Corn SelJ-Pollenated and Crossed With Teosinte 



The upper ear is an ordinary ear of corn, presenting 

 no marked peculiarities. Thz lower ear was developed by 

 pollemzing the corn silk with pollen from the primitive type of corn 

 called teosinte, which is illustrated on earlier pages of the present 

 volume. The influence of the pollen-parent is clearly 

 shown in the modified form of the kernels. With ' 

 most plants the pollen does not directly 

 effect the fruit, but corn is an excep- 

 tion in this regard.
