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…
Process-based analysis of Thinopyrum intermedium phenological development highlights the importance of dual induction for reproductive growth and agronomic performance
Abstract Intermediate wheatgrass (Thinopyrum intermedium (Host) Barkworth & D.R. Dewey) is being developed for use as a new perennial grain crop through breeding and agronomic research. However, progress has been hampered…
Development of First Linkage Map for Silphium integrifolium (Asteraceae) Enables Identification of Sporophytic Self-Incompatibility Locus
SUMMARY Silphium integrifolium (Asteraceae) has been identified as a candidate for domestication as a perennial oilseed crop and has a sporophytic self-incompatibility system—the genetic basis of which is not well understood…
A Social Perennial Vision: Transdisciplinary Inquiry for the Future of Diverse, Perennial Grain Agriculture
Societal Impact Statement Plant scientists around the planet are working to develop new perennial grains and learn how to grow them in diverse agroecosystems. Perennial grain agriculture could accomplish long‐term…
Silflower Seed and Biomass Responses to Plant Density and Nitrogen Fertilization
Silflower (Silphium integrifolium Michx.) is a potential perennial oilseed crop that can provide ecosystem services; however, its seed, oil, and biomass yield potential are unknown. Our objectives were to determine the…
Detection of Quantitative Trait Loci Regulating Seed Yield Potential in Two Interspecific S. bicolor2 X S. halepense Subpopulations
Abstract Perennial sorghum cropping offers substantial economic and ecological benefits, conserving fuel, water, and soil. To be perennial in temperate climates, a sorghum plant must over-winter and produce new growth…
Transmission Genetics of a Sorghum bicolor × S. halepense Backcross Populations
Despite a “ploidy barrier,” interspecific crosses to wild and/or cultivated sorghum (Sorghum bicolor, 2n = 2x = 20) may have aided the spread across six continents of Sorghum halepense, also exemplifying…
Who is We?
Abstract Glaring inequality, both between and within societies, makes it difficult to talk about ‘we’ – a collective human project of understanding and responding to multiple, cascading ecological crises. Assigning…
Patterns of genetic variation in a prairie wildflower, Silphium integrifolium, suggest a non-prairie origin and locally adaptive variation
PREMISE: Understanding the relationship between genetic structure and geography provides information about a species’ history and can be used for breeding and conservation goals. The North American prairie is interesting…
Balancing Forage Production, Seed Yield, and Pest Management in the Perennial Sunflower Silphium integrifolium (Asteraceae)
Abstract The perennial sunflower Silphium integrifolium Michx. (Asteraceae), also known as silflower, is a prospective dual-purpose forage plus grain crop. Pre-flowering biomass harvest for animal feed and the subsequent delay…
