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.

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

AAC Castle, an awned hard red spring wheat (Triticum aestivum L.), cultivar, combines high grain yield and good agronomic characteristics with excellent resistance to leaf, stem, stripe rust, common bunt and loose smut. It also expressed tolerance to the orange wheat blossom midge. Based on 39 station years of data in the registration trials from 2014 to 2016, the grain yield of AAC Castle was about 17% higher than 5700PR but similar to the other checks. AAC Castle was significantly shorter than AAC Foray and CDC Terrain, but had similar lodging resistance and maturity. AAC Castle had higher test weight, protein concentration, falling number and flour yield than AAC Foray and CDC Terrain. AAC Castle is eligible for grade of the Canada Prairie Spring Red wheat market class.

Lovitt hard red spring wheat (Triticum aestivum L.) is adapted to the Canadian prairies. Lovitt is earlier maturing than AC Barrie with similar grain yield and smaller kernels. Lovitt has resistance to prevalent races of leaf and stem rust and loose smut. Lovitt has very good pre-harvest sprouting resistance similar to RL4137. Lovitt is eligible for grades of the Canada Western Red Spring wheat class. Key words: Triticum aestivum L., cultivar description, resistance to leaf and stem rust, dormancy

Hucl, P. and Ramachandran, A. 2015. Agronomic characteristics of hard red spring wheat (Triticum aestivum L.) near-isogenic lines differing at the Waxy (Wx) locus. Can. J. Plant Sci. 95: 201–204. Null mutations of the Waxy gene in all three genomes of hexaploid wheat (Triticum aestivum L.) produce a waxy starch phenotype. The agronomic performance of 32 waxy, partially waxy and wild-type near-isogenic spring wheat lines and four check cultivars was assessed at two locations over three cropping seasons. Differences in grain yield, kernel weight and test weight among allelic groups were generally small. The results of our study suggest that no significantly negative effects are likely to occur in the commercial cultivation of partially waxy wheat lines derived from a CWRS cultivar.

Air (pneumatic) seeding systems that have seed row opener options that spread seed rather than place it in distinct rows may allow producers to uniformly distribute plants and increase seeding rates to improve cereal crop yield. A study was conducted to determine if seed placement configuration influenced hard red spring wheat (Triticum aestivum L.) response to seeding rate. The study was carried out at Melfort, SK, from 1997 to 1999, using three seed configurations (23 cm and 30 cm distinct row with a hoe opener; and a 20 cm spread using a 28 cm sweep on 23 cm row spacing) and four seeding rates (67, 100, 134, and 167 kg ha–1). Grain yield increased 6% when seeding rate was increased from 100 (recommended rate) to 168 kg ha–1 in 1997. Improved grain yield with increased seeding rates was related to greater kernels head–1. In the 2 following years, yield decreased by 9% when seeding rate was increased from 100 to 168 kg ha–1. Yield reductions in these years were associated with high yield potential (high soil N availability) and lodging, that in turn resulted in decreased kernels head–1 and kernel weight with increased seeding rates. Grain yield did not differ between the sweep and distinct rows, regardless of the seeding rate. Furthermore, the similar yields among the three seed configurations occurred despite lodging being less with sweeps compared with 23 or 30 cm row spacing at the highest seeding rate in 1998. The increased distance between wheat plants with sweeps did not improve grain yields as a result of reduced inter-plant competition, regardless of seeding rate. This absence of grain yield differences between the sweep and distinct row placement illustrates the yield stability associated with Canadian hard red spring wheat cultivars through yield component compensation.

Infinity hard red spring wheat (Triticum aestivum L.) has exhibited adaptation to a wide range of growing season temperatures and moisture availability. Infinity averaged significantly more grain yield than most other presently registered cultivars, and its grain protein concentration was significantly higher than that of Superb in the Saskatchewan Advisory Council trials. It matured significantly earlier than Superb. The straw length and strength, and volume weight of Infinity was intermediate to the check cultivars. Its seed size was smaller than that of AC Barrie and Superb. Infinity expressed resistance to prevalent races of stem rust and loose smut, moderate resistance to leaf rust and common bunt, and susceptibility to fusarium head blight. Infinity is eligible for all grades of the Canada Western Red Spring (CWRS) wheat class.
