TRIAL DESCRIPTION AND SUMMARY
 
 The 1985 Uniform Regional Hard Red Spring Wheat Performance Nursery *URHRSWPN was planted 
 and harvested at 22 locations in Minnesota, North Dakota, South Dakota, Montana, Idaho, 
 Wyoming, Wisconsin, Washington, Nebraska, and Canada (Table 1). The nursery contained 30 
 entries, 5 checks (4 tall, 1 semidwarf), 1 hybrid (RH841246), and 24 experimentals (4 
 talls and 20 semidwarfs). Yield data obtained from Bozeman and Tetonia were not used in 
 the overall average. Data from 22 stations are given in Tables 2-1 to 2-23.
 
 For entries grown at the stations, the highest average yield was 98 bu/A at Winnipeg, 
 Canada, while the lowest average yield was 15 bu/A at Havre, Montana.
 
 Entry SD8026 headed 18 days after June 1 while Era and Marquis headed 25 days after June 
 1. The average yield and bushel weight data of all entries for 1985, 1984-85, and 1983-85 
 are shown in Table 3-1. Nineteen wheats exceeded Butte in 1985 and 10 exceeded Era, the 
 highest yielding check. SD2956, SD2968, and MN82128 were the highest yielding entries in 
 1984-85 while ND597 was the highest yielding entry in 1983-85. Five entries exceeded 60 
 lb/bu in 1985: SD8036, Butte, MN80056, HS82-175 and SD2962. The highest test weight lines 
 in 1984-85 were SD8036, Butte and MN80056 and in 1983-85 was Butte.
 
 Stability parameters for entries in 1985 and percent of times the line appeared in the 
 top five entries at each location are given in Table 3-2. Two lines with very large 
 deviations from regression were WA7182 and SD8026. RE841246 appeared in the top 5 89% of 
 the time while HS82-175 appeared in the top 5, 68% of the time. Two other lines appeared 
 in the top 5, over 40% of the time, SD2956 and MN82047. Adult field reactions to stem and 
 leaf rust are shown in tables 4-1 and 4-2, respectively.
