Associated Characters. 



(1) Earliness, other things being equal, usually tends to high per- 

 centage of ear to stover and conversely, although this ratio is more or 

 less modified by season, soil, fertilization, breeding, and selection. 

 (2) Varieties producing two ears »per stalk are generally more pro- 

 ductive of shelled corn per acre than those bearing only one ear per 

 stalk, although it may be a large one. (3) Medium maturing varie- 

 ties, in our experiments, have been the ones, generally, to give the 

 largest yields per acre of shelled corn. (4) Small kernels usually 

 possess low vitality and those kernels with small germs contain a 

 small percentage of fat or oil and reduced feeding value, especially 

 for fattening animals. (5) Varieties with good root and leaf devel- 

 opment are usually the most resistant ones to drought, and insect and 

 disease ravages.
