Climate changes leading to higher summer temperatures can adversely affect cool season crops like spring barley. In the Upper Midwest region of the United States, one option for escaping this stress factor is to plant winter or facultative type cultivars in the autumn and then harvest in early summer before the onset of high-temperature stress. However, the major challenge in breeding such cultivars is incorporating sufficient winter hardiness to survive the extremely low temperatures that commonly occur in this production region. To broaden the genetic base for winter hardiness in the University of Minnesota breeding program, 2,214 accessions from the …

Quantitative Trait Loci Mapping For Vigour And Survival Traits Of Barley Seedlings After Germinating Under Salinity Stress, Edward Mwando, Tefera Angessa, Yong Han, Gaofeng Zhou, Chengdao Li

Grain and Other Field Crops Research Articles

Seed germination and seedling establishment are the most critical stages in the barley (Hordeum vulgare ssp. vulgare L.) life cycle that contribute substantially to grain yield. These two phases are exposed to several forms of environmental stresses such as salinity due to high level of salt accumulation in the soil rhizosphere where seed germination takes place and seedlings emerge from. Previously, we have reported genotypic variability and independent QTLs associated with salinity tolerance at seedling and germination stages. However, genotypic studies on revival of a seedling germinating under salinity stress are yet to close the lack of information between germination …

High Plains Wheat Mosaic Virus: An Enigmatic Disease Of Wheat And Corn Causing The High Plains Disease, Satyanarayana Tatineni, Gary Hein

Department of Entomology: Faculty Publications

Brief history: In 1993, severe mosaic and necrosis symptoms were observed on corn (maize) and wheat from several Great Plains states of the USA. Based on the geographical location of infections, the disease was named High Plains disease and the causal agent was tentatively named High Plains virus. Subsequently, researchers renamed this virus as maize red stripe virus and wheat mosaic virus to represent the host and symptom phenotype of the virus. After sequencing the genome of the pathogen, the causal agent of High Plains disease was officially named as High Plains wheat mosaic virus. Hence, High Plains virus, …

Perspectives On Low Temperature Tolerance And Vernalization Sensitivity In Barley: Prospects For Facultative Growth Habit, Maria Munoz-Amatriain, Javier Hernandez, Dustin Herb, P Stephen Baenziger, Anne Marie Bochard, Flavio Capettini, Ana Casas, Alfonso Cuesta-Marcos, Claus Einfeldt, Scott Fisk, Amelie Genty, Laura Helgerson, Markus Herz, Gongshe Hu, Ernesto Igartua, Ildiko Karsai, Toshiki Nakamura, Kazuhiro Sato, Kevin Smith, Eric Stockinger, William Thomas, Patrick Hayes

Department of Agronomy and Horticulture: Faculty Publications

One option to achieving greater resiliency for barley production in the face of climate change is to explore the potential of winter and facultative growth habits: for both types, low temperature tolerance (LTT) and vernalization sensitivity are key traits. Sensitivity to short-day photoperiod is a desirable attribute for facultative types. In order to broaden our understanding of the genetics of these phenotypes, we mapped quantitative trait loci (QTLs) and identified candidate genes using a genome-wide association studies (GWAS) panel composed of 882 barley accessions that was genotyped with the Illumina 9K single-nucleotide polymorphism (SNP) chip. Fifteen loci including 5 known …

Short And Long Term Effects Of Lime And Gypsum Applications On Acid Soils In A Water-Limited Environment: 1. Grain Yield Response And Nutrient Concentration, Geoff Anderson, Shahab Pathan, James Easton, David Hall, Rajesh Sharma

Grain and Other Field Crops Research Articles

Surface (0–10 cm) and subsoil (soil layers below 10 cm) acidity and resulting aluminum (Al) toxicity reduce crop grain yields. In South Western Australia (SWA), these constraints affect 14.2 million hectares or 53% of the agricultural area. Both lime (L, CaCO3) and gypsum (G, CaSO4) application can decrease the toxic effect of Al, leading to an increase in crop grain yields. Within the region, it is unclear if G alone or the combined use of L and G has a role in alleviating soil acidity in SWA, due to low sulfate S (SO4–S) sorption properties of the soil. We present …

