The data presented in this thesis are the results obtained from a study of the F2 and F3 generations from a cross between the wheat varieties, Dicklow and Hard Federation. Toward the end of the summer of 1922 this problem was assigned to me by Professor George Stewart. The plants then growing in the field were in the F2 generation, the cross having been made in 1920 by Professor Stewart. The chief purpose of the cross was to improve the grain quality of spring-irrigated wheat by the application of Mendelian principles in such a way as to …

Two methods of crop improvement are open to the plant breeder. Pure-line selection, which might be mentioned first, deals with the natural variability in plant populations. Thru selection, isolation, and comparative yield tests superior individuals are located. Nothing, however, can be added which the plant does not already have. Here hybridization provides a new starting point. Increased variation, new combination of characters, and thus greater opportunities are provided for improvement. The present investigation has for its purpose a study of the latter phase of this subject.

The results presented in this paper are from data accumulated by a study of the F3 generation of a cross between the two varieties, Sevier and New Zealand wheat. This cross was made during the summer of 1920 by Professor George Stewart with the object of combining the high-yielding power of Sevier with the strong straw of New Zealand. In the fall of 1922 the problem was assigned to me, at which time I selected about 150 superior plants, possessing the desired characteristics, at least so far as appearance was concerned. Since then these plants and the F3 generation have …
