made on the basis of these correlations it is hoped to develop a new 
variety better adapted than either parent to Montana conditions.

METHODS USED 
Under a cooperative agreement with the Montana Agricultural 
Experiment Station the hybrid material was grown at the three 
stations previously mentioned, these stations being fairly represen- 
tative of nonirrigated conditions in both the intermountain and 
Plains sections for wheat production in Montana. 
Bozeman is located under fairly humid conditions in the Gallatin 
Valley and has a normal annual precipitation of 18.67 inches. Moc-
