Excerpt from The Analysis of Characters in Corn and Their Behavior in Transmission

The work, of which this paper is a partial report, has in reality been a search for characters in the corn plant; how many and what are they; how do they behave in transmission? In the general plan of the investigation, it was decided to begin with the germinating seed and continue through the life history of the plant, going as far 'as time and facilities would permit.* The plan followed was to study characters wherever they might be found, rather than to make a group study of varieties or strains as a whole. The topics used as headings in the report of the investigation are not necessarily characters Of last analysis, but may represent more or less complex bundles of genetic units.

To a very large extent. Investigators in hybridization, before Mendel's law was applied, saw their material in generalities. Mendel's far - sightedness in com paring individual characters only and not plants as a whole, together with his careful watch upon the behavior of these individual characters through several generations of the progeny, enabled him to secure the facts which led to the discovery of this great law, overwhelming in its importance, which bears his name. Following its rediscovery in 1900, methods in the study of heredity have been revolutionized. Thus the era of mass selection in corn breeding is also rapidly passing and the practice is to be superseded bv more rational methods.

Some general principles of heredity, which have a direct bearing on the subject in hand, will be considered briefly before entering into the discussion of the characters themselves.
