AAC Spitfire Durum Wheat

AAC Spitfire durum wheat (Triticum turgidum L. subsp. durum (Desf.) Husn.) is adapted to the durum production area of the Canadian prairies. Averaged over four years, AAC Spitfire yielded significantly more grain than Strongfield, AC Avonlea, and AC Navigator, but the protein concentration was significantly lower than AC Avonlea and Strongfield. AAC Spitfire had significantly shorter and stronger straw than Strongfield. AAC Spitfire is eligible for grades of Canada Western Amber Durum, and it has low grain cadmium concentration and higher yellow pigment concentration than the check cultivars.The accepted manuscript in pdf format is listed with the files at the bottom of this page.

Effects of media supplements on doubled haploid production in durum wheat

The efficiency of maize pollen induced doubled haploid (DH) production in durum wheat is low mainly because of poor germination of haploid embryos on culture media. The objective of this research was to investigate the effect of culture media supplements on DH production in durum wheat. Haploid durum embryos generated by the wheat x maize method from the cultivar Transcend and F1 plants of a cross were cultured on a basic medium supplemented with 1 mgL-1 3,6-dichloro-o-anisic acid (dicamba), 1 mgL-1 2,4-dichlorophenoxyacetic acid (2,4-D), 100 mgL-1 silver nitrate (AgNO3), 1 mgL-1 6-benzylaminopurine (BAP), 1 mgL-1 indole acetic acid (IAA), 1 mgL-1 naphthalene acetic acid (NAA), or 10 mgL-1 ascorbic acid. The proportion of haploid plantlets per embryo increased significantly by 33% with the AgNO3 supplemented medium over the basic medium, while the increase in proportion of doubled plants per embryo of 20% was not significant. The proportion of haploid plantlets was improved with BAP in the embryos of the F1 plants, but the proportion of haploid plantlets and DHs per embryo produced with ascorbic acid, and IAA were not different from the basic medium. Dicamba and NAA produced results less favorable than the control, and no germination occurred with 2,4-D. The advantage of AgNO3 was attributed to a reduction in microbial contamination of embryos.The accepted manuscript in pdf format is listed with the files at the bottom of this page.

AAC NRG097 Canada Western Special Purpose Spring Wheat

AAC NRG097, a hard red spring wheat (Triticum aestivum L.), was developed at the Swift Current Research and Development Centre (SCRDC), Agriculture and Agri-Food Canada (AAFC), Swift Current, SK. AAC NRG097 has grain yield and time to maturity within the range of the checks, a semidwarf stature, and heavier seed mass than the checks. It expressed resistance to prevalent races of both leaf rust and common bunt, while expressing an intermediate level of resistance to fusarium head blight. It received registration No. 7567 from the Variety Registration Office, Plant Production Division, Canadian Food Inspection Agency (CFIA) on 24 July, 2014. AAC NRG097 was granted Plant Breedersâ Rights certificate No. 5089 by the Plant Breedersâ Rights office, CFIA on 7 Aug. 2015. It is eligible for grades of Canada Western Special Purpose.The accepted manuscript in pdf format is listed with the files at the bottom of this page.

AAC Cabri Durum Wheat

AAC Cabri durum wheat (Triticum turgidum L. subsp. durum (Desf.) Husn.) is adapted to the durum production area of the Canadian prairies. AAC Cabri has a solid stem that provides protection against the wheat stem sawfly (Cephus cinctus Norton). Averaged over four years, AAC Cabri yielded significantly more grain than Strongfield, AC Avonlea, and AC Navigator, but the protein concentration was significantly lower than the high protein concentration cultivars AC Avonlea and Strongfield.

Agronomic Advancement in Tillage, Crop Rotation, Soil Health, and Genetic Gain in Durum Wheat Cultivation: A 17-Year Canadian Story

The global demands for various grains, including durum wheat (Triticum turgidum L. subsp. durum (Desf.) Husn.), are expected to increase substantially in the coming years, due to the ever-growing human population’s needs for food, feed, and fuel. Thus, providing consistent or increased durum grain to the world market is one of the priorities for policy-makers, researchers, and farmers. What are the major achievements in agronomic advancement for durum wheat cultivation in recent decades? How might the current cropping systems be improved to increase crop yield and quality and improve resource use efficiencies while minimizing input costs and decreasing negative impact on the environment? Canada is one of the major durum wheat producers in the world, as Canada contributes about 50% to global trade of durum grain. Canada’s research achievements in durum wheat might serve as a guide for advancing the cultivation of the crop in other regions/countries on the planet. This review summarizes the major Canadian research findings in the aspects of durum wheat agronomics during the period 2001 to 2017 years. It highlights the main advancements in seeding and tillage, crop rotation and diversification, and use of pulse-induced microbiomes to improve soil health and feedback mechanisms. The genetic gain and breeding for resistance against abiotic and biotic stresses are discussed. Finally, we identified the main constraints and suggested some near-term research priorities. The research findings highlighted in this review will be of use for other areas on the planet to increase durum wheat productivity, improve soil fertility and health, and enhance long-term sustainability
