registration of the triticeae cap Spring Wheat nested association mapping population
Journal of Plant Registrations, 2019Co-Authors: Nk Blake, Michael O Pumphrey, Jl Jannick, Ea Akhunov, Karl D Glover, Shiaoman Chao, Katherine W Jordan, Jorge Dubcovsky, Harold E Bockelman, Le TalbertAbstract:Author(s): Blake, NK; Pumphrey, M; Glover, K; Chao, S; Jordan, K; Jannick, JL; Akhunov, EA; Dubcovsky, J; Bockelman, H; Talbert, LE | Abstract: © 2019 Crop Science Society of America. All rights reserved. The Triticeae-CAP Spring Wheat nested association mapping population (Reg. No. MP-10, NSL 527060 MAP) consisting of recombinant inbred line (RIL) populations derived from 32 Spring Wheat (Triticum aestivum L.) accessions each crossed to a common Spring Wheat parent, ‘Berkut’, has been released. The Spring Wheat accessions consisted of 29 landraces and three cultivars. Each population consists of approximately 75 lines for a total of 2325 RILs (Reg. Nos. GSTR No. 14701–GSTR 17133). The RILs have all been genotyped with the Illumina Wheat iSelect 90K single nucleotide polymorphism array using the Infinium assay method and through genotype-by-sequencing. This nested association mapping population provides a genotyped germplasm resource for the Wheat community. A potential strategy for use of the material is to screen the parents for a trait of interest, followed by analysis of RIL of populations that are likely to be segregating for a target trait or sequence.

influence of genotype environment and nitrogen management on Spring Wheat quality
Crop Science, 2004Co-Authors: E Souza, J M Martin, D K Habernicht, Mary J Guttieri, K Obrien, S P Lanning, R Mclean, G R Carlson, Le TalbertAbstract:Bread baking is the primary end-use criterion used to select hard Spring Wheat (Triticum aestivum L.) genotypes for the northwestern USA, yet the use of hard Wheats has expanded beyond traditional pan breads to include Asian noodles. We assessed the relative influence of genotype, N management, and location on quality characteristics of a set of Spring Wheat cultivars that provided a range in gluten strength and acceptability for bread and Asian noodle quality, and determined whether grain characteristics could predict bread and/or noodle market suitability. Seven Spring cultivars were grown at four locations across 3 yr with two levels of N fertilizer in irrigated and moisture-limited conditions. Bread quality, alkaline noodle color, and Chinese noodle color and texture were assessed on grain samples. Cultivar was the most important determinant of bread and noodle quality traits in both the irrigated and moisture-limited environments. Nitrogen level influenced only Chinese noodle color in irrigated environments, but impacted test weight, flour ash, loaf volume, and bake absorption in moisture-limited environments. Responses to N management and location were usually not cultivar specific, as interactions were not important relative to main effects of cultivar and location. Grain protein had more value than test weight or grain hardness in predicting bread and noodle quality, and was most useful in predicting loaf volume and Chinese noodle color characteristics. Cultivar selection is critical for achieving a desired end use, with location effects being of secondary importance. Nitrogen management for a particular end use will be difficult, with N level being much less important than cultivar selection and location. Grain protein may be the best predictor of the suitability of a particular cultivar produced in a specific year for alternative end-use possibilities, with high-protein grain most suitable for bread production and low-protein, high-quality grain more suitable for noodle production.

end use quality of hard red and hard white Spring Wheat contaminated with grain of contrasting classes
Cereal Chemistry, 2002Co-Authors: D K Habernicht, J M Martin, Le TalbertAbstract:ABSTRACT Short growing seasons and lack of water limit the number of crops that can be productively grown in the Northern Great Plains, but Wheat is uniquely adapted to the region. Growers interested in diversification of their operations are growing more than one class of Wheat to target different markets. This has led to the challenge of maintaining class purity, in that contamination with alternate classes results in lower prices to the farmer. The primary rationale is that mixtures may have poor end-use quality. In these experiments, we tested hard red Spring Wheat and hard white Spring Wheat contaminated with different levels of soft white Spring Wheat, durum Wheat, hull-less barley, and the hard Wheat of the alternate kernel color for milling and baking quality. Our results showed that contamination of hard red and hard white Spring Wheat with soft white Wheat and hull-less barley often influenced end-use quality in that flour yield was negatively affected at relatively low levels. Loaf volume was n...

genetic diversity in hard red Spring Wheat based on sequence tagged site pcr markers
Crop Science, 1994Co-Authors: H B Chen, J M Martin, Matt Lavin, Le TalbertAbstract:Genetic variation among Wheat (Triticum aestivum L.) parents is necessary to derive superior progeny from crossing and selection. However, crosses are often performed among elite lines with similar agronomic and end-use characteristics. Thus, the potential exists for an undesirable narrowing of the germplasm base for any particular class of Wheat. The relative genetic diversity within hard red Spring Wheat was determined in comparison to a sample of Wheat accessions representing an array of types and geographic origins. Three groups of accessions were assayed for the frequencies of DNA polymorphism using a total of 38 sequence-tagged-site primer sets with polymerase chain reaction. Group I contained 10 elite hard red Spring Wheat cultivars under production in Montana and North Dakota, Group II included 15 hard red Spring Wheat cultivars and lines from the North American Great Plains, and Group III contained 20 accessions representing a wide range of collection and morphological types [...]

characterization of leaf rust resistance in hard red Spring Wheat cultivars
Plant Disease, 2004Co-Authors: L M Oelke, J A KolmerAbstract:Oelke, L. M., and Kolmer, J. A. 2004. Characterization of leaf rust resistance in hard red Spring Wheat cultivars. Plant Dis. 88:1127-1133. Leaf rust, caused by Puccinia triticina Eriks., is the most common disease of Wheat (Triticum aestivum L.) in the United States and worldwide. The objective of this study was to characterize seedling and adult plant leaf rust resistance in hard red Spring Wheat cultivars grown in Minnesota, North Dakota, and South Dakota, and postulate the identity of the seedling leaf rust resistance genes in the cultivars. Twenty-six cultivars, near-isogenic lines of Thatcher Wheat that differ for single leaf rust resistance genes, and three Wheat cultivars with known leaf rust resistance genes, were tested with 11 different isolates of leaf rust collected from the United States and Canada. The leaf rust infection types produced on seedling plants of the cultivars in greenhouse tests were compared with the infection types produced by the same isolates on the Thatcher near-isogenic lines to postulate which seedling leaf rust resistance genes were present. Seedling leaf rust resistance genes Lr1, Lr2a, Lr10, Lr16, Lr21, and Lr24 were postulated to be present in Spring Wheat cultivars. Seedling genes Lr3, Lr14a, and Lr23 likely were present in some cultivars but could not be clearly identified in this study. Most of the cultivars had some level of adult plant leaf rust resistance, most likely due to Lr34. Cultivars that had seedling resistance genes Lr1, Lr2a, Lr10, or Lr16 had poor to intermediate levels of leaf rust resistance in field plots. Cultivars with combinations of seedling resistance genes Lr16 and Lr24 with additional adult plant resistance were highly resistant to leaf rust.
