Optimizing crop rotations to enhance agronomic, economic and environmental performance

mca2022dev on March 14, 2023

This project aims to generate research-based information to support on-farm agronomic and farm management decisions by determining the effect of including soybean and field pea in Manitoba cropping systems on crop productivity and quality, diseases, soil health, nutrient cycling, and economic risk and return. The production and economic information gleaned from this project will also be used to investigate the effects of different rotation strategies on energy and resource use efficiency and to determine the environmental footprint of various rotations, in order to assist in addressing the broader issues now facing agriculture of how crop production strategies and more diverse rotations might influence and address climate change concerns.

Genetic Analysis and genomic selection models for leaf rust resistance in western Canadian winter wheat

mca2022dev on March 14, 2023

This project seeks to address this current lack of information regarding leaf rust resistance in western Canadian winter wheat. The data from this project will be used in
two types of analyses: (1) genome-wide association study (GWAS) and (2) genomic selection (GS). GWAS will identify specific DNA markers and/or DNA marker haplotypes highly correlated with individual leaf rust resistance genes. GS utilizes DNA markers spanning all wheat chromosomes to predict leaf rust resistance in breeding lines.

Pneumatic air seeder simulation

mca2022dev on March 14, 2023

Within the scope of this proposal, PAMI will simulate wheat in air seeders through the development of a coupled fluid-particle (CFD/DEM) model. This modeling approach connects the airflow patterns within the air seeder system to the movement of wheat particles through it. Insights from this research will help producers to better understand seed distribution inconsistency when seeding wheat, as related to producer-influence operating variables like air flow and grain feed rates, and air seeder hose geometry. The work to be completed within this scope will be entirely computer simulation, no physical testing will be required.

Accelerated breeding strategy for flax improvement

mca2022dev on March 14, 2023

This project will adapt “speed breeding” protocols developed for other crops and apply them to flax breeding for the development of populations ready for pre-registration trials as well as populations suitable for genetic mapping and trait analysis. Significant time savings will be realized by reducing the time required to produce both pre-registration lines and mapping populations.

Enhancing capacity of barley breeding programs in western canada: establishing disease nurseries and a pre-breeding platform

mca2022dev on March 14, 2023

Diseases are one of the biggest foes associated with barley production in Canada; Fusarium head blight (FHB) in particular is the most dangerous as it produces mycotoxin in the grain thus affecting malting and marketing. This project has multi-faceted benefits to SK and Canadian barley industry. The proposal will enhance disease screening capacity of three public barley breeders i.e. Drs. Beattie (SK), Badea (MB), Capettini (AB) for their early and advanced barley breeding material.

Understanding auxinic herbicide resistance in kochia and staying ahead of what’s next

mca2022dev on March 14, 2023

The proposed research will help farmers and agricultural industry understand which herbicide active ingredients and usage scenarios remain effective for management of multiple-HR kochia. It will also help them understand how auxinic herbicide resistance in kochia is inherited, how quickly it will spread, and what can be done to mitigate this spread. This work will also develop a new surveillance program to stay ahead of PPO inhibitor resistance in Canadian kochia populations.
