Low nitrogen (LN) stress is a major limiting factor affecting crop growth and productivity. Understanding the genetic basis of LN tolerance is essential for improving nitrogen use efficiency in Brassica napus. A genome-wide association study (GWAS) was conducted on a panel of 275 B. napus accessions...
