RESULTS OF THE NURSERY EXPERIMENTS. 
The percentage of stem rust found on the varieties grown in 1915, 
1916, and 1917 and the 3-year average for all varieties grown in all 
three seasons are shown in Table 1. Notes on the quality of grain 
also are given for the years 1916 and 1917. 
.The varieties are arranged according to type and are grouped as_ 
to the characters, winter or spring, awned or awnless, glabrous or 
pubescent glumes, and soft or semihard to hard kernel. All of the 
winter-wheat varieties with the exception of Binkel Club are common 
wheats (Triticum vulgare). The spring grains include varieties of 
common wheat, as well as durum wheat (7. durum), emmer (T. 
dicoccum), and einkorn (7. monococcum). 
The “Identification numbers” include the ‘‘Pedigree number,’’ 
as used by Prof. H. F. Roberts; the ‘‘Kansas number,” which is an 
accession number assigned by the department of agronomy; and 
the C. I. number, used by the Office of Cereal Investigations of the 
Bureau of Plant Industry. 
TaBLE 1.—Stem-rust infection of wheat varieties after artificial inoculation in the nursery 
at Manhattan, Kans., in the years 1915, 1916, and 1917, together with data on kernel 
quality in 1916 and 1917. 
[KEY TO SyMBOLS.—Identification numbers (columns 1 and 3): C.-I.=Cereal Investigations, H=hybrid, 
K=Kansas, P=pedigree. Rust infection (columns 5 to 7): T=trace, Wk=winterkilled. Quality of 
kernels (columns 9 and 10): E=excellent, F=fair, F—=poor to fair, F+=a grade better than fair, F+— 
variable quality (some poor to fair, some fair to good); G=good, G—=a grade poorer than good, G+= 
a grade Bere than good, G4+=vVariable quality (some fair to good, some good to excellent), P=poor, Vp= 
very poor. 
Group 1—AWNED, GLUMES GLABROUS, KERNEL SEMIHARD TO HARD.
