Abstract:

Understanding and manipulating the variation for various traits involved in adaptation is essential for sustainable production of canola in diverse environments. We investigated the naturally-occurring variation in flowering time, resistance to blackleg and pod shattering, tolerance to manganese, fractional ground cover, carbon isotope discrimination, water soluble carbohydrate accumulation, and grain yield across diverse growing environments to gain insight of the genetic architecture for these traits. Through extensive phenotyping and genetic analysis, we have untangled genomic regions associated with these traits. We are now developing improved pre-breeding germplasm by combining different genomic regions for stable canola production.
