Flea beetles are the most economically-damaging pest of canola. Researchers at Agriculture and Agri-Food Canada initiated a project to develop canola lines with superior resistance to the crucifer flea beetle by enhancing a natural insect control system.
Parkin: Development of a Germplasm Resource to Dissect Complex Traits in Brassica Napus
Modern canola varieties are derived from a relatively small subset of the genetic diversity found within available collections of Brassica napus germplasm. Intensive selection for specific quality traits has further narrowed the genetic diversity within elite breeding lines.
Bonham-Smith: Genomics of Clubroot Disease Development in Canola and Development of in planta RNAi to Impart Novel Resistance
Clubroot, resulting from an infection by Plasmodiophora brassicae is a devastating disease of canola. Researchers initiated a five-year study in 2010 to investigate the cellular and molecular mechanisms of P. brassicae infection, and to develop molecular markers and tools for utilizing pathogen protein targets for improved resistance to clubroot disease in canola.
Peng: Characterization and Utilization of Newly Identified Resistance Sources for Sustainable Clubroot Control on Canola
Clubroot, caused by the pathogen Plasmodiophora brassicae (Pb) can be a devastating disease to canola crops. Since 2009, resistant canola cultivars have been available in Canada but all of them are based on a single dominant R gene.
Borhan: Identifying Virulence Factors in Leptosphaeria maculans, the Cause of Blackleg Disease of Canola
Researchers in Saskatchewan conducted a three-year project to identify virulence genes in the Leptosphaeria maculans genome, the pathogen that causes blackleg in canola.
Borhan: Improving the Durability of Resistance to Blackleg in Brassica Napus Using the Novel LepR4 Gene
Developing genetically resistant canola varieties is the best and only effective method for controlling blackleg to date. Researchers at Agriculture and Agri-Food Canada have been able to locate the resistance gene LepR4 and develop DNA based markers in close proximity to this gene.
Buchwaldt: Development of Sclerotinia Resistant Brassica Napus Lines and Molecular Markers for Marker-Assisted Breeding
Sclerotinia stem rot is one of the major diseases affecting canola production. New varieties of Brassica napus canola with improved levels of sclerotinia resistance are required as part of an integrated management strategy.
Roslinsky: Transfer of Pod Shatter Resistance from Yellow Seeded B. Napus and B. Napus to Canola
Although the majority of canola producers currently swath Brassica napus prior to combining, many producers would prefer to have the option to straight combine and therefore avoid the cost and time associated with swathing.
Selvaraj: Building Durable Clubroot Resistance in Canola: Identification of Multiple Clubroot Resistance Genes From Brassica Napus and B. Rapa for Marker-Assisted Gene Stacking in Canola Breeding
Clubroot is a serious soil-borne disease of canola caused by the pathogen Plasmodiophora brassicae. Multiple genes that can be clearly identified and stacked or rotated are required for long-term effectiveness of clubroot management toward protecting canola yield.
Sawhney: Regulation of Male Sterility in Canola for Use in Hybrid Seed Production
Researchers at the University of Saskatchewan initiated a study in 2000 to develop a non-transgenic, GMS system in canola (Brassica napus) using chemicals to restore fertility.
Buchwaldt: Evaluation of sclerotinia resistance in Canadian canola cultivars and identification of resistant Brassica napus germplasm held at Plant Gene Resources of Canada (Copy)
Sclerotinia stem rot, caused by Sclerotinia sclerotiorum, is a disease problem of canola world wide causing serious yield losses especially under wet weather conditions. Sclerotinia resistance has been a long-time goal of canola breeders and producers.
Hegedus: A Genomics Approach to Sclerotinia Resistance in Brassica napus
Sclerotinia stem rot, caused by Sclerotinia sclerotiorum, is a serious disease problem of canola worldwide. The long term objective for researchers at Agriculture and Agri-Food Canada is to provide the canola industry with specific resistance genes and molecular markers as a selection tool used by plant breeders for selection of stem rot resistant canola cultivars.
Roslinsky: Pod Shatter Resistant Canola
Researchers are using standard molecular biology protocols to generate a genetic framework map and to try to develop lines that include genetic control of pod shatter.
Lange: Marker-Assisted Breeding for Fusarium Wilt Resistance in Canola
Fusarium wilt resistance in Brassica napus was found to be conferred by a single dominant gene, the A-genome. This means that B. rapa and B. oleracea may be sources of resistance to fusarium wilt available to B. napus breeders.
Falk: Developing High Yielding Brassica Rapa Cultivars With Resistance to Brown Girdling Root Rot, Blackleg, White Rust, and Clubroot
The development of early maturing canola is crucial to the northern canola growing areas of western Canada. Although B. rapa has several advantages over B. napus, producers currently have very few cultivars from which to choose, and only one with resistance to blackleg.
Kutcher: Optimizing Canola Production, Pest Implications of Intensive Canola Rotations
Flexibility in rotation planning allows canola and field pea producers to adapt to changing management practices and marketing opportunities. Current recommendations are to follow a one in four year rotation for canola or field pea on a particular field.