Yield And Yield Component Development In Dual-Purpose Barley, A. K. Singh, Pradeep Saxena

IGC Proceedings (1977-2023)

Barley (Hordeum vulgare L.) is a widely adapted small-grain annual cereal and is a key feed and fodder in India (Kharub et al., 2013). Barley can provide nutrition to the animals through its green fodder at vegetative stage and grains after harvest from the regenerated plants. The vegetative portion of the crop is valuable as a source of pasture, cut green forage, and straw. Their relative importance is determined at different ontogenetic stages of plant. An area of barley breeding receiving increasing attention is the development of dual-purpose (green forage and grain) varieties for plains as well as …

Fodder Yield And Quality Of Egyptian Clover (Trifolium Alexandrinum L.), Annual Ryegrass (Lolium Multiflorum Lam.), And Barley (Hordeum Vulgare L.) Monocultures As Affected By Organic And Mineral Fertilization, Heba Sabry Attia Salama

IGC Proceedings (1977-2023)

Egyptian clover (Trifolium alexandrinum L.) is the most important forage legume crop in Egypt. Despite the fact that its yield and protein content are high, it is characterized by low dry matter content especially in the 1st cut, in addition to its limited energy supply, attributed to the low carbohydrate content. Therefore, there is a pressing need to introduce some promising winter annual forage grasses, like barley (Hordeum vulgare L.) and ryegrass (Lolium multiflorum L.), and investigate their performance under the Egyptian agricultural conditions. This would enhance the Egyptian animal production systems by providing a high-quality feed …

Winter Crop Evaluation For Silage And Forage Quality In Korea, J. D. Kim, H. W. Lee, J. K. Lee, J. K. Kim, C. H. Kwon

IGC Proceedings (1977-2023)

Winter crops of rye, barley, oats and Italian ryegrass are used alone or combined as silage crops or green forage in autumn and spring in Korea. The production and utilization of winter crops have been increasing since 2000, because of high yield and double cropping potential in the rice field after harvesting rice. An advantage of these winter crops is that they are produced in the cool season. However, a main problem in making silage with these winter crops is that they are sometimes poor in quality for various reasons.

Therefore we conducted a survey of farms and forage selling …

Determination Of Optimum Harvest Date For Winter Malting Quality Barley In Northwest Arkansas, Paul Wolf

Crop, Soil and Environmental Sciences Undergraduate Honors Theses

Due to the strict quality requirements, only 10 percent of worldwide barley is used for malting, though malting quality barley comes with a price increase of up to 50 percent or higher. With the craft brewery industry growing in Northwest Arkansas there is a growing demand for locally sourced malt quality barley. However, data is lacking regarding production practices for barley in Arkansas. The optimum harvest date for malting quality barley is at physiological maturity. This is because many of the malting traits (such as germination energy) decline as harvest is delayed, which will make it difficult to meet the …

Salt Stress Induces Non-Cg Methylation In Coding Regions Of Barley Seedlings (Hordeum Vulgare), Moumouni Konate, Michael J. Wilkinson, Benjamin T. Mayne, Stephen M. Pederson, Eileen S. Scott, Bettina Berger, Carlos M. Rodriguez Lopez

Horticulture Faculty Publications

Salinity can negatively impact crop growth and yield. Changes in DNA methylation are known to occur when plants are challenged by stress and have been associated with the regulation of stress-response genes. However, the role of DNA-methylation in moderating gene expression in response to salt stress has been relatively poorly studied among crops such as barley. Here, we assessed the extent of salt-induced alterations of DNA methylation in barley and their putative role in perturbed gene expression. Using Next Generation Sequencing, we screened the leaf and root methylomes of five divergent barley varieties grown under control and three salt concentrations, …

Biosystems and Agricultural Engineering Faculty Publications

Grain and oilseed crops stored in bins undergo compaction due to overbearing pressure of the grain inside the structure. Thus, volume measurements of grain in bins need to be combined with the amount of packing (usually called pack factor) in addition to the initial density so that the mass in the structure can be calculated. Multiple pack factor prediction methods are in use in the grain industry, but they have only been validated in the literature and compared with field data for corn and hard red winter wheat. Predictions from WPACKING, the program in ASABE Standard EP413.2, and two standard …
