All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
The purpose of this paper is to set forth the purpose of wheat hybridization. To do this properly it is necessary to know the history of hybridization of plants. Also to know some of the workers in this field and the hybrids produced by them. In the work at the Experiment Stations the various experimenters have discovered many interesting facts which it is necessary to know and understand. To thoroughly comprehend the work it is also necessary to do the actual processes of the work and to carry the hybrid through several generations and eventually to the goal for which …

It was felt that an experiment carried out with the above questions in view would bring out many facts upon which to base conclusions in answering the questions of the Sugar Company.
