Themost important are characters relating to: a. Maturity and Soundness of grains, which is indicat-ed by the fullness of the grains and by being tight on thecob when dry. So indness not only means freedom fromdamage, but good germinating quahties. (See germina-tion tests). b. Density of Ear is indicated by weight or heavinessin proportion to size. Well matured, closely fitting grains, Cam 325 well filled butts and tips, and a high per cent of grain tototal weight of ear, are characters that indicate density.(See Fig. 204). c.

Selecting the Better Producing Strains requiresmore time and more care than selecting for stalk and earcharacters. Seed from an ear having extra good physicalquahties will not necessarily be a superior fielder, thoughin a general way it will be some better than seed from anear having poor physical quality.
