Modeling carbon allocation strategies for high-yielding perennial crops
The Land Institute’s Lee DeHaan and Tim Crews co-authored a paper with colleagues from Loyola University that documents a model outlining the path to breeding high-yielding perennial crops that balance…
Perennial rice – An alternative to the ‘one-sow, one-harvest’ rice production: Benefits, challenges, and future prospects
With a high-yielding perennial rice variety moving onto landscapes in Asia and Africa, researchers from the Indian Institute of Rice Research (ICAR) and the International Rice Research Institute (IRRI) released…
Choice of companion legume influences lamb liveweight output and grain yields in a dual use perennial wheat/legume intercrop system
Research partners in Australia analyzed the role of perennial wheat, a crop in development at The Land Institute, as a dual-purpose grain and forage crop. The authors of this study…
Breeding Potential for Increasing Carbon Sequestration via Rhizomatous Grain Sorghum
Building on existing knowledge of perennial sorghum development through The Land Institute’s breeding program and considerations around the benefits of perennial grain agriculture through research from The Land Institute and…
Genetic variation and heritability of agronomic traits in a native perennial forage species from drylands: breeding potential of Festuca pallescens
A research cohort with scientists from the University of Wisconsin Madison and CONICET in Argentina assessed the potential of Festuca pallescens, a native, perennial forage grass species of Patagonia, for…
Soil microbial and plant biomass carbon allocation within perennial and annual grain cropping systems
Research collaborators from the University of Minnesota published a study indicating that perennial cropping systems with intermediate wheatgrass (Kernza) can sustain soil microbial activity and maintain higher root production than…
The microbiome of a perennial cereal differs from annual winter wheat only in the root endosphere
An international research cohort affiliated with universities and groups in Austria, Poland, Germany, France, Belgium, Sweden, Kenya, and the United Kingdom published a study looking at belowground biodiversity of microbes…
Flour composition, dough, and bread properties of intermediate wheatgrass (Thinopyrum intermedium) compared to annual wheat species
Researchers in Norway released findings around the properties of Kernza perennial grain in flour, dough, and bread compared to annual wheat using intermediate wheatgrass provided by Lee DeHaan, The Land…
Improving the Nutritional Profile of Intermediate Wheatgrass by Solid-State Fermentation with Aspergillus oryzae Strains
Research collaborators Takehiro Murai and George A. Annor from the University of Minnesota’s College of Food, Agricultural, and Natural Resource Sciences analyzed the use of Kernza in fermentation and the…
Introducing intermediate wheatgrass as a perennial grain crop into farming systems: insights into the decision-making process of pioneer farmers
Research collaborators at ISARA-Lyon in France conducted an analysis to better understand farmer needs related to Kernza production, including integration of the crop into existing systems, agronomic needs, and insights…
Metabolome fingerprinting reveals the presence of multiple nitrification inhibitors in biomass and root exudates of Thinopyrum intermedium
Nitrogen is an essential plant nutrient and is also linked to socioecological issues resulting from nitrogen-based fertilizer runoff from agricultural land to natural bodies of water and drinking water sources….
Selection for agronomic traits in intermediate wheatgrass increases responsiveness to arbuscular mycorrhizal fungi
A collaborative research paper between The Land Institute’s Lee DeHaan, Tim Crews, and colleagues at the Kansas Biological Survey and Center for Ecological Research showed that Kernza breeding at The…
