- ... The modern method of corn breeding has resulted from the development of a sensible genetic interpretation of the results of selfing and crossing in naturally cross-pollinated species and in these studies the work with corn has played an important role. Perhaps, of equal importance is the fact that adapted varieties cannot, as a rule, be further improved by the use of earlier methods. To the agrono ...

- ... The results of these experiments show that the absorption abilities of selfed lines and of crosses between them vary widely with respect to certain of the essential mineral nutrients and to the iron and aluminum salts in the soil solution. The quantities of certain of the ash constituents absorbed by the hybrids are intermediate between the amounts absorbed by the parent lines. Less iron and alumi ...
