Alfalfa ( Medicago sativa L.) is a widely planted perennial forage legume grown throughout temperate and dry subtropical regions in the world. Long breeding cycles limit genetic improvement of alfalfa, particularly for complex traits such as biomass yield. Genomic selection (GS), based on predicted values obtained using genome‐wide molecular markers, could enhance efficiency terms gain per unit time cost. In this study, we genotyped tetraploid alfalfa plants that had previously been...
Abstract Hemp ( Cannabis sativa L.) is an emerging dioecious crop grown primarily for grain, fiber, and cannabinoids. There good evidence medicinal benefits of the most abundant cannabinoid in hemp, cannabidiol (CBD). For CBD production, female plants producing but not tetrahydrocannabinol (THC) are desired. We developed validated high‐throughput PACE (PCR Allele Competitive Extension) assays C. plant sex chemotype. The assay was across a wide range germplasm resolved male from monoecious...
Abstract Given the dramatic rise in high‐cannabinoid hemp ( Cannabis sativa L.) production last decade, there is an increasingly urgent need to characterize available germplasm and develop knowledge accelerate breeding of uniform stable cultivars. Despite persistent cultivation cultivars for grain or fiber around world, diversity genetic underpinning key traits are poorly understood. For 30 high‐cannabidiol replicated on two field sites, we sought evaluate yield, agronomic performance,...

No obvious was found our population, which could be due the...
The Regional Feedstock Partnership is a collaborative effort between the Sun Grant Initiative (through Land Universities), US Department of Energy, and Agriculture. One segment this partnership field-scale evaluation switchgrass (Panicum virgatum L.) in diverse sites across USA. Switchgrass was planted (11.2 kg PLS ha−1) replicated plots New York, Oklahoma, South Dakota, Virginia 2008 Iowa 2009. Adapted cultivars were selected for each location baseline soil samples collected before...
Abstract Switchgrass ( Panicum virgatum L.) has been the principal perennial herbaceous crop investigated for bioenergy production in North America given its high potential, relatively low input requirements, and potential suitability use on marginal lands. Few large trials have determined switchgrass yields at field scale lands, including analysis of costs. Thus, a field‐scale study was conducted to develop realistic yield cost estimates diverse regions USA . Objectives included measuring...
