Science Edition 2022—CRISPR technology was used to generate a range of starch branching enzyme (SBE) mutants in canola. Sbe quadruple and sextuple mutants were used for expressing maize endosperm SBEI and effects on growth, morphology, flowering and yield determined. Introduction of corn SBEI into quadruple mutants (four canola genes edited) repeatedly led to increased total seed yield...

Science Edition 2022—AAFC researchers completed the genetic mapping of blackleg resistance gene Rlm11. Rlm11 is effective against L. maculans isolates carrying the avirulence gene AvrLm11, which is found in 95 per cent of L. maculans isolates collected from Western Canadian canola farms. Canola lines with Rlm11 will enable canola farmers to effectively control the blackleg disease. “Introgression...

Science Edition 2022—Canola lines with a broad spectrum of clubroot resistance were developed, which are valuable for developing resistant cultivars by canola breeders. Additional developments can improve the ability to monitor changes in the clubroot pathogen race structure, as the pathogen evolves in canola fields on the Prairies. “Defining populations of P. brassicae with near isogenic B....
