Identification and genetic mapping of resistance genes against Canadian pathotypes of Plasmodiophora brassicae in Brassica rapa and Brassica napus
DownloadFall 2022
Clubroot (Plasmodiophora brassicae) is an important disease of canola/rapeseed (Brassica napus) and other crucifers. In this study, resistance loci/genes effective against P. brassicae pathotypes 2B, 3A, 3D, 3H, 5C, 5X and 8J were identified and mapped via genotyping-by-sequencing, QTL analysis,...

Improving Verticillium longisporum inoculation protocols and quantifying canola yield losses
DownloadSpring 2024
Verticillium stripe, caused by Verticillium longisporum, is an emerging soilborne disease of the Canadian canola (Brassica napus) crop. This study aimed to refine techniques for inoculating the pathogen on canola and to quantify its impact on hybrid canola yield under greenhouse and field...

Assessing spider (Araneae) diversity and pitfall trap retention in canola (Brassica napus L.) agroecosystems in north-central Alberta, Canada
DownloadFall 2024
Little is understood about the role of spiders (Araneae), their community composition, and predator-prey interactions in canola agroecosystems. Understanding these relationships may inform management decisions to effectively use spiders as biological control agents against insect pests. In...

Factors Influencing Verticillium Stripe in Canola: Blackleg Interaction, Host Resistance, and pH
DownloadFall 2024
Verticillium stripe, caused by Verticillium longisporum, is emerging as an important disease of canola (Brassica napus) in Canada. This thesis aimed to enhance understanding of potential interactions between Verticillium stripe and blackleg (Leptosphaeria maculans), assess the influence of pH on...

Biomass partitioning in canola (Brassica napus) and the characterization of leaf anatomical structures
DownloadFall 2024
Canola is the predominant crop grown on the Canadian Prairies, contributing about $26.7 billion to the economic activities per year in Canada. In 2023, Canada produced approximately 18.3 million tonnes of canola; however, the Canola Council of Canada set a goal of producing 26 million tonnes by...

Lab-on-a-Chip Designs for Airborne Spore Detection: Towards the Forecasting of Sclerotinia Stem Rot of Canola
DownloadFall 2022
Sclerotinia stem rot (SSR), caused by the necrotrophic fungal pathogen Sclerotinia sclerotiorum, is one of the most devastating diseases affecting crops. More than 400 plant species around the globe are affected by this fungus. In canola, one of Canada’s most important crops, yield losses due to...

Spring 2018
MicroRNAs (miRNAs) are small non-coding RNAs, which are known to regulate plant responses to abiotic stresses, such as Cold Stress (CS) and during normal growth and development. In Brassica napus (canola), miRNAs regulate various developmental processes and responses to metal stress however;...

Evaluation of Genetic Diversity and Performance of the Inbred Lines Derived from B. Napus x B. Rapa Interspecific Crosses and Their Test Hybrids
DownloadSpring 2018
ABSTRACTSpring Brassica napus L. canola (AACC, 2n = 38) is the second most important crop in Canada. Genetic diversity in this crop is narrow; therefore, broadening of the genetic base of this crop is needed for continued improvement through breeding. For this, the exotic gene pools of this...

Monitoring Airborne Inoculum of Sclerotinia sclerotiorum at Canola Flowering and Relationships to Weather Conditions and Disease Incidence and Severity
DownloadFall 2022
Sclerotinia stem rot, caused by Sclerotinia sclerotiorum, is an important disease of canola (Brassica napus). Disease development is highly dependent on weather conditions and is initiated by infection of the petals by airborne ascospores, followed by mycelial progression into leaf and stem...

Grounding global seeds: a contextual comparison of the politico-ecological implications of genetically modified crops for farming communities in Alberta (Canada) and Andhra Pradesh (India)
DownloadFall 2010
The main objective of my dissertation is to analyze and compare the socio-ecological implications of the adoption of genetically modified (GM) seeds and alternative agroecological farming methods for farming communities in Alberta, Canada and Andhra Pradesh, India – localities situated in...
