We take no seed from a row which produces a large proportion of 

 imperfect plants, barren stalks, small ears or a low yield, even though a 

 few apparently good seed ears might be found in the crop which that 

 row yields. 



The points to be considered in the selection of the field rows, and 

 finally in the individual plants from which seed ears may be taken should 

 include the per cent of " stand " of plants, the height and physical propor- 

 tions of the plant, the character and amount of foliage, the position of 

 the ear on the stalk, the length and size of the ear shank, the per cant 

 of ear-bearing plants, the time of maturity, the total yield of the row, the 

 average weight of the ears, and the number of good seed ears which the 

 row produces.
