Fusarium Head Blight in Hard Red Spring Wheat: Cultivar Responses to Natural Epidemics

AbstractWheat (Triticum aestivum L.) breeding involves improvement of a wide range of traits. However, selection for these traits is only acceptable if the end use quality of the wheat is not compromised. In hard red spring wheat, the predominant end use of flour is bread. In this study, milling and baking quality characteristics were compared in the hard red spring wheat ‘Apogee’ and a near-isogenic line of Apogee (‘A30’) that contains a spontaneous segmental deletion of the long arm of chromosome arm 3DL that is associated with enhanced resistance to Fusarium head blight caused by the fungal pathogen Fusarium graminearum (Schwabe). Apogee and A30 were grown together in replicated greenhouse experiments, and the resultant grain was used to compare a diverse spectrum of grain characteristics and milling and baking properties of the grain in the two wheat genotypes. The major difference detected was a significant increase in protein content in A30, which had nearly 21% more flour protein than Apogee. This difference did not affect any of the flour properties or baking characteristics evaluated, suggesting that the increased protein concentrations in A30 are not associated with the principal seed storage properties associated with baking quality. These results indicate that despite the size of the deletion in A30, no key genes associated with end use quality are located on that chromosome segment. The deletion may therefore find use in efforts to enhance Fusarium head blight in hard red spring wheat.

Superb is a hard red spring wheat (Triticum aestivum L.) adapted to the wheat-growing regions of the Canadian prairies, and meets the end-use quality specifications of the Canada Western Hard Red Spring wheat class. Superb was evaluated in the Central Bread Wheat Cooperative Registration Test in 1997, 1998 and 1999. Superb yielded significantly more than the cultivars Neepawa, Roblin, AC Majestic, and 5500HR and slightly more than McKenzie. Superb was resistant to leaf and stem rust. Its disease reaction was “intermediate” to loose smut and common root rot, and moderately resistant to common bunt. Leaf spot reaction of Superb was similar to the checks and its reaction to Fusarium head blight was intermediate.

The Individual

Fusarium head blight (FHB), caused by Fusarium graminearum, is one of the most damaging diseases that affect wheat in Canada. The disease is best managed by integrating host resistance and fungicides, mainly demethylation inhibitors. Research has shown that the effect of fungicides may be dependent on the level of resistance of the cultivar. However, whether the performance of genotypes carrying specific Sumai 3-derived major FHB quantitative trait loci is dependent on fungicide application has not been explored. In our study, the performance of near-isogenic lines (NILs; <1.0% genome/alleles from the resistance donor), carrying Fhb1 and Fhb5 in a hard red spring wheat cultivar CDC Go background compared with a moderately susceptible (MS) genotype, was evaluated with and without one application of metconazole during full flowering. Field experiments were conducted at five site-years in Saskatchewan, Canada, between 2016 and 2017. In both the individual and combined analysis (all trials), we found that the effect of NILs and metconazole in suppressing FHB symptoms and deoxynivalenol (DON) accumulation in the grain was additive. FHB severity was generally low and fungicide efficacy levels, relative to the untreated control, were increased in the MS cultivar than in the NILs carrying Fhb1 and Fhb5, which were least affected by the disease. The results confirm the importance of integrating fungicides with cultivar resistance to reduce FHB and DON, regardless of the presence of those well-characterized resistant genes.

Drought stress is becoming more prevalent with global warming, and has been shown to have large effects on gluten proteins linked to wheat bread making quality. Likewise, low temperature stress can detrimentally affect proteins in wheat. This study was done to determine the differential abundance of high molecular weight (HMW) glutenin proteins in a drought and low temperature stressed high quality hard red spring wheat cultivar (PAN3478), against a control. The treatments were applied in the greenhouse at the soft dough stage. HMW glutenin proteins were extracted from the flour, and were separated by using two-dimensional gel electrophoresis. Protein spots that had p values lower than 0.05 and fold values equal to or greater than 1.2 were considered to be significantly differentially abundant. These proteins were further analyzed by using tandem mass spectrometry. There was a 1.3 to 1.8 fold change in 17 protein spots due to the cold treatment. The drought treatment caused a 1.3 to 3.8 fold change in 19 protein spots. These spots matched either HMW or low molecular weight (LMW) glutenin subunits. In the latter case, the C subunits of LMW glutenins were notably found to be up-regulated under both stress conditions. All the proteins that have been identified can directly influence dough characteristics. Data are available via ProteomeXchange with the identifier PXD017578.

AAC Proclaim is a soft red spring wheat cultivar eligible for the Canada Western General Purpose (CWGP) wheat class. Evaluated in 18 trials grown over 2 yr in the General Purpose Wheat Cooperative Registration trial, AAC Proclaim yielded significantly lower than the CWGP checks, AC Andrew and Pasteur, and was 1 and 5 d earlier maturing, respectively. AAC Proclaim was significantly taller than the checks, but had similar straw strength. Test weight was higher than the checks and kernel mass was similar to AC Andrew. Based on visual assessments and deoxynivalenol testing over 3 yr, AAC Proclaim was rated as resistant to Fusarium head blight. It also expressed resistance to the prevalent races of leaf rust and moderate resistance to the prevalent races of stem rust and loose smut. AAC Proclaim showed susceptibility to infection by stripe rust and common bunt.

Sumai 3

ND2710 is a hard red spring wheat line with a very high level of resistance to Fusarium head blight (FHB). It was selected from the progeny of a cross between ND2603 (an advanced breeding line derived from the Sumai 3/Wheaton cross) and Grandin (a spring wheat cultivar). The FHB resistance of ND2710 is presumably derived from Sumai 3 because the other parents (Grandin and Wheaton) are very susceptible to FHB. To identify and map the quantitative trait loci (QTL) for FHB resistance in ND2710, we developed a mapping population consisting of 233 recombinant inbred lines (RILs) from the cross between ND2710 and the spring wheat cultivar Bobwhite. These RILs along with their parents and checks were evaluated for reactions to FHB in three greenhouse experiments and one field experiment during 2013 to 2014. The population was also genotyped with the wheat 90K iSelect single-nucleotide polymorphism (SNP) assay, and a genetic linkage map was developed with 1,373 non-cosegregating SNP markers, which were distributed on all 21 wheat chromosomes spanning 914.98 centimorgans of genetic distance. Genetic analyses using both phenotypic and genotypic data identified one major QTL (Qfhb.ndwp-3B) on the short arm of chromosome 3B, and three minor QTL (Qfhb.ndwp-6B, Qfhb.ndwp-2A, and Qfhb.ndwp-6A) on 6B, 2A, and 6A, respectively. The major QTL on 3B was detected in all experiments and explained 5 to 20% of the phenotypic variation, while the three minor QTL on 6B, 2A, and 6A explained 5 to 12% phenotypic variation in at least two experiments, except for Qfhb.ndwp-2A, which was only detected in the field experiment. Qfhb.ndwp-3B and Qfhb.ndwp-6B were mapped to the genomic regions containing Fhb1 and Fhb2, respectively, confirming that they originated from Sumai 3. The additive effect of the major and minor QTL may contribute to the high level of FHB resistance in ND2710. The SNP markers closely linked to the FHB resistance QTL will be useful for marker-assisted selection of FHB resistance in wheat breeding programs.
