1999 North Dakota Hard Red Winter Wheat
Variety Selection Guide
Compiled by: Dr. Michael D. Peel, Extension Agronomist
Hard red winter wheat varieties adapted for production in North Dakota are described in the following tables. Successful winter wheat production depends on numerous factors including selecting the right variety for a particular area. The information included in this publication is meant to aid in selecting that variety or group of varieties. Characteristics to evaluate in selecting a variety are: yield potential in your area; protein content when grown with proper fertility; straw strength and plant height; reaction to important diseases; and maturity.
The recommended seeding dates for winter wheat are September 10 to September 30 south ND highway 200 and September 1 to September 15 in northern regions. Planting after the recommended dates reduces winter survival and grain yields. Planting prior to the recommended date unnecessarily depletes soil moisture reserves, increases risk of disease and may reduce winter survival.
Winter wheat should be seeded at a rate of 1,000,000 viable seeds per acre or about 80 pounds per acre. Higher seeding rates are suggested for late seeding or for poor seedbed conditions. Only the most winterhardy varieties available should be considered when growing winter wheat in North Dakota. Of the current varieties, Roughrider, Agassiz, Seward, Elkhorn, Ransom and Crimson possess the best combination of winterhardiness and yield. When wheat streak mosaic virus is a concern Crimson should be grown, of the varieties adapted to North Dakota it has the best tolerance.
Phosphorus aids overwinter survival by stimulating root growth and fall tillering. The secondary root system that develops with tillering is essential for a healthy deep-rooted plant capable of withstanding stress. If winter wheat is planted on bare soil an application of phosphorus is essential. While important, the contribution of phosphorus to overwinter survival is secondary to varietal hardiness.
When selecting a top yielding variety it is best to use data that summarizes several years and locations. The notion that the single data set nearest your farm will indicate which variety will perform the best for you is incorrect. Choose the variety that on average performs the best at multiple locations near you over several years.
