C21-926 Camelina, developed at the Saskatoon Research and Development Centre, Saskatoon, Saskatchewan

Elite spring camelina breeding line C21-926 is derived from a cross between large-seeded line 09CS0041 and high oil line 07CS0003-86; both lines are derived from PGRC germplasm. Reciprocal crosses were followed by F1 and F2 seed production in the greenhouse. After three generations of pedigree selection for vigor (speed of plant development early in the season), superior agronomics, such as high number of branches, thick pod canopy, long racemes, and moderate plant height, as well as seed oil content and 1000-seed weight, a number of progeny lines were selected. F6 seed, hand harvested from the centre of the nursery plot, was sown in replicated yield trials in 2022 and 2023. Yield trial results indicated the line C21-926 to be agronomically similar to AAC 10CS0048, with similarly high seed yield (1869 vs. 1763 kg/ha) and seed oil content (42.9 vs. 42.5%), similar seed size (1.3 vs. 1.2 g/1000-seed) and a similar n-3/n-6 fatty acid ratio of the seed oil (both 1.5). C21-926 and AAC 10CS0048 on average matured at the same time (79 days after seeding). C21-926 has improved downy mildew resistance compared to AAC 10CS0048 (1 vs. 2.75 on a 1-5 scale). C21-926 is adapted to all soil zones of the Canadian Prairies.

DT2046 Canada Western Amber Durum Wheat, developed at the Swift Current Research and Development Centre, Swift Current, Saskatchewan

There is growing concern regarding durum wheat's need for improved straw strength to withstand the unpredictable weather conditions, as well as enhanced grain yield in the brown/dark brown soil zones, the primary durum production area. DT2046 exhibits very good straw strength with a short plant height. It has demonstrated superior yield performance in the brown/dark soil zone, coupled with high grain protein concentration and a comparable level of resistance to Fusarium-damaged kernels (a grading factor of FHB determining the quality of the grain) to the FHB intermediate rating cultivar. DT2046 was selected from the cross A1150-AKP04C/AAC Donlow. In three years of registration testing, DT2046 yielded 5.3% more than the mean of the checks. Averaged over 23 station years in the major durum growing region, DT2046 yielded 1.8% more than AAC Weyburn (the highest-yielding check), 2.0% more than AAC Schrader, 5.1% more than Brigade and 9.0% more than CDC Precision. Grain protein concentration of DT2046 was 0.4 unit higher than AAC Weyburn. Time to maturity of DT2046 was within the range of the checks and similar to CDC Precision. Test weight and kernel size of DT2046 were within the range of the checks. Plant height of DT2046 was significantly shorter than Brigade and AAC Schrader, similar to CDC Precision and AAC Weyburn. Lodging resistance of DT2046 was significantly better than AC Navigator, AAC Weyburn, AAC Schrader and numerically lower than CDC Precision and Brigade. DT2046 expressed resistance to leaf rust, stem rust, stripe rust and common bunt while expressing resistance to moderate susceptible to loose smut. DT2046 expressed a comparable level of resistance to Fusarium-damaged kernels as the durum cultivar AAC Schrader. DT2046 had low grain cadmium concentration and good milling performance, and its quality profile met the requirements of the CWAD class with the similar wheat protein concentrations as AAC Schrader on average.

LRC16-4656 Alfalfa, developed at the Lethbridge Research and Development Centre, Lethbridge, Alberta

LRC16-4656 alfalfa (Medicago sativa L.) is a synthetic population developed from selected survivor plants after a long-term grazing experiment in Lethbridge, AB. This population originated from a 1 acre block of AC Blue J that was subjected to continuous grazing from 2009 to 2016. Over this period, the stand thinned by at least 75%, and only the most resilient plants survived. These surviving plants, which demonstrated tolerance to repeated grazing and trampling, were allowed to open pollinate, leading to the accumulation of beneficial alleles associated with high yield and grazing tolerance. Yield trials were conducted in Creston, BC, Lethbridge, AB, and on acidic soils at Chain Lakes, AB. Across 15 site-year evaluations, LRC16-4656 outyielded the check cultivar Beaver by at least 15% in dry matter yield (DMY). Additionally, a six-year evaluation in Creston, BC, demonstrated that the DMY of LRC16-4656 remained stable over the years, whereas Beaver experienced a decline after the third production year. This indicates the superior persistence of LRC16-4656 under long-term production conditions.
