Western Siberia is one of the major spring wheat regions of Russia, cultivating over 7 Mha. The objective of the study was to evaluate the variation of macro- and microelements, and of trace metals in four distinct groups of genetic resources: primary synthetics from CIMMYT (37 entries), primary synthetics from Japan (8), US hard red spring wheat cultivars (14), and material from the Kazakhstan–Siberian Network on Spring Wheat Improvement (KASIB) (74). The experiment was conducted at Omsk State Agrarian University, using a random complete block design with four replicates in 2017 and 2018. Concentrations of 15 elements were included in the analysis: macroelements, Ca, K, Mg, P, and S; microelements, Fe, Cu, Mn, and Zn; toxic trace elements, Cd, Co, Ni; and trace elements, Mo, Rb, and Sr. Protein content was found to be positively correlated with the concentrations of 11 of the elements in one or both years. Multiple regression was used to adjust the concentration of each element, based on significant correlations with agronomic traits and macroelements. All 15 elements were evaluated for their suitability for genetic enhancement, considering phenotypic variation, their share of the genetic component in this variation, as well as the dependence of the element concentration on other traits. Three trace elements (Sr, Mo, and Co) were identified as traits that were relatively easy to enhance through breeding. These were followed by Ca, Cd, Rb, and K. The important biofortification elements Mn and Zn were among the traits that were difficult to enhance genetically. The CIMMYT and Japanese synthetics had significantly higher concentrations of K and Sr, compared to the local check. The Japanese synthetics also had the highest concentrations of Ca, S, Cd, and Mo. The US cultivars had concentrations of Ca as high as the Japanese synthetics, and the highest concentrations of Mg and Fe. KASIB’s germplasm had near-average values for most elements. Superior germplasm, with high macro- and microelement concentrations and low trace-element concentrations, was found in all groups of material included.

AbstractThe wheat midge, Sitodiplosis mosellana Géhin (Diptera: Cecidomyiidae), is a serious pest of spring wheat in North America. Currently, most commercial cultivars in the state of Montana, United States of America are susceptible. A study was conducted to assess the variability of adapted spring wheat cultivars to wheat midge infestations. A secondary objective was to determine the relationship between wheat midge infestation levels and spring wheat agronomic traits, including yield, test weight, grain protein, plant height, and heading date. This relationship was determined by evaluating 16 hard red spring wheat cultivars over a six-year period at the Northwestern Agricultural Research Center, near Kalispell, Montana. Levels of infestation had a negative impact on grain yield and test weight. Overall, the average infestation level was 40 larvae/spike with the lowest being observed with “Reeder” and the highest for “Thatcher”. Concurrently, “Reeder” had the highest yield, whereas “Thatcher” had the lowest yield and the highest grain protein, demonstrating that wheat midge infestations were positively associated with grain protein. Heading date had a positive association with midge density with higher infestations associated with later maturing cultivars. The economic injury level was estimated at 12 and 20 midge larvae/spike for a market price of USD $0.27 and USD $0.16/kg, respectively.

End Use

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.

KANE is a hard red spring wheat that meets the end-use quality and kernel visual distinguishability specifications of the Canada Western Red Spring market class. KANE was found to be adapted to the wheat-growing regions of Manitoba and eastern Saskatchewan from the data provided by the Central Bread Wheat Cooperative registration test in 2003–2005. In comparison with the check cultivars Katepwa, McKenzie, CDC Teal, AC Barrie, and Superb, the overall grain yield of KANE was similar to the high yield checks McKenzie and Superb. Compared with the highest yielding check McKenzie, KANE was 1.7 d later maturing, was 6 cm shorter, had stronger straw, and was significantly higher (1.1 kg hL-1) in test weight. KANE is resistant to the prevalent races of leaf rust and stem rust. Resistance to common bunt and loose smut was intermediate, being similar to CDC Teal and McKenzie, respectively. Resistance to fusarium head blight was similar to AC Barrie. KANE has good preharvest sprouting resistance with similar or lower sprouting scores compared to the best check in 4 out of 5 yr of testing. End-use quality tests showed that KANE had a 0.7% higher flour extraction rate than the best checks and was within the range of the checks for the other quality traits.

Hard Red Spring Wheat

Two hard red spring wheat (Triticum aestivum L.) cultivars, Neepawa and Columbus, were harvested at 5% kernel moisture content (KMC) intervals from 45% to 15% for three growing seasons. Two drying treatments, field drying in windrows and oven drying were evaluated. Yield, test weight, 1000-kernel weight, protein-N, falling number and commercial grade were determined. Protein-N and 1000-kernel weight were reduced when the crop was harvested above 40% and 35% KMC, respectively, but were not affected by drying method. Yield losses up to 12% were recorded with windrowing. Windrowing at 35% KMC or less in warm, dry conditions had little effect on test weight, falling numbers, and grade. Under wet conditions, windrowing above 20% KMC resulted in lower falling numbers and a loss of grade. Direct combining and artificial drying above 20% KMC lowered test weights, falling numbers and grade. The current recommendation of windrowing at 35% KMC is supported under good harvest conditions but either windrowing or straight combining at 20% KMC would be superior under damp harvest conditions.Key words: Triticum aestivum L., kernel moisture content, drying method, falling number, quality, grade
