Trial Description and Summary
 
 The 1979 Uniform Regional Hard Red Spring Wheat Performance Nursery (URHRSWPN) was 
 planted at 23 locations and harvested at 22 in Minnesota, North Dakota, South Dakota, 
 Montana, Idaho, Wyoming, Wisconsin, Washington, Nebraska, and Canada (Table 1). The nursery 
 contained 28 wheat entries, 5 checks (4 tall and 1 semidwarf) and 23 experimentals (8 tall 
 and 15 semidwarf). Yield data obtained from Winnipeg, Redfield, Mead and Torrington were not 
 used in the overall average. Data from 22 stations are given in Tables 2-1 to 2-22.
 
 The average yields at the three irrigated stations, Carrington, North Dakota; Aberdeen, 
 Idaho; and Bozeman, Montana, were 59.9, 63.3, and 83.0 bu/A respectively. For the entries 
 grown at the non-irrigated stations, the highest average yield was 71 bu/A at Langdon, North 
 Dakota, while the lowest average yield was 25.1 bu/A at Havre, Montana, and Dickinson, North 
 Dakota.
 
 Miscellaneous agronomic and disease data are summarized in Table 2-23. Entries 
 NHS74183, Butte, ND567, and ND570 headed 40 days after June 1 while WA6511 headed 48 days 
 after June 1. The maturity range was between 89 to 94 days.
 
 The average yield and bushel weight data of all individual entries for 1979, 1978-79, 
 and 1977-79 are shown in Table 3.
 
 Seven wheats exceeded Era in 1979. In 1978-79, NHS751001, MN7336, MN7222, and MN7378 
 exceeded Era and NHS74183 was equal to Era. Butte was the highest yielding normal height in 
 1979 followed by ND565, ND570, and SD2355.  ND550 was the highest yielding normal height line 
 in 1978-79 and 1977-79. ND567, Butte, ND550, and SD2256 were high test weight lines in 1979. 
 ND550 is the highest test weight line in 1978-79 and 1977-79.
 
 Seedling reactions to stem rust are given in Table 4-1. Adult field reactions to stem 
 and leaf rust are shown in Table 4-2 and 4-3, respectively.
