Plant-microbe Interactions to Overcome the Negative Effects of Stress and Enhance Canola Yields
Plant-microbe Interactions to Overcome the Negative Effects of Stress and Enhance Canola Yields
The overall objective of this work is to determine the utility of the microbe-to-plant signal compound thuricin 17 in mitigating stress effects on canola.
Within this overall objective there are 3 specific targeted objectives:
1) Determine the efficacy of thuricin 17 in mitigating low temperature stress effects,
2) Determine the efficacy of thuricin 17 in mitigating drought stress effects,
3) Determine the efficacy of thuricin 17 in mitigating a combination of drought and high temperature stress effects, and
4) Determine the efficacy of thuricin 17 in improving crop yield through stress mitigation under field conditions.
Development of Specialty Canola Germplasm with Clubroot Resistance for Eastern Canada – A and B
Development of Specialty Canola Germplasm with Clubroot Resistance for Eastern Canada – A and B
Objectives:
Continue the development of AAFC specialty canola germplasm with clubroot resistance and testing of clubroot resistant lines in Eastern Canada by:
1) Pre-registration yield and in-field resistance testing of N99-508CR and YN01-429CR breeding lines with Rcr1 and Rcr2 resistance,
2) Introgression of Rcr3 resistance into N99-508CR and YN01-429CR backgrounds, and
3) Introduction of Rcr1, Rcr2 and Rcr3 into three additional yellow-seeded or low fibre AAFC breeding populations.
Occurrence of Swede Midge and Evaluation of Potential Control Mechanisms in Canola Production in Ontario and Québec
Occurrence of Swede Midge and Evaluation of Potential Control Mechanisms in Canola Production in Ontario and Québec
The overarching goal of this activity is to gain knowledge about the swede midge in Ontario and Quebec and investigate the potential for biological control agents to improve management of this devastating pest of canola. This goal will be achieved through the following specific objectives:
1) Population dynamics of swede midge in different parts of Ontario and Québec
2) Distribution of Synopeas myles parasitoids in canola regions
3) Evaluate the occurrence of other parasitoids in canola regions
4) Study the biology of the parasitoid S. myles and its efficacy against swede midge
5) Survey the presence of new canola flower galling midges
5) Transfer of knowledge to growers and crop consultants
Investigation of Critical Tissue Sulphur Concentration and Nitrogen to Sulphur Ratio for Optimizing Canola Production in Eastern Canada – A and B
Investigation of Critical Tissue Sulphur Concentration and Nitrogen to Sulphur Ratio for Optimizing Canola Production in Eastern Canada – A and B
Objectives:
1) Identify the ranges of canola plant S concentrations and N:S ratios at various growth stages and at maturity.
2) Determine the critical S concentration and N:S ratio at early growth stages in relation to canola yield and NUE.
3) Develop a site-specific S recommendation rate for enhanced nutrient use efficiency and canola yield.
