Validation of several genes involved in stress related pathways regulated by waterlogging in contrasting barley genotypes
This project investigated the gene expression of several barley varieties when under waterlogging stress.
Optimum nitrogen fertilizer management strategies for modern corn hybrids in Manitoba
This project addressed all four “R’s” in the 4R Nutrient Stewardship framework for nitrogen fertilization of modern corn hybrids in Manitoba:applying the right rate, at the right source, in the right place, and at the right time.
Can-NAM: Capturing genetic variation for Canadian wheat improvement
The loss of genetic diversity of wheat has reduced the potential to improve yield and also leaves the crop vulnerable to disease and pest. Wild wheat relatives and exotic species are a valuable resource of new genes for cultivated wheat improvement. Nested Association Mapping (NAM) is an ideal genetic design population to identify robust genotype and phenotype associations. This project hopes to promote future phenotyping effeors within this valuable resource for both public and private breeding partners.
CTAG2 – Canadian triticum advancement through genomics
Wheat breeders are faced with the challenge of developing improved cultivars at a time when yield gains are stagnating due to increased pest and disease stresses and extreme weather patterns linked to climate change. New technologies and novel selection strategies must be developed and deployed to accelerate genetic gain.
Standing Strong: Maximizing yield potential by optimizing stem strength and biomass partitioning
Little is known about how stem properties such as strength, diameter, wall wall width and height contribute to standability and few markers exist to select for preferred traits. This project will identify, dissect, and prioritize traits that contribute to maximum standability and harvest index in different environments in Manitoba and Saskatchewan.
Optimizing pre-harvest sprouting tolerance in malting barley
This project will produce information for breeders that will help optimize grain dormancy and maintain malting and storage quality, while allowing good seed germination.
Integrated strategies for fusarium head blight management in spring wheat in Manitoba
The intention of this proposal is to identify the most environmentally friendly and cost-efficient integrated disease management approach to recommend for implementation by wheat growers.
Enhancing fusarium head blight research capacity to reduce mycotoxin contamination in wheat
Support further development of Fusarium Head Blight resistance cultivars for all public breeding programs in western Canada through enhancement of FHB screening capacity. Under moderate to severe epidemics, moderate resistance is not sufficient to prevent significant losses. Similarly, available fungicides act to suppress FHB but do not provide adequate control under moderate to severe epidemic conditions.
Transcript abundance in two-row malting barley on interaction with fusarium graminearum chemotypes.
Understanding genetic differences toward disease resistance and reduced toxicity will be useful in long-term plant breeding.
Characterizing the fusarium species that affect major crops in Manitoba
Background
There are indications of the presence of Fusarium graminearum in soybean and pea fields, which represents a threat not only to soybean and pea, but also to cereals. The project will generate information that may provide hints regarding proper crop rotations that involve cereals and soybeans/pulses. Continuously assessing the activity of the Fusarium species found in the crops cited above is crucial in monitoring the threats they represent to the crops, the growers, and the industry in general.
Objectives
Investigate the;
- Cross-pathogenicity between the Fusarium strains infecting soybean and those infecting wheat, barley, and oat;
- Competitiveness of Fusarium species isolated from both pea/soybean and cereals;
- Toxin producing potential of the F. graminearum isolates from soybean versus from cereals;
- Genetic diversity of selected Fusarium species infecting these crops.
Key Findings:
The tested Fusarium strains that can infect wheat/barley/oat and cause Fusarium Head Blight can also infect soybean and cause root rot symptoms.
