A Multi-omics approach for genetic and molecular analysis of clubroot resistance in Brassica napus canola
DownloadFall 2023
Clubroot disease, caused by Plasmodiophora brassicae, is a significant threat to canola production. Growing of clubroot resistant canola cultivars is the most efficient and environment-friendly way of managing this disease. The evolution of new pathotypes eroded some of the resistance available...

Abiotic and biotic factors influencing host-plant use of a generalist herbivore through plant-mediated interactions: oviposition and larval performance by the bertha armyworm, Mamestra configurata Walker (Lepidoptera: Noctuidae) on canola
DownloadFall 2018
The bertha armyworm (BAW), Mamestra configurata Walker (Lepidoptera: Noctuidae), is a native, polyphagous herbivore which feeds on a variety of plants in different families. In the Prairie Provinces, canola, Brassica napus L. (Brassicaceae), is a preferred host, making BAW a significant pest....

Fall 2024
Clubroot, caused by the soilborne pathogen Plasmodiophora brassicae, is a serious disease threatening the production of canola (Brassica napus) in Canada. This project explored various management options for clubroot, including fungicide application, fall and spring liming, and genetic...

Fusarium root rot of canola (Brassica napus): Occurrence, pathogenicity and yield losses in Alberta, Canada
DownloadSpring 2024
Root rot is a soilborne disease of canola (Brassica napus) caused by a pathogen complex. Canola crops were surveyed in Alberta, Canada, in 2021 and 2022 to assess the composition and diversity of fungi associated with root rot in this region. Isolates were identified to genus and/or species based...

Nallanthighal, Sumedha Vaishnavi
As the global population approaches 10 billion by 2050, sustainable food production faces unprecedented challenges. Nitrogen (N) fertilizers, crucial for crop yields, contribute significantly to agricultural greenhouse gas emissions and environmental degradation. The 4R Nutrient Stewardship...

Identifying superior photosynthetic efficiency traits in canola (Brassica napus L.) germplasm
DownloadFall 2024
Canada is the world’s largest producer of canola (Brassica napus), contributing 54% of global production in 2021. However, Canada’s canola yield is not growing at the required pace to reach the targets and compete with other canola producers. To address this issue, multifaceted approaches must be...

Spring 2022
Clubroot, caused by the soilborne pathogen Plasmodiophora brassicae, is a threat to cruciferous crops worldwide and an important disease of canola (Brassica napus L.) in Canada. At present, pathotypes of P. brassicae are distinguished phenotypically based on their virulence patterns on host...

Oat, pea, and canola intercropping: An investigation of the agronomic benefits and underlying biological mechanisms of a multi-crop forage system
DownloadSpring 2022
Oat, pea, and canola intercropping can provide benefits in terms of beef cattle forage as it can provide stable biomass and nutritional yield. Two underlying mechanisms were examined as potential explanations to its stability: 1) plant water use efficiency, and 2) arbuscular mycorrhizal fungi...

Pathotypes of Plasmodiophora brassicae from clubroot resistant canola and assessment of amisulbrom for clubroot control
DownloadSpring 2021
Clubroot, caused by Plasmodiophora brassicae Woronin, is an important soilborne disease of canola (oilseed rape; Brassica napus L.). In Canada, clubroot management relies heavily on the planting of resistant cultivars, but since 2013, resistance has been broken in an increasing number of fields....

Price Transmission in Petroleum Markets and Potential Feedstock Supply for Low-carbon Fuel Production: Implications for Emerging Energy Sources
DownloadFall 2021
Low-carbon fuels are receiving increasing attention from governments worldwide as sustainable alternatives to fossil fuels. But prospects for these emerging industries are uncertain due to several economic barriers. This thesis presents two studies, each investigating a key factor influencing the...
