“…No single QTL accounted for a large portion of the variation, which is supported by the later findings of Froese et al (2016). Froese et al ( 2016) used the 'Finch'/'Eltan' RIL mapping population (Balow et al, 2019) to examine genetic polymorphisms associated with Cephalosporium stripe resistance, and while they found numerous QTLs, no one QTL controlled for a major portion of the variation in resistance. Studies like these further suggest that mechanisms behind resistance and tolerance to this disease are complex and multiple genes are involved.…”

A mapping population (Reg. no. MP-15, NSL 540708 MAP) composed of a cross between the soft white common winter wheat (Triticum aestivum L. subsp. aestivum) 'Brundage' (PI 599193) and the soft white club winter wheat (T. aestivum L. subsp. compactum) 'Coda' (PI 594372) was developed to maximize diversity within the soft white market class. The population comprises 268 F 6:7 lines developed through single seed descent. The genetic linkage map consists of 2,144 DNA markers and is assigned to 32 linkage groups covering all chromosomes except 1D. This population was initially developed to determine additional markers linked to the Pch1 gene in wheat. It has further been used to identify quantitative trait loci (QTL) associated with resistance to other diseases such as Cephalosporium stripe (caused by Cephalosporium gramineum) and stripe rust (caused by Puccinia striiformis Westend. f. sp. tritici Erikss). The mapping population has also been used for identification of DNA markers associated with freezing tolerance, end-use quality, and the compactum locus.From the differences in traits between the parental lines, the Coda/Brundage population provides the opportunity for further inquiry into the genes behind the identified QTL. The parents have only been phenotypically screened for a limited number of traits, and further screening may identify more polymorphic traits which the population can be used to map. It can also serve as a validation population for marker-trait associations identified in other populations or other genetic studies such as recombination frequency.

Adoption of no-till systems in Eastern Washington has been slow due to the difficulty of managing wheat (Triticum aestivum L.) straw residue and the unknown decomposition potential of cultivars. We hypothesize that by analyzing wheat straw with near-infrared spectroscopy (NIRS), calibration models can be developed to accurately predict fiber and chemical constituents of wheat, determining straw decomposition potential. Straw from a panel of 480 soft winter wheat cultivars adapted to the Pacific Northwest are analyzed for neutral detergent fiber (NDF), acid detergent fiber (ADF), acid detergent lignin (ADL), cellulose, hemicellulose, carbon (C), and nitrogen (N). Using modified partial least squares regression and cross validation techniques, specific environment and broad-based NIRS models are calibrated and predictive ability is validated. R2cal values from broad models are better than the specific models, and are 0.85 (NDF), 0.86 (ADF), 0.65 (ADL), 0.88 (cellulose), 0.42 (hemicellulose), 0.67 (C), and 0.73 (N). The corresponding SEP values are 1.68% (NDF), 1.54% (ADF), 0.62% (ADL), 1.14% (cellulose), 1.11% (hemicellulose), 1.23% (C), and 0.06% (N). A Finch × Eltan breeding population is used to further validate models and prediction accuracies for variety selection within a breeding program scenario. The broad NIRS models prove useful for estimating high and low ranges of NDF, ADF, and cellulose in wheat cultivars which translate into characteristics of slow and fast decomposition potential.

Winter wheat (Triticum aestivum L.) undergoes a period of cold acclimation in order to survive the ensuing winter, which can bring freezing temperatures and snow mold infection. Tolerance of these stresses is conferred in part by accumulation of carbohydrates in the crown region. This study investigates the contributions of carbohydrate accumulation during a cold treatment among wheat lines that differ in their snow mold tolerance (SMT) or susceptibility (SMS) and freezing tolerance (FrT) or susceptibility (FrS). Two parent varieties and eight recombinant inbred lines (RILs) were analyzed. The selected RILs represent four combinations of tolerance: SMT/FrT, SMT/FrS, SMS/FrT, and SMS/FrS. It is hypothesized that carbohydrate accumulation and transcript expression will differ between sets of RILs. Liquid chromatography with a refractive index detector was used to quantify carbohydrate content at eight time points over the cold treatment period. Polysaccharide and sucrose content differed between SMT and SMS RILs at various time points, although there were no significant differences in glucose or fructose content. Glucose and fructose content differed between FrT and FrS RILs in this study, but no significant differences in polysaccharide or sucrose content. RNAseq was used to investigate differential transcript expression, followed by modular enrichment analysis, to reveal potential candidates for other mechanisms of tolerance, which included expected pathways such as oxidative stress, chitinase activity, and unexpected transcriptional pathways. These differences in carbohydrate accumulation and differential transcript expression begin to give insight into the differences of wheat lines when exposed to cold temperatures.
