“…FHB susceptible hard red spring wheat cultivars with FHB scores ranging from 5 to 9, Linkert 27 , MN00269, MN10281-1-98, MN11492-6, Ulen 28 , Wheaton 29 , and FHB moderately resistant (MR) cultivars with FHB scores ranging from 2 to 4, (Bolles 30 , Glenn 31 , Lang-MN 32 , MN08172-3-10, MN11394-6, RB07 33 , Rollag 34 , Sabin 35 , Shelly 36 ) (Table 1 ), were grown in controlled environment growth chambers according to the methods outlined in Hay, et al 10 . The relative FHB resistance of wheat cultivars is based on evaluations in 6 or more inoculated, misted field environments for FHB traits: incidence, severity, Visual Scabby Kernels, and DON contamination.…”

The nutritional integrity of wheat is jeopardized by rapidly rising atmospheric carbon dioxide (CO2) and the associated emergence and enhanced virulence of plant pathogens. To evaluate how disease resistance traits may impact wheat climate resilience, 15 wheat cultivars with varying levels of resistance to Fusarium Head Blight (FHB) were grown at ambient and elevated CO2. Although all wheat cultivars had increased yield when grown at elevated CO2, the nutritional contents of FHB moderately resistant (MR) cultivars were impacted more than susceptible cultivars. At elevated CO2, the MR cultivars had more significant differences in plant growth, grain protein, starch, fructan, and macro and micro-nutrient content compared with susceptible wheat. Furthermore, changes in protein, starch, phosphorus, and magnesium content were correlated with the cultivar FHB resistance rating, with more FHB resistant cultivars having greater changes in nutrient content. This is the first report of a correlation between the degree of plant pathogen resistance and grain nutritional content loss in response to elevated CO2. Our results demonstrate the importance of identifying wheat cultivars that can maintain nutritional integrity and FHB resistance in future atmospheric CO2 conditions.

“…Unfortunately, the irrigation system in the Crookston 2018 nursery failed, resulting in biased data, thus, the data from this location was omitted and only the data from St. Paul was used for further analysis in 2018. In all FHB nurseries five checks (Alsen (MR, [30], MN00269 (S), Roblin (S), Rollag (MR, [31]), and Wheaton (S, [32])) were planted for every one hundred plots. Procedures for misting, inoculation and data collection for the FHB traits disease index (DIS), visually scabby kernels (VSK) and micro-test weight (MicroTwt) were as described by Fuentes-Granados et al [33].…”

Optimizing Training Population Size and Content to Improve Prediction Accuracy of FHB-Related Traits in Wheat

Genomic selection combines phenotypic and molecular marker data from a training population to predict the genotypic values of untested lines. It can improve breeding efficiency as large pools of untested lines can be evaluated for selection. Training population (TP) composition is one of the most important factors affecting the accuracy of genomic prediction. The University of Minnesota wheat breeding program implements genomic selection at the F5 stage for Fusarium head blight (FHB) resistance. This study used field data for FHB resistance in wheat (Triticum aestivum L.) to investigate the use of small-size TPs designed with and without stratified sampling for three FHB traits in three different F5 populations (TP17, TP18, and TP19). We also compared the accuracies of these two TP design methods with the accuracy obtained from a large size TP. Lastly, we evaluated the impact on trait predictions when the parents of F5 lines were included in the TP. We found that the small size TP selected randomly, without stratification, had the lowest predictive ability across the three F5 populations and across the three traits. This trend was statistically significant (p = 0.05) for all three traits in TP17 and two traits in TP18. Designing a small-size TP by stratified sampling led to a higher accuracy than a large-size TP in most traits across TP18 and TP19; this is because stratified sampling allowed the selection of a small set of closely related lines. We also observed that the addition of parental lines to the TP and evaluating the TP in two replications led to an increase in predictive abilities in most cases.

“…MN‐Washburn has good lodging resistance with a score of 0.54 on a 0–9 scale (0 = no lodging and 9 = lodged) across 41 locations where differential lodging occurred from 2014 to 2018 (Table 1). This level of lodging resistance is not significantly different than the strongest cultivars tested, including ‘Linkert’ (Anderson et al., 2018b) (0.16), ‘WB‐Mayville’ (PI 661061) (0.43), and ‘Rollag’ (Anderson et al., 2015) (0.77). According to DNA marker analyses (Ellis et al.…”

MN-Washburn' (Reg. no. CV-1184, PI 694049) hard red spring wheat (Triticum aestivum L.) was released by the University of Minnesota Agricultural Experiment Station in 2019 because of its high grain yield, good lodging resistance, and end-use quality characteristics. MN-Washburn also had good disease resistance, including resistance to Barley yellow dwarf virus (BYDV) and field resistance to the Ug99 race group of stem rust. The BYDV resistance of MN-Washburn results from the introgression of a chromosome 7D translocation containing Thinopyrum intermedium resistance gene bdv2 from the introgression line TC14. MN-Washburn is a mid-late maturity cultivar with below-average plant height due to the semi-dwarfing genes Rht-B1 and Rht24. MN-Washburn has good resistance to prevalent races of pathogens causing leaf rust, stripe rust, and stem rust and is well-adapted to the north central United States.
