Winter Rapeseed Evaluations in North Dakota

Production risk with winter annual crops especially in regions with severe winters include poor spring stands due to winter-kill. Previous evaluations of winter rapeseed (Brassica napus L.) in North Dakota during the mid 1980s indicated inadequate winter-hardiness and essentially zero plant survival. However, more recently developed cultivars offer greater winter-hardiness and the potential for good crop performance from over-wintering stands.
