Linkage Relationships Of Located And Unlocated Genetic Testers In Certain Normal And Translocation Stocks Of Barley, William Ralph Andersen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Barley is an economically important cereal crop throughout most of the world. The study and elucidation of the genetic complex of this plant will add to its extensive usefulness to man, and will also provide valuable information for similar research projects on other crop plants.

Linkage Relationships In Group Iv In Barley, George W. Wheatley

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The development of new and better varieties of plants through plant breeding is essential to meet certain needs of a changing world. Genetics and a knowledge of its principles are the basis for such improvement.

Barley has been used rather extensively in linkage relations studies. Its desirable characteristics are: (1) interspecific fertility and relative ease of hybridization, (2) numerous characters that are easily differentiated, (3) its commercial importance as a crop and (4) there are seven chromosome pairs in each of the four cultivated species.

More than one hundred characters in barley have been investigated. Seven linkage groups in which …

Inheritance Of 16 Barley Characters And Their Linkage Relationships, Tejpal Singh Gill

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The assignment of genetic factors to definite loci in the hereditary mechanism has been a great step in the progress of biology. Of the cereal crops, barley (Hordeum sp.), a crop of economic importance, offers a superior opportunity for genetic studies. Its adaptation to wide varieties of conditions, with a wealth of easily differentiated characters and only seven pairs of chromosomes, the barley plant provides excellent material for linkage studies.

Although there is a vast amount of literature dealing with inheritance in barley, yet knowledge of the subject is still very limited. The mode of inheritance of about one hundred …

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.
