Cold stress (CS) affects the survivability, geographical distribution, and yield stability of crops. Suitable management agronomic practices can minimize crop losses associated with cooler environments. However, alone can't support plants adequately to withstand harsh cold. Therefore, exploring cold stress-responsive factors such as genetic, epigenetic, physiological, cellular is crucial. This report discusses on effect, signal perception, transduction, gene expression, molecular phenomena...
Abstract The lowland ecotype of switchgrass has generated considerable interest because its higher biomass yield and late flowering characteristics compared to the upland ecotype. However, ecotypes planted in northern latitudes exhibit very low winter survival. Implementation genomic selection could potentially enhance breeding for survival by reducing generation time while eliminating dependence on weather. objectives this study were assess potential combining multiple populations training...
Low-temperature related abiotic stress is an important factor affecting winter survival in lowland switchgrass when grown northern latitudes the United States. A better understanding of genetic architecture freezing tolerance will aid development cultivars with improved survival. The objectives this study were to conduct a assessment, generate map using single nucleotide polymorphism (SNP) markers, and identify QTL (quantitative trait loci) associated × upland population. pseudo-F2 mapping...
Abstract Over the last decade, there has been a renewed interest in sainfoin ( Onobrychis viciifolia Scop.), particularly among western Canadian forage and beef‐cattle producers. A major trigger availability of new cultivars with improved compatibility alfalfa Medicago sativa ). These binary mixture significantly reduced incidence pasture bloat grazing animals, potentially saving an estimated CAD 300–500 million worldwide, largely by eliminating direct animal losses expenses associated...
Drought stress is one of the major abiotic factors affecting forage production; thus, it essential to obtain a better understanding how responds drought. The main objective this study was evaluate legume-grass mixed stands respond drought when compared grass monoculture. A greenhouse pot experiment conducted using red clover (Trifolium pratense L.)—timothy (Phleum L.) stand and timothy monoculture stand, where plants were subjected severe (20% field capacity—FC), moderate (40% FC),...
Rising emissions of anthropogenic greenhouse gases such as carbon dioxide (CO2), nitrous oxide (N2O) and methane (CH4) are a key driver climate change, which is predicted to have myriad detrimental consequences in coming years if not kept check. Given the potency CH4 terms trapping heat atmosphere short term, well fact that ruminant production currently contributes approximately 30% emissions, there an impetus substantially decrease generation ruminant-derived CH4. While various strategies...
<title>Abstract</title> Plant genebanks contain large numbers of accessions that likely harbor useful alleles or genes absent in commercial plant breeding programs. Broadening the genetic base alfalfa germplasm with these variations can be accomplished by screening extensive diversity collections and enabling maximal recombination among selected genotypes. In this study we surveyed differentiation pools northern US latitudes (USDA Hardiness Zone seven less) originating from Eurasian...
Goat marketing study was conducted in eleven districts with the objectives of exploration existing goat system western hills Nepal. The methodology households survey, Rapid Marketing Appraisal and use secondary data. Some centers are at village level, catchments, terminal level markets district headquarters. There some agents dealing from to municipalities. mainly found farmers middlemen catchments markets. In wholesalers were involved where as headquarters municipalities middlemen, butchers...
Kentucky has varied landscapes favorable for different land use cover and agroecosystem management. The changes in concerning a change landownership structure can potentially alter landscape diversity ecological productivity. This research examined the relationship among cover, ownership (small, medium, large parcel), productivity Scott, Morgan, Graves counties of Kentucky. Landsat 4–5 TM 8 OLI (30-meter) imagery were used supervised classification, accuracy assessment, detection at pixel...
In the North-Central United States, lowland ecotype switchgrass can increase yield by up to 50% compared with locally adapted but early flowering cultivars. However, ecotypes are not winter tolerant. The mechanism for damage is unknown previously has been associated late time. This study investigated heading date (measured two years) and survivorship three in a multi-generation population generated from winter-hardy individuals diverse southern populations. Sequencing data (311,776 markers)...
This study investigates the potential of Unmanned Aerial Vehicle (UAV) based multispectral imageries (MSI) at very high spatial resolution (1.67 cm/pixel) to monitor Alfalfa (Medicago sativa L.) canopy height and digital biomass. We used difference between Digital Surface Model (DSM) Terrain (DTM) maps calculate Canopy Height (CHM), which was then compared ground measurements. Although underestimation observed, we found a satisfactory relationship retrieved measured height. Furthermore,...
Abstract Sod‐seeding of depleted pastures with non‐bloating legumes can be a low‐cost pasture rejuvenation strategy for ranchers in the North American prairies. A study was conducted to determine if sainfoin ( Onobrychis vicifolia subsp. ) or cicer milkvetch (CMV) Astragalus L.) populations cultivars (hereinafter populations) used rejuvenate alfalfa Medicago sativa grass pastures. The included increased fitness grow and CMV that were selected early emergence rapid seedling growth. These...
Abstract High winter mortality limits biomass yield of lowland switchgrass ( Panicum virgatum L.) planted in the northern latitudes North America. Breeding cold tolerant cultivars requires many years due to its perennial growth habit and unpredictable selection pressure that is required identify winter‐hardy individuals. Identification causal genetic variants for survivorship would accelerate improvement production. The objective this study was allelic variation associated with populations...
Abstract Alfalfa ( Medicago sativa L.) ‐ grass or alfalfa sainfoin Onobrychis viciifolia Scop.) mixtures are commonly used for pastures in western Canada because of their high forage quality and low risk causing frothy bloat grazing animals. However, the proportion these two legumes declines mixed stands over time. The objective this study was to evaluate effectiveness selecting superior genotypes from clonally propagated under plant competition different growth environments. For study,...
Abstract Switchgrass ( Panicum virgatum L.) is one of several grass species being bred for use as a biomass crop to support the biofuel industry. Increases in yield are imperative ensure that crops such switchgrass can sustainably meet needs this Genomic selection strategy accelerate breeding gains complex traits yield. The goal study was conduct three cycles genomic previously trained Liberty population and compare cycle phenotypic selection, both which required 3 years complete. advanced...
Crop height and biomass are the two important phenotyping traits to screen forage population types at local regional scales. This study aims compare performances of multispectral RGB sensors onboard drones for quantitative retrievals crop very high resolution. We acquired unmanned aerial vehicle (UAV) images (MSIs) 1.67 cm spatial resolution visible data (RGB) 0.31 measured above-ground over alfalfa (Medicago sativa L.) breeding trials in Canadian Prairies. (1) For estimation, digital...
Sainfoin is a highly nutritious non-bloating leguminous forage crop of temperate regions. Despite properties, its use in pastures was limited due to low dry matter yield (DMY), lack persistence the mixed pasture, and slow regrowth. The paradigm then shifted when new sainfoin cultivars planted mixtures with alfalfa reduced 98% bloat incidence ruminants. Two experiments were conducted determine compatibility grass alfalfa. Experiment (Exp.) I established by drilling cv. Longview orchardgrass...
