; Thinopyrum intermedium), marketed as Kernza, promotes agroecological intensification and environmental sustainability relative to annual cropping systems. To assess yield performance and adaptability of IWG breeding populations across diverse environments ...

Evaluating Kernza (Thinopyrum intermedium) as a Co‐Fermentation Feedstock for Bioethanol Production

Cereal Chemistry, Volume 103, Issue 3, Page 346-353, May/June 2026.
ABSTRACT Background Kernza (Thinopyrum intermedium), a perennial grain developed by the Land Institute, presents a promising alternative to conventional ethanol feedstocks due to its deep‐root systems, low fertilizer requirements, and carbon sequestration potential.

Comparative life cycle assessment of perennial and annual crop production: impact of farming systems and management practices

Frontiers in Sustainable Food Systems
The Intermediate Wheatgrass (IWG) Thinopyrum intermedium (Host) Barkworth & D.R. Dewey, marketed under the trade name Kernza® has been tested in France with a group of farmers since 2017. The Life Cycle Assessment (LCA) is a recognized methodology to

Temporal variability of soil health indicators under annual and perennial continuous living cover: Effects of annual weather and management

Soil Science Society of America Journal, Volume 90, Issue 2, March/April 2026.
Abstract Soil health indicators (SHIs) are used to detect changes in soil conditions in response to management. However, management effects must be disentangled from other factors influencing SHI variability. Specifically, how annual weather affects SHI remains poorly understood. To address this gap, we analyzed soil annually for 5 years at 64 sampling
