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

Forced Air

The soft spring wheat (Triticum aestivum L.) cultivars Dirkwin and Fielder, and the hard red spring wheat cultivar Neepawa were grown under irrigation for 2 yr. Plots were harvested at seven kernel moisture contents (KMC) in the 45–15% moisture range. Material was dried in the field (windrowed) or artificially dried in a forced-air oven at 50 °C after threshing. Yield, test weight, 100-kernel weight, grain N, falling number and commercial grade were determined. Yield and grain N content were not affected by cutting time or drying method. Test weight of artificially dried material increased as cutting was delayed until lower KMC values were reached. In the windrowed treatment, test weight of Neepawa changed very little with cutting time, while that of Dirkwin and Fielder increased to a maximum at 25% KMC. The 1000-kernel weights of the cultivars increased as KMC fell in one of the two years. Falling number was constant for all cutting times in the windrowed treatment, but increased linearly as KMC at harvest fell in the artifically dried treatment. Commercial grades in the windrowed material had reached maximum by 35% KMC in all three cultivars. In the artificially dried material, maximum grades were not obtained unless cutting was delayed until KMC values of 20% or less were reached. Material cut at higher KMC levels lost grade due to the presence of immature kernels and to low test weight.

Based on 34 replicated trials over 3 yr, Stettler, a doubled haploid hard red spring wheat (Triticum aestivum L.), expressed significantly higher grain yield than all checks except Superb. Wheat and flour protein concentration were significantly greater than all of the checks except Lillian. It matured significantly later than AC Barrie and Katepwa but earlier than Superb. Stettler was significantly shorter than all of the checks except Superb and was more resistant to lodging than Katepwa and Laura. Stettler had high grain volume weight and intermediate kernel weight relative to the checks, and meets the end-use quality specifications of the Canada Western Red Spring wheat market class. Stettler expressed resistance to prevalent races of stem rust, common bunt and loose smut, with moderate susceptibility to prevalent races of leaf rust and fusarium head blight.Key words: Triticum aestivum L., cultivar description, grain yield, protein, disease resistance, doubled haploid

Helios hard red spring wheat (Triticum aestivum L.) has expressed high grain yield and medium time to maturity. The straw length and strength, volume weight, and seed size were intermediate to the check cultivars. It expressed resistance to prevalent races of stem rust and loose smut, intermediate resistance to common bunt and Fusarium head blight, and moderate susceptibility to leaf rust and leaf spots. It expressed resistance to pre-harvest sprouting and high Hagberg falling number. The end-use suitability of Helios was similar to that of the controls and, therefore, it is eligible for all grades of the Canada Western Red Spring (CWRS) wheat class.

AAC Redstar is an early maturing, high yielding hard red spring wheat (Triticum aestivum L.) cultivar that is well adapted to the northern Canadian Prairies and eligible for grades of Canada Western Red Spring (CWRS) wheat. Over three years (2016-2018) of testing in the Parkland Wheat Cooperative registration trials, AAC Redstar was 11% higher yielding than AC Splendor, 6% higher than Parata, and 4% higher than Glenn and Carberry. AAC Redstar matured 3 days earlier than Glenn, 2 days earlier than Carberry and had similar maturity to Parata. AAC Redstar was shorter than all checks except Carberry and had better lodging resistance compared to all the check cultivars in the registration trial. The test weight and thousand kernel weight of AAC Redstar were similar to Carberry. The grain protein concentration of AAC Redstar was 0.2% lower than Carberry. AAC Redstar was rated moderately resistant to Fusarium head blight, leaf rust, stripe rust and common bunt. AAC Redstar had resistant reactions to loose smut, and stem rust. AAC Redstar was registered under the CWRS market class.

Abstract A monitoring program was conducted for trace elements in Western Canadian Hard Red Spring wheat (Triticum aestivum L.). Samples were selected from harvest survey samples submitted by producers from crop districts in Manitoba, Saskatchewan, and Alberta for 1996, 1997, and 1998 crops. The analytical quality control measures used in these surveys are described along with the results for Cd, Cu, Fe, Mn, Se, and Zn. Accuracy and precision for the analyses fell within the acceptable control limits. Year-to-year variations in grain chemistry were small for Cd, Mn, Se, and Zn, but Cu and Fe contents showed 12 and 9% decreases, respectively, over the 3 years. The overall variability for the plant-essential trace elements—Cu, Fe, Mn, and Zn—was low compared with that for Cd and Se. The spatial variation in crop chemistry across the Canadian Prairie wheat-producing region was greater than the year-to-year variations. Soil properties were major factors in controlling Cd and Se levels in grain.

Plot Design

Three cultivars of wheat (Triticum aestivum L. em Thell.), Glenlea, Pitic 62 and Neepawa, were grown in a seeding rate and row spacing experiment at two locations in 1972 and 1973. In a split-plot design, row spacings of 15, 23 and 30 cm were used as main plots, and subplot seeding rates of 33.6, 67.3 and 100.9 kg/ha were applied for each cultivar. Data were collected on yield, days to maturity, plant height, lodging, kernel weight and test weight. The few significant effects of row spacing indicated that narrow row spacings tend to increase yield and decrease days to maturity. Higher seeding rates per unit area generally resulted in higher yields for all cultivars and, to some extent, earlier maturity. Glenlea wheat seeded at 100.9 kg/ha gave the highest yield in all tests, and at this seeding rate took an average 125 days to reach maturity, compared to 120 days for Neepawa and 129 days for Pitic 62. Seeding rate had virtually no effect on height, kernel weight or test weight of any of the wheats.
