Some Methods of Recording Data in Timothy Breeding 1

Certain methods of obtaining records, which have been used during the past few years in connection with timothy breeding experiments, are described in this paper to illustrate the advantage of substituting quantitative data for those which are merely the results of general observations. For several years past the writer has been engaged in timothy breeding investigations, at the Timothy Breeding Station, which is conducted cooperatively by the United States Department of Agriculture and the Ohio Agricultural Experiment Station, at Elyria, Ohio. The breeding of timothy is a phase of experimental agronomy which is of very recent development. Many of the methods which are used in timothy breeding, consequently, have to be originated as the work progresses.
