The updated K-State Wheat Variety Guide is now published!
This has information on the agronomic characteristics and disease ratings for the wheat varieties for our area.
The charts to compare between varieties are on pages 17-20.
You will find:
  • Results from the county demonstration plots for Cheyenne Co (Hingst Farm), Sherman Co (F&J Farms), Wallace County (E&H Farms), and Wallace County (Mai Farms). These are large strip plots, with each variety in the plot one time.
  • Results from the K-State wheat performance tests for Thomas Co, Greeley County and Decatur County. These tests have each variety replicated 5 or 6 times.
  • Results from the Colorado State University performance tests, with dryland results from Akron and irrigated results from Burlington.
You can also see wheat samples from the plots in the display booth at your county fairs in Cheyenne, Sherman and Wallace Counties.
For a complete listing of the sessions, with handouts and recordings, follow the link above.

This guide has ratings for tolerance and susceptibility of varieties to several diseases. Pages 17-18 are a summary table, to make it easier to look up several varieties. Most varieties commonly planted in western Kansas are fairly susceptible to fusasium head blight, but be sure to check your varieties.
