ADDITIONAL FIELD DATA 
In addition to the information tabulated above on susceptibility of 
varieties in the rust nursery at Corvallis, Oreg., during the three seasons, 
many valuable field notes were recorded at various times and places where 
rust infection had developed under natural conditions. 
At the Sherman County Branch Station, at Moro, Oreg., where exten¬ 
sive sowings of wheat varieties are made each year, there was a severe 
outbreak of stripe rust in the spring of 1919. This afforded an excellent 
opportunity to obtain data on the comparative susceptibility of some of 
the leading varieties of wheat grown at that station in 1919. The follow¬ 
ing table shows the ratings of these varieties, using the system of grading 
explained for Tables III and IV. The notes, taken just before the plants 
headed, are recorded in Table V.

During the season of 1919 notes were taken also on the stripe rust 
occurring on a number of wheat varieties growing at Moscow in the 
plots of the agronomy department of the University of Idaho. The notes 
were taken on June 20, when the grain was mostly headed. Apparently 
the rust was just beginning to appear at that time and, as no opportu¬ 
nity presented itself to inspect this grain again, it is not known that the 
figures in Table VI represent the maximum rust infection which ap¬ 
peared on these plots during that season. At any rate, they give some 
indication of the most susceptible varieties.
