Potential for winter wheat production in Saskatchewan

Winter cereal trials consisting of 10 cultivars representing cold hardiness potentials ranging up to the hardiness of Frontier winter rye were seeded at test sites throughout Saskatchewan for 2 yr. At most sites in the Brown soil zone only winter rye survived without extensive winter damage. At sites in the Black and Gray soil zones, winter survival was sufficient to provide agronomic data for several winter wheat cultivars. Considerable yield compensation took place in stands exhibiting partial winterkill, and as a result hardier cultivars did not always demonstrate a yield advantage.
