 The list above shows the pedigree, selection number and the year a variety or 
 selection was first entered in the uniform test. Eleven of the twenty entries 
 grown in this nursery were semidwarfs. Data from 21 stations are given in Tables 
 1-1 to 1-21. The average yield at the two irrigated stations, Bozeman and 
 Carrington, was 53.7 and 62.4 Bu/A, respectively. For the entries grown at the 
 non-irrigated stations, the highest average yield was 80.1 Bu/A at Langdon, 
 North Dakota, while the lowest average yield was 19.9 Bu/A at Lind, Washington.
 Average yields and bushel weights in 1971 and for the two-year period 1970-71 
 for entries in this nursery are shown in Table 2. Ten of the eleven semidwarf 
 selections ranked above the check variety Chris. For the third year in a row, 
 Era ranked first with 50.1 Bu/A, while Chris yielded 38.1 Bu/A. NK70Y14 had the best 
 bushel weight with 61.1 Lbs/Bu followed by Bounty 208 and Era with 60.8 and 60.7 
 Lbs/Bu, respectively.
 Miscellaneous agronomic and disease data are summarized in Table 3. World 
 Seeds 1809 headed 5 days earlier than Chris, while Fletcher and Era were 2 days 
 later than Chris. The varieties World Seeds 1809, ND506, Bounty 208, 
 H678-1-6-9, Lark, NK70YI4 were the first to mature, having a similar value of 
 102 days, while Fletcher was the last with 108 days. The semidwarfs were about 
 15-20 cms shorter than the standard check varieties.
 Era, Fletcher, WIS271 and Lark possess very good shattering resistance. 
 The entry ND497 had the best 1000 K. weight with 46.5 gms, while Chris was 
 lowest with 35.0 gms.
 Adult field reactions to leaf and stem rust are given in Table 4-1. 
 Seedling reactions to stem rust are shown in Table 4-2. Stem rust was 
 relatively scarce in the spring wheat region in 1971. All of the varieties, 
 with the exception of Marquis, had adequate resistance. We are beginning to see 
 some evidence of a shift in the leaf rust races since varieties like Chris, 
 Polk, Fletcher and others are being attacked to a greater degree each year. 
 Although the resistance was adequate in the commercial fields for this year, 
 there is concern that the Frontana resistance will not be useful in future 
 Ergot appears to be a very serious disease in Waldron. We have observed 
 that as the acreage of Waldron has increased, so has the incidence of the
