RESULTS WITH INDIAN WHEATS 
Seed of a number of selections of Indian wheats was smutted with 
spores of TiUetia tritici and sown at Moro, Oreg., from March 28 to 
April 9, 1919. Most of these selections became heavily infected in 
these trials, and none were free enough from bunt to indicate any 
marked degree of resistance. One selection, C. I. No. 4909, had 
only 12 per cent of infection. The remainder of these selections 
showed 34 per cent or more of bunt and are grouped in the following 
list by their Cereal Investigations (C. I.) numbers according to per- 
centages of infection.

5461, 5462, 5466, 5468, 5470, 5471 
The results show that these wheats are highly susceptible to bunt 
and that it will not be an easy matter to find resistant strains among 
them. As they are not grown commercially in the United States, it 
will not be desirable to give them further consideration here.
