The same thing here (indicating the next slide). In that plat (indi- 

 cating) there is a yield of about seventy while here (pointing to a plat 

 grown from the Fi seed of two good homozygous strains) is a yield of about 

 one hundred ten bushels. The average in the best open fertilized seed was 

 about seventy-five bushels. 



There (indicating on next slide) is one of those homozygous strains 

 that has proven so superior over a period of four years. On the opposite 

 side may be seen another unusually good one that is entirely unrelated. 

 When these are combined the result is very satisfactory, as may be judged 

 by the plat in the middle practically every grain of corn that was planted 

 produced a stalk with an ear on it like that (indicating). 



A very susceptible strain of corn grown adjacent to a comparatively 



resistant strain. 



This is one of the most gratifying things that has developed in these 

 investigations. When this project is finally completed, as a result of the 

 cooperation that has been so effective heretofore, the improved strains of 

 corn will mean to Illinois farmers exactly what Kanred wheat means to the 

 wheat farmers of Kansas. We fully believe, and I think we are well justi-
