Optimizing soil and fertilizer nitrogen use by intensively managed soft red winter wheat
… of Virginia during the 1981-82 through 1985-86 winter wheat growing seasons. The treatments in all experiments consisted of varying amounts of N fertilizer rates applied at Zadoks' growth stages 25 (GS 25) and 30 (GS 30). The research was divided into three studies. The first study was conducted …

Dry matter estimation and potassium fertilization of intensively managed soft red winter wheat
Dry matter production must be predicted to utilize nitrogen recommendation models for winter wheat at growth stage 30. Four methods of dry matter estimation were evaluated for their ability to predict dry matter production. The pasture probe, height, and rising plate methods did not have adequate …

Genomic Prediction and Genetic Dissection of Yield-Related Traits in Soft Red Winter Wheat
… carried out on highly quantitative traits in wheat. We utilized single-nucleotide polymorphism (SNP) data generated via a genotyping-by-sequencing (GBS) protocol to perform GWA on multiple yield-related traits using a panel of 329 soft red winter wheat genotypes grown in four environments. In …

Quantitative Trait Loci Associated with Waterlogging Tolerance in a Soft Red Winter Wheat Mapping Population
… maturity. Despite the impact of waterlogging on wheat production both globally and in the southeastern U.S., very little is known about the genetic control of waterlogging tolerance in wheat. The objective of this study was to determine the amount of genetic variation for vegetative stage …

Effect of 1B/1R Chromosomal Translocation on Dough Rheology of Soft Red Winter Wheat Flour
Nine 1B/1R translocated soft red winter wheat (SRWW) varieties and six non-1B/1R varieties from two crop years (1995-1996 and 1996-1997), grown in two Virginia locations (Warsaw and Blacksburg), were studied to evaluate the effects of the 1R rye chromosome on soft wheat flour quality and baking …

A Genome Wide Association Study for Fusarium Head Blight Resistance in Southern Soft Red Winter Wheat
… The objectives of this study are: 1) evaluate soft red winter wheat (SRWW) lines for resistance to FHB in terms of resistance to initial inoculum (incidence); resistance to spread within the head (severity); resistance to DON accumulation; and resistance to Fusarium damaged kernels (FDK), 2) …

Physiological Traits and Quantitative Trait Loci Associated with Nitrogen Use Efficiency in Soft Red Winter Wheat
Development of winter wheat (Triticum aestivum L.) cultivars capable of more efficient uptake and utilization of applied nitrogen (N) has the potential to increase grower profitability and reduce negative environmental consequences associated with N lost from the plant-soil system. The first study …

Identification and Mapping of Resistance to Puccinia striiformis and Puccinia triticina in Soft Red Winter Wheat
Disease resistance is critical in soft red winter wheat (Triticum aestivum L.) cultivars. Leaf rust caused by Puccinia triticina Eriks and stripe rust caused by Puccinia striiformis Westend. f.sp. tritici Eriks. are destructive pathogens of wheat. From 2014 to 2015 phenotypic data was collected at …

Genomic selection for glume blotch resistance and milling and baking quality traits in soft red winter wheat
Wheat (Triticum aestivum L.) is a major cereal crop with global importance, responsible for providing 20% of human calorie intake, commonly in the form of flour. Maintaining superior milling and baking quality while improving disease resistance are key objectives in a breeding program. Selection …

Effect of nitrogen, sulfur, and potassium chloride fertilization on the baking quality of soft red winter wheat
Soft red winter wheat (Saluda c.v.) was fertilized using three treatments; urea, urea + KCl, and urea + sulfur. The wheat was harvested and milled and the flour produced was used to evaluate the baking quality of the wheat. Objective tests were performed on the flour samples. Significant …

Flour quality and dough stickiness of soft red winter wheat lines with and without 1B/1R translocations
Wheat (Triticum aestivum L.) is one of the major cereals of the world. Farmers must produce wheat with good yield and quality to meet the high demands for wheat flour. To reduce disease and increase wheat yield, cultivars have been developed by replacing the short arm of chromosome 1B of wheat with …

Effect of Allelic Variation in Rht Loci on Plant Height and Grain Yield of Soft Red Winter Wheat (Triticum aestivum L.)
<p>Plant height in wheat (Triticum aestivum L.) is controlled in large part by two major Rht genes, Rht-B1 and Rht-D1, which pleiotropically impact lodging and grain yield. Prior to the Green Revolution, wheat varieties contained only ‘wild-type’ Rht alleles (Rht-B1a and Rht-D1a) and were tall and …

Evaluating Methods of Screening for Pre-Harvest Sprouting in Soft Red Winter Wheat and the Effect of Delayed Harvest on Flour Properties
… (PHS) and weathering throughout the mid-Atlantic soft red winter wheat (SRWW) (Triticum aestivum L.) growing region. Sprouting and weathering caused decreased flour quality due to lowered dough viscosity and decreased ability to withstand mixing and processing for baked goods. Due to its decreased …

Determination of Optimum Fall and Spring Nitrogen Fertilizer Rate for Maximizing Grain Yield of Soft Red Winter Wheat Sown at Variable Planting Dates
<p>An optimum planting date is important for winter wheat nitrogen (N) management as it dramatically changes the growing environment including temperature and moisture, ultimately affecting fertilizer efficiency and grain yield (GY). In Arkansas, high precipitation in the fall often forces farmers …
