Love, Collaborators, Office of Cereal Investigations (in cooperation with the Iowa and Cornell University Agricultural Experiment Stations).2 INTRODUCTION. The breeding of oats was begun by the Bureau of Plant Industry in 1902. In that year Mr. Jesse B. Norton, then of the Plant-Breeding Laboratory, grew a collection of varieties at the Arlington Experi- mental Farm, near Washington, D. C, and made a large number of crosses. The resulting seed was planted in the spring of 1903 at Willey, 111. The following year the work was transferred to the vicinity of Bloomington, 111., where it was conducted from 1904 to Field-plat tests of a number of commercial varieties were also made at Willey in 1903 and during the earlier years of the work near Bloomington. The experiments were confined to nursery tests in 1907 and 1908. Pure-line selections were made from these plats of commercial varieties, and material for crossing was also taken from them. The first selections were made from the hybrids in 1904, and reselections were made from time to time as further breaking up was apparent. All these selections were first grown in head rows, and those which appeared to be most desirable were grown in suc- ceeding years in nursery rows of uniform length for comparative tests. In 1907 considerable numbers of the selections were sent to the Kentucky, Iowa, and Cornell University (New York) agricultural 1 This bulletin is intended for the use of farmers, agronomists, and cereal breeders, to whom the com- parative data on selections from hybrids and commercial varieties should be of interest.
