Flowering time is crucial for canola breeding as it helps reduce heat stress and better utilize soil moisture, involving the internal circadian clock of plants.
The study used canola varieties 'Westar' and 'Surpass 400' to create a chromosome segment substitution line (CSSL) that contained a segment delaying flowering significantly compared to 'Westar.'
Four introgression lines (ILs) showed delayed flowering, indicating partial dominance in flowering time traits, and the flowering time locus was mapped to a 1 Mb region on chromosome A10.
Stripe rust, caused by Puccinia striiformis f. sp. tritici, has been an important disease of winter wheat (Triticum aestivum) in the eastern United States since 2000, when a new strain of the pathogen emerged.
