Prospects For Gene Lntrogression From Hordeum Bulbosum L. Into Barley (H. Vulgare L.)., R. A. Pickering, A. M. Hill, G. M. Timmerman-Vaughan, E. M. Forbes, M. G. Cromey, M. J. Gilpin, M. Michel, M. Scholz
Herbarium Publications
Hybridizations between Hordeum vulgare L. (cultivated barley) and H. bulbosum L. have been performed over many years with two aims. First, the production of doubled haploid barley cultivars (Kasha and Kao 1970); second, the transfer of desirable traits such as resistance to fungal and viral pathogens from the wild species into barley. Apart from the report of an occasional recombinant (Xu and Kasha 1992; Pickering et al 1994), successful gene introgression has been hampered by several barriers. In this report we will describe recent progress in overcoming these barriers.

An Inheritance And Linkage Study Of 19 Factor Pairs In Barley, Francis Cheney Lebaron
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Barley, during the past three decades, has been used considerably for the study of linkage groups and character inheritance. The commercial varieties are diploids, having seven pairs of chromosomes. Six linkage groups have been established. According to studies on interchange by Kramer et al. (1954), two linkage groups, formerly designated as III and VII, may be separate arms of the same chromosome. They are now generally considered as one linkage group.
Though more than two hundred characters have been investigated, less than sixty have been assigned relative positions on genetic maps. In many cases, selection for good characters is …

Linkage And Inheritance Studies In Barley (Hordeum), Robert E. Heiner
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Barley has had wide acceptance not only as a cultivated crop but also as an excellent source of genetic material. Barley was being used in inheritance studies by Tschermak when he rediscovered Mendel's laws of heredity. Since then barley has become one of the most widely used plants for genetic studies known today.
More than 100 characters have been investigated indicating the relative ease of classification. There are 7 linkage groups corresponding to the 7 chromosomes in which 2 or more characters have been located as reported by Robertson (1939). But Kramer, Veyl, and Hanson (1954), from translocation experiments, suggest …

Bulletin No. 361 - How Much Barley For Turkeys, C. I. Draper
UAES Bulletins
During recent years high energy turkey diets containing com as the sole source of ground grain have been fed extensively. Corn has been used as the grain part of the mash because of its high energy, low fiber qualities, and because its deficiencies in amino acids, vitamins, and minerals have been determined by research. Supplements to overcome these deficiencies have been added to high energy corn diets. Excellent results have been obtained when adequate supplementation of vitamins, amino acids, and minerals were made.
In this area frequent inquiries are made as to the possibilities of substituting barley for part or …

A Study Of Semisterility And Its Lineage Relationships In Translocation Stocks Of Barley, Horace Marr Waddoups
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Barley (Hordrium sp.) is the most important spring sown cereal crop in Utah, both in acreage and in yield of total digestible nutrients per unit area. It also rates high as a feed crop in the United States. For this reason it is important that varieties are available which are high in yield, high in quality, and disease resistant, along with other desirable characteristics. In order to work toward this end most efficiently, it is first necessary that the genetics of the barley plant be worked out.

Bulletin No. 178 - The Irrigation Of Barley, F. S. Harris, D. W. Pittman
UAES Bulletins
The proper use of irrigation water is one of the most important problems of every comnunity and of every farmer in an irrigated district. The irrigation farmer has largely under his control one of the most important factors in determining the yield and quality of his crops and one over which all other farmers have little control at all. On the other hand, in an arid district there is generally less available irrigation water than is needed to give the optimum amount to all the land, or if one region receives an excess there is generally an accumulation of alkali …

The testing of varieties is by no means the most important work of the Station. It, however, has its value in bringing into the State [Utah], and acclimating, new varieties that may be suited to our conditions better than any now grown. The results reached in these tests ought to receive the careful attention of our farmers, because success in raising cereals depends upon securing the varieties best suited to our purpose, and in growing those in greatest demand.
The experiments recorded in the following pages give the results of variety tests with wheat, oats and barley, and, in addition, …
