 Seeded - Langdon, May 1; Carrington, May 5 (flood irrigation); Oakes, May 7; 
 	(overhead irrigation); Minot, April 28; Fargo, May 12.
 
 1 = Comma- Separation of plants into 2 or more reaction classes (segregation or seed mixture)
 Dash -	Range in reaction on each plant or range in severity between plants with the same reactions.
 
 Natural inoculum - Additional inoculations of races 15B and 151 at Fargo. Readings at soft dough to mid dough stages.
 
 2 = Av. C.I.  Average coefficient of infection is the average of the 5 coefficients of infection for each entry. Coefficient of infection 
 for each reading was determined by multiplying percent severity by reaction where resistant (R) = 0.2, moderately resistant (MR) = 0.4, 
 intermediate(M) = 0.6, moderately susceptible (MS) = 0.8 and susceptible (S) = 1.0. When a double reading occurred, only the percent 
 severity and the response preceding the comma or dash was used to determine the coefficient. Trace severity(t)=2.5 percent.
