Barley (Hordeum sp.) is a principal cereal crop throughout much of the world and is of great economic importance in the United States. Spring barley is a leading cereal crop in Utah. Barley has many desirable characteristics which make it an excellent plant for genetic studies. Some of these characteristics are low chromosome number, almost complete self-fertilization, relative ease of hybridization, and easily classified hereditary characters. The establishment of genes or factors at definite loci in linkage groups is a valuable aid in furthering breeding programs and the ultimate improvement of barley. All seven linkage groups have been established although the location of only a small number of genes is known in some of them and most of these genes were mapped from information obtained from crosses involving only two or three factor pairs. Theis thesis deals with determining the location of five genes belived to be in linkage group IV and to establish new linkages if possible. specifically planned crosses involving from tow to five of these genes were used in this study.
