Many challenges still present themselves when growing canola due to diverse environmental conditions which can be contributed to little genetic diversity from the Brassica napus germplasm.
Develop a foundational resource for canola crop improvement: a nested association mapping (NAM) population for spring type B.napus that will target adaptation to Prairie conditions.
Composed a NAM population of 2500 recombinant inbred lines, in addition to phenotyping parental lines and their progeny which provided a detailed picture of their genetic composition.
This knowledge will be used to analyze the introduction of traits such drought and heat stress, root-soil interactions, seed dormancy and verticillium resistance into commercially available canola varieties.
