Freezing stress is the main obstacle affecting the geographical distribution, growth, development, quality, and productivity of rapeseed ( Brassica napus ) in northern China. However, there is a little knowledge of rapeseed freezing tolerance mechanism. Here, 289 core germplasms collected from 36 co...
