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….
