Maintaining grain yields of the perennial cereal intermediate wheatgrass in monoculture v. bi-culture with alfalfa in the Upper Midwestern USA
Intermediate wheatgrass (Thinopyrum intermedium; IWG) is a perennial cereal crop undergoing development for grain production; however, grain yield declines of >75% are often observed after year 2 of the perennial…
Transforming human life on our home planet, perennially
The development of agriculture is one of the key fault lines in human history, the starting point for the human project of dominating the planet. As the catastrophic consequences of…
Strategies, Advances, and Challenges in Breeding Perennial Grain Crops
Abstract: The development of new perennial crop species is gaining momentum as a promising approach to change the fundamental nature of ecosystem processes in agriculture. The ecological argument for perennial…
Nitrogen use efficiency is regulated by interacting proteins relevant to development in wheat
Summary: Wheat (Triticum aestivum) has low nitrogen use efficiency (NUE). The genetic mechanisms controlling NUE are unknown. Positional cloning of a major quantitative trait locus for N-related agronomic traits showed…
Managing Crops for Climate Change Can Also Manage Pests
The impacts of climate change are already being felt by farmers in many parts of the world. As such, it is important for us to determine which strategies may help…
Development and Evolution of an Intermediate Wheatgrass Domestication Program
Abstract: Ecological intensification of agriculture is a proposed strategy to enhance the production of food while expanding ecosystem services and reducing inputs. Perennial plants that are directly harvested for human…
Mapping of leaf rust resistance genes and molecular characterization of the 2NS/2AS translocation in the wheat cultivar Jagger
Abstract: Winter wheat cultivar ‘Jagger’ was recently found to have an alien chromosomal segment 2NS that has Lr37, a gene conferring resistance against leaf rust caused by Puccinia triticina. The objective of…
The Performance of Early-Generation Perennial Winter Cereals at 21 Sites across Four Continents
Abstract: A network of 21 experiments was established across nine countries on four continents and spanning both hemispheres, to evaluate the relative performance of early generation perennial cereal material derived…
Managing for Multifunctionality in Perennial Grain Crops
Abstract: Plant breeders are increasing yields and improving agronomic traits in several perennial grain crops, the first of which is now being incorporated into commercial food products. Integration strategies and management…
Perennial Grain Legume Domestication Phase I: Criteria for Candidate Species Selection
Abstract: Annual cereal and legume grain production is dependent on inorganic nitrogen (N) and other fertilizers inputs to resupply nutrients lost as harvested grain, via soil erosion/runoff, and by other natural…
Effect of Puccinia silphii on Yield Components and Leaf Physiology in Silphium integrifolium: Lessons for the Domestication of a Perennial Oilseed Crop
Abstract: New crops with greater capacity for delivering ecosystem services are needed to increase agricultural sustainability. However, even in these crops, seed yield is usually the main criteria for grain domestication….
Progress and Bottlenecks in the Early Domestication of the Perennial Oilseed Silphium integrifolium, a Sunflower Substitute
Abstract: Silflower (Silphium integrifolium Michx.) is in the early stages of domestication as a perennial version of oilseed sunflower, its close relative. Grain crops with deep perennial root systems will provide…
