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.

Spaner, D., Navabi, A., Strenzke, K., Iqbal, M. and Beres, B. 2015. Coleman hard red spring wheat. Can. J. Plant Sci. 95: 1037–1041. ‘Coleman’ hard red spring wheat is an awned, hollow-stemmed cultivar of high yield potential adapted to the wheat growing regions of western Canada. Averaged over 30 site-years, during 3 yr of testing in the Parkland Wheat Cooperative Registration Test (2010–2012), Coleman was higher yielding than Katepwa (8.5%) (P≤0.05), AC Splendor (5.8%) (P≤0.05), CDC Teal (2.1%) and CDC Osler (2%), exhibited maturity, height and lodging resistance similar to, or in the range of the checks, had higher test weights than the checks and showed good resistance to leaf, stem and stripe rust. Coleman exhibited Fusarium head blight resistance greater than and DON contamination levels lower than the check cultivars. Coleman exhibited susceptible reactions to common bunt and loose smut. End-use quality attributes of Coleman meet the specifications of the Canada Western Red Spring (CWRS) wheat market class.

Waskada is a hard red spring wheat that meets the end-use quality specifications of the Canada Western Red Spring wheat class. Waskada was found to be adapted to the wheat growing regions of the Canadian prairies based on data from the Central Bread Wheat Cooperative Registration Test in 2004, 2005 and 2006. In comparison with the check cultivars (Katepwa, McKenzie, CDC Teal, AC Barrie, and Superb), the grain yield of Waskada was similar to that of the best check in Manitoba and in Saskatchewan. Waskada matures 1 d later than AC Barrie and 1 d earlier than Superb. Waskada had similar height and lodging characteristics as Katepwa and McKenzie. The test weight of Waskada was 1.3 kg hL-1 higher than McKenzie, the best check. Waskada demonstrated moderate resistance to leaf rust but very good resistance to stem rust. Resistance to common bunt and loose smut was good, being similar to the more resistant checks Superb and Katepwa, respectively. Resistance to Fusarium head blight was better than the best check in four determinations made over the 3 yr of registration testing. Waskada appears to deter egg laying by the orange blossom wheat midge. Waskada has good preharvest sprouting resistance with similar or lower sprouting scores than the best check in 4 yr of testing, and it also maintained its falling numbers after natural or artificial weathering of spikes. End-use quality tests identified that Waskada had significantly higher amylograph viscosity than all checks except Superb. Waskada had a significantly lower loaf volume than CDC Teal and AC Barrie and was within the range of the checks for other quality traits.

J. Plant Sci. 94: 1297–1302. Peace is a hard red spring wheat (Triticum aestivum L.) adapted to the shorter-season wheat-growing regions of the Canadian prairies. Peace was evaluated in the Parkland Wheat Cooperative Test in 1999, 2000 and 2001. Peace exhibited grain yield similar to the check cultivars over 2 yr (1999–2000; Neepawa and Roblin) and over 3 yr (1999–2001; AC Barrie and AC Splendor) Peace matured a day earlier than AC Barrie but was 2 d later than AC Splendor over 3 yr of testing (1999–2001) and was a day later than Neepawa and Roblin over 2 yr of testing (1999–2000). Peace had test weight similar to the check cultivars. Peace was moderately resistant to leaf rust and loose smut and resistant to stem rust including the highly virulent Ug99 race of stem rust and common bunt. Peace was moderately susceptible to Fusarium head blight. Peace meets the end-use quality specifications of the Canada Western Red Spring wheat class.

Sumai 3

The effect of selection for two donor-QTL from Fusarium head blight (FHB) resistant spring wheat variety Sumai 3 on the reduction of deoxynivalenol (DON) content and FHB index was evaluated in field trials over two years (2008, 2009) following artificial inoculation with Fusarium culmorum. This study was conducted on populations of recombinant inbred lines derived from two crosses, Sumai 3/Swedget and Sumai 3/SG-S 191-01. DON content and FHB index were significantly reduced in both crosses in the genotype classes with two stacked donor QTL on chromosomes 3B and 5A in comparison to genotype classes with no donor QTL. In the cross Sumai 3/Swedget the selection for QTL alleles from 3B and 5A resulted in a 63.4% reduction in DON content, and a 51.8% reduction in the FHB index. Similarly, there was a 35.9% and 31.9% reduction, respectively, in the cross Sumai 3/SG-S 191-01. The single effect of the donor-QTL allele from 3B was significant only in the cross Sumai 3/Swedjet. The presence or absence of awns affected both DON content and FHB index in both populations, but was only significantly in the cross Sumai 3/SG-S 191-01. In this cross the effect of selection for fully awned genotypes was particularly evident on a reduction of both DON and FHB index in classes with neither donor QTL, or the 3B QTL. However, the data indicate that the “awnedness” effect on FHB resistance may be highly variable and is probably greater on reducing FHB symptoms than on DON content. The results confirmed that marker-based introgression of resistance QTLs on chromosomes 3B and 5A in traditional breeding materials can enrich populations for resistance types, but it was also shown that the effect of marker-based selection need not be large in all crosses and a similar effect can probably be reached by indirect selection for some FHB-related traits.

Thomas, J., Fox, S., McCallum, B., Fetch, T., Gilbert, J., Menzies, J., Wise, I., Smith, M., Gaudet, D., Niziol, D., Humphreys, G. and Brown, D. 2013. Vesper hard red spring wheat. Can. J. Plant Sci. 93: 315–321. Vesper is a high-yielding, hard red spring wheat that is adapted to the wheat-growing regions of Manitoba and Saskatchewan. In the Central Bread Wheat Cooperative Registration Trials of 2007, 2008 and 2009, Vesper out-yielded five check cultivars by an average of 12%, and Unity, which was the highest yielding check, by 4.6%. Lodging, height and maturity scores of Vesper were all intermediate (similar to the check mean). Pre-harvest sprouting resistance of Vesper was equivalent to the poorer checks (Katepwa and CDC Teal). Kernels of Vesper were heavier than all five checks and test weight was high (exceeded only by Unity). Vesper was resistant to leaf rust and was moderately resistant to stem rust and Fusarium head blight. Vesper was intermediately resistant to loose smut and was susceptible to common bunt. Spikes of Vesper showed two forms of resistance to wheat midge: antibiotic resistance (no larvae observed in the field) and antixenotic resistance (reduced egg numbers laid by caged ovipositing females). Over 3 yr of testing, end use quality of Vesper was rated as eligible for the Canada Western Red Spring (CWRS) market class of wheat. Kernels of Vesper were relatively hard with consequent high water absorption.

Based on 38 replicated trials over 3 yr, Alvena, hard red spring wheat (Triticum aestivum L.) expressed significantly higher mean grain yield than the checks. It was significantly earlier maturing than AC Barrie and significantly more resistant to lodging than Katepwa. Wheat protein concentration of Alvena was similar to the mean of the checks and flour protein concentration was significantly higher than the check mean. Amylograph viscosity was significantly lower than the mean of the checks. Alvena meets the end-use quality and Canadian Grain Commission’s kernel visual distinguishability specifications of the Canada Western Red Spring wheat market class. Alvena expressed moderate resistance to prevalent races of loose smut and stem rust, intermediate resistance to prevalent races of leaf rust and common bunt, and moderate susceptibility to fusarium head blight.
