The 1997 Uniform Regional Hard Red Spring Wheat Performance Nursery was
 planted at 18 locations and harvested at all locations in Minnesota. North
 Dakota. South Dakota. Montana. Wyoming, Wisconsin, Washington. and Canada
 (Table 1). The nursery contained 219 entries and 5 checks. Trials were
 conducted as randomized complete blocks with three replicates. The Winnipeg
 nursery was grown in Portage la Prairie. Manitoba. with rust data from
 Morden. Manitoba. Yield data obtained from Morris, Minnesota, Powell.
 Wyoming: and Swift Current. Canada were not used in any of the over
 location averages nor in the stability parameter analysis. Data from each
 of 18 locations are given in Tables 2-1 to 2-18.
 The highest average yielding location was Bozeman, MT, with 87 bu/A 
 and the lowest yielding location was 17 bu/A at Williston, North Dakota. 
 The average yield of 15 locations combined was 46 bu/A, with MN9341 3, 
 ND691 and N93-0136 in the first LSD unit.  Two entries, SD3249 and SD3310,
 were earliest to head at 24 days after June 1,while TX92U2317 was latest 
 to head at 32 days. The entries within the first LSD unit for test
 weight were SD3249, Sharpshooter, SD3310, and ND694. Data for 
 experimentals and checks grown for two years are given in Table 3-2. 
 MN93413 and SBE0050 were in the first LSD unit for grain yield. The
 highest test weight entries was SD3249, at 61.8 lb/bu.
 Stability parameters for entries in 1997 are given in Table 3-2. A lower 
 b value indicates less responsiveness to changing environments for yield.
 A high Msq indicates lower predictability for yield and should be a 
 warning that individual locations caused major deviation from expected 
 performance caused by either disease or agronomic problems.
 Adult plant field reactions to stem and leaf rust are shown in Tables 4-1
 through 4-2. Scab reaction from field inoculation in Minnesota is given 
 in Table 4-3. Leaf spotting and scab reaction at Langdon, ND is given in 
 Table 4-4.
