Forage harvest management impacts “Kernza” intermediate wheatgrass productivity across North America
Research into the productivity of Kernza as a forage and grain crop examines the plant’s profitability associated with its dual-purpose nature, the mechanisms driving increased productivity of the crop, and…
Nitrate leaching losses and the fate of 15N fertilizer in perennial intermediate wheatgrass and annual wheat — A field study
Recent research in ecology illustrates the advantage that perennial grains like Kernza (intermediate wheatgrass) possess in reducing nitrate leaching when compared to popular annual grain crops like wheat, as the…
Agronomic assessment of two populations of intermediate wheatgrass-Kernza® (Thinopyrum intermedium) in temperate South America
Recent research with Intermediate Wheatgrass in Uruguay highlights for the first time the agronomic performance of Kernza in a low-latitude region with mild winters, which will be vital towards efforts…
Breeding Intermediate Wheatgrass for Grain Production
This research paper details the improvement of breeding efforts with intermediate wheatgrass resulting from advances in molecular technologies, allowing scientists to focus on producing desirable agronomic traits to create an…
Policy pathways for perennial agriculture
Recent research highlights the policy mechanisms and market developments that are necessary to catalyze a shift toward perennial agriculture systems that provide more substantial ecosystem services and greater climate resilience…
Perennials as Future Grain Crops: Opportunities and Challenges
New research published in parternship by Carlsberg Group Future Crops, The Land Institute, University of Copenhagen, Carlsberg Foundation, Swedish University of Agricultural Sciences in Uppsala, Innovation Fund Denmark, Lund University in…
Development of whole‐genome prediction models to increase the rate of genetic gain in intermediate wheatgrass (Thinopyrum intermedium) breeding
Abstract The development of perennial grain crops is driven by the vision of simultaneous food production and enhanced ecosystem services. Typically, perennial crops like intermediate wheatgrass (IWG)[Thinopyrum intermedium (Host) Barkworth…
Nested association mapping reveals the genetic architecture of spike emergence and anthesis timing in intermediate wheatgrass
Abstract Intermediate wheatgrass (Thinopyrum intermedium) is an outcrossing, cool season grass species currently undergoing direct domestication as a perennial grain crop. Though many traits are selection targets, understanding the genetic…
Genomic Prediction Enables Rapid Selection of High-Performing Genets in an Intermediate Wheatgrass Breeding Program
Abstract In an era of constrained and depleted natural resources, perennial grains could provide sustainable food production along with beneficial ecosystem services like reduced erosion and increased atmospheric carbon capture….
Post-Harvest Management Practices Impact on Light Penetration and Kernza Intermediate Wheatgrass Yield Components
Abstract Kernza intermediate wheatgrass (Thinopyrum intermedium) is the first commercially developed perennial grain crop in North America, with multiple environmental and economic benefits. One of the major challenges for adoption…
Sequenced-Based Paternity Analysis to Improve Breeding and Identify Self-Incompatibility Loci in Intermediate Wheatgrass (Thinopyrum intermedium)
Abstract In outcrossing species such as intermediate wheatgrass (IWG, Thinopyrum intermedium), polycrossing is often used to generate novel recombinants through each cycle of selection, but it cannot track pollen-parent pedigrees…
Carbon and water relations in perennial Kernza (Thinopyrum intermedium): An overview
Abstract Perennial crops have been proposed as a more sustainable alternative to annual crops, because they have extended growing seasons, continuous ground cover, reduced nutrient leakage, and sequester more carbon…
