grown in the sections in which they are superior. It is also important 

 that the methods of selection, and care of seed employed by Michigan's 

 best corn growers in the development of these varieties be more widely 

 employed. 



By observing the yieldiug ability in the field of improved varieties 

 for a number of years and assembling these varieties and numerous 

 others of promise in carefully conducted variety tests throughout the 

 State and at the Michigan Experiment Station, it has been made pos- 

 sible to designate, according to sectional adaptation, the leading corn 

 varieties, which may be taken as dependable standards. Without doubt 

 future experiments with corn varieties may develop even better strains 

 and establish new varieties, which may replace many of the present ones, 

 but it is certain that the varieties here designated have proven their 

 adaptation and yielding ability, and are much superior to the majority 

 of ordinary varieties usually grown. 



APPROXIMATE SECTIONAL ADAPTATION OF LEADING 

 MICHIGAN COKN VAKIETIES 



Section 1 — f^outlicm Micliigan: 



The Duncan Yellow Dent, Early Reed's Yellow Dent, Early Leaming, 

 Murdock, Early Silver King, Folks White Cap, Golden Glow, Lawrence 

 Yellow Dent, and Pickett Yellow Dent. 



For silage these varieties and varieties from northern Ohio, northern 

 Indiana, northern Iowa, and northern Illinois which are early enough 

 to reach the dented and glazed kernel stage of maturity. 



Section 2 — Central Micliigan: 



Pickett Golden Glow, Geddes Early Silver King and Folks White Cap. 

 For silage, these varieties, and varieties from Section 1. 



Section S— Northern MicJihjaii: 



Early Golden Glow, Wisconsin 12 and No. 25, Early Pickett, North- 

 western Dent, Ogemaw White Cap and Flint varieties. 



For silage — these varieties, and varieties from central Mchigan. 



Section // — 



No safe grain maturing varieties. The varieties of Section 3, are 

 recommended for silage under conditions where silage can be produced. 



The accompanying map shows graphically the approximate adapta- 

 tion of varieties listed. It must be kept in mind that definite boundaries 

 cannot be established, and that exceptionally cold and late soils in 

 southern localities require early strains such as are characteristic of 

 more northern sections, while favorably located, quick growing corn 

 soils in northern sections, particularly near Lake Michigan, can produce 

 later strains than the average soil of the region.
