The 1993 Uniform Regional Hard Red Spring Wheat Performance Nursery was planted 
 at 22 locations and harvested at all locations in Minnesota, North Dakota, South 
 Dakota, Montana, Idaho, Wyoming, Wisconsin, Washington, and Canada (Table 1). 
 The nursery contained 32 entries, 5 checks (4 tall, 1 semidwarf) and 27 
 experimentals including two sawfly resistant lines. Trials were conducted as 
 randomized complete blocks with 3 replicates. Yield data obtained from Prosper, 
 Redfield, Powell, Madison and Swift Current were not used in any of the over 
 location averages nor the stability parameter analysis. Data from each of 22 
 locations are given in Tables 2-1 to 2-22.
 The highest average yielding location was Aberdeen, Idaho with 109 bu/A and the 
 lowest location yield was 7.5 bu/A at Redfield, South Dakota. The average yield 
 of all locations was 50 bu/A and seven experimentals were in the first LSD unit 
 (5.5 bu/A) from the best yielding entry. Eight locations with acceptable C.V.1s 
 with scab epidemics were summarized in Table 2-24. The average yield of these 
 locations was 40 bu/A. The LSD was 6.2 bu/A and nine experimental were in the 
 top LSD group. Table 2-25 are the locations not reporting scab. The LSD was 7.7 
 bu/A and seven experimentals were in the first LSD group. Drastic switches 
 occurred among the entries with the exception of N90-0671 and SDO005 which 
 appeared in both. N86-0348, XW398A4, MN90114, SBE0444, and SBE0437 appear in the 
 non-scab table but were not in the first LSD unit in the scab locations. SD8070, 
 N90-0666, SDO010, ND671, SD8073 and SD8072 all appeared in the scab locations 
 but not the nonscab.
 Six entries were tied for earliest to head at 30 days after June 1, while Era 
 was latest to head at 37 days. Experimentals with the highest test weight were 
 ND674, ND671, and SD8070. Data for experimentals and checks grown for two years 
 are given in Table 3-1. XW398A4, N86-0348, SD8073, SD8072, SD8070, and Butte 86 
 were in the first LSD unit. ND671, SD8070, SD8072, and Butte 86 had test weights 
 of 59 lb/bu or better.
 Stability parameters for entries in 1993 are given in Table 3-2. Compared to 
 other years, deviations from regression were considerably greater than normal. 
 Scab obviously affected these results by causing much greater deviation from 
 linearity. Experimentals with deviations of 170 or less were N88-3140, 8601AE3C, 
 ND673, ND671, MN90253, and ND678.
 Greenhouse seedling and adult plant field reactions to stem and leaf rust are 
 shown in Tables 4-1 to 4-3, and Fusarium head blight from field inoculation is 
 given in Table 4-4.
