Winter wheat has an advantage over spring varieties as it yields higher (25%), uses spring moisture more efficiently and reduces soil erosion by providing ground cover during the fall and early spring. Rapid initial spring growth of winter wheat allows it to out-compete weeds and escape peak of Fusarium head blight infections by flowering early. However, Canadian prairie producers require winter wheat with increased cold hardiness and improved winter survival to provide adequate insurance against losses due to sudden cold snaps during winter and spring.

冬小麦比春小麦具有优势，因为它产量更高（25%），更有效地利用春季水分，并通过在秋季和早春提供地面覆盖来减少土壤侵蚀。冬小麦在春季初期的快速生长使其能够通过提早开花来战胜杂草并逃避赤霉病的感染高峰。然而，加拿大大草原生产者要求冬小麦具有更强的抗寒性和更好的冬季生存能力，以提供足够的保险，防止冬季和春季突然寒流造成的损失。
