History.âHybrid 128 was originated at Washington Agricultural Experi- ment Station, Pullman, Wash. Its history has been recorded by Schafer and Gaines (170, p. 8) as follows: Hybrid No. 128 is a cross between Jones Winter Fife and Little Club. It was originated in 1899 by Prof. W. J. Spillman. After being selected and tested for eight years it was distributed to ranchers for further testing. Prof. Spillman started his work in wheat breeding at the Washington Agri- cultural Experiment Station in 1899. Valuable results were obtained, Hybrid 128 being only one of the varieties which resulted from the first crosses. The work was hardly commenced, however, before he left the institution, and the important task of making the selections, testing the many strains, and dis- tributing the new varieties was left to other workers. His work with wheat, however, resulted in some of the very earliest discoveries of the fundamental principles of heredity in plant breeding. He left Pullman in June. 1902, and it was not until 1909 that he published the re- sults of his studies in hybridization (182). In the same year he published a more popular bulletin from the Wash- Fig. 69.âOutline map . . ,A , ^ . r, . ,., of a portion of the ihgton Agricultural Experiment Station, which gave some Pacific Northwest, of the results of his early experiments (183). showing the distri- The wheat breeding was continued at Pullman by bution of Hybrid Mess
