Xiaoyun,a model accession for functional genomics research in Brassica napus

Dear Editor,Rapeseed(Brassica napus)provides quality edible plant oil and industrial raw materials,as well as protein-rich animal feed;however,molecular characterization of functional genes in rapeseed remains challenging,largely owing to its complex polyploid genome,relatively long generation time,and environmentally sensitive traits.To accelerate functional genomics research on rapeseed,especially in an artificially controlled,stable environment like that of comprehensive speed breeding(CSB;Song et al.,2022),we screened out the representative B.napus accession Xiaoyun(小芸),with a rapid cycling time and scaleddown but normal plant architecture.
