They are also excellent choices when seeding date is delayed past October 1. Next there is a group of varieties such as Cardinal, Dynasty, Howell, and an ever increasing number of private company offerings. Variation in disease resistance among these types makes for wider fluctuations in performance from year to year. Make your selections in this category based upon performance at a number of locations and years. Yield information can be obtained from the UW Extension office.
Producers can help spread risk by seeding more than one proven variety each year.
Planting certified seed assures a quality seed source regardless of variety. Optimum planting dates for winter wheat correlate strongly with a variety's degree of winterhardiness. Glacier and Merrimac are less sensitive to planting date. This disease is transmitted by aphids in the fall and no variety carries resistance. It is hard to estimate which years BYDV will be a significant problem.
