After Bulletin 87, Univer- sity of Illinois Agricultural Experiment Station 385. Qualities sought by the corn breeder. ^ Of the many qualities that may be sought by the corn grower it will be enough here to mention only four of the most important: (1) productiveness; (2) high percentage of proteins; (3) high percentage of oil; (4) low percentage of oil. With reference to (1) it suffices here to say that the average yield of corn for the entire United States, according to statistics for 1908, was a little over 26 bushels per acre; for the New England States, with no better soil and a poorer climate, it was bushels; and for some New England growers it was 100 or more bushels per acre. No small part of the difference between the average 26-bushel yield and the 100- bushel yield depends on the choice of seed.^ Greatly increased care in its selection would probably at once add.
