Inheritance Studies And Possible Linkage Relationships In Barley Involving Five Factor Pairs, Freeman J. Byington

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Many studies on inheritance in barley have been made, but very little progress has as yet been obtained. Barley in many ways is an attractive plant with which to make inheritance studies. Unlike common wheat with 21 chromosome pairs and few distinct characters, barley has only 7 chromosome pairs and consequently only 7 possible linkage groups and many distinct characters that may be readily recognized. The chief difficulty is that many of these characters cannot be readily classified because a number of factors may be responsible for their production.

The purpose of this project has been to study in considerable …

Bulk Hybridization Of Smooth Bromegrass (Bromus Inermis), Wayne E. Domingo

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Large populations of controlled hybrids are essential to the most rapid progress in many phases of plant breeding programs. Plant species vary in the ease with which they may be hybridized. Hand hybridization of forage grasses is usually slow and laborious, and the minuteness of the floral parts of most of the species which have perfect flowers renders their hybridization by hand especially difficult and tedious. This difficulty limits the use that forage grass breeders are making of the significant principles of hybridization and thereby retards progress in this phase of plant breeding. Any dependable, rapid technique of hybridization which …

Relationship Between Size Of Farm Business And Labor Income On Utah Farms, Milton S. Folkman

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Since the turn of the century there has been a trend within the State of Utah toward more and smaller farms. The original farm units taken up by the early settlers of this state have been divided and subdivided until Utah today has hundreds of uneconomical-sized farms too small to be operated profitably under their present organization.
