Available in PDF, EPUB and Kindle. Book excerpt: 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. This thesis deals with determining the location of five genes believed to be in linkage group IV and to establish new linkages if possible. Specifically planned crosses involving from two to five of these genes were used in this study.

Book excerpt: This book presents an overview of the state-of-the-art in barley genome analysis, covering all aspects of sequencing the genome and translating this important information into new knowledge in basic and applied crop plant biology and new tools for research and crop improvement. Unlimited access to a high-quality reference sequence is removing one of the major constraints in basic and applied research. This book summarizes the advanced knowledge of the composition of the barley genome, its genes and the much larger non-coding part of the genome, and how this information facilitates studying the specific characteristics of barley. One of the oldest domesticated crops, barley is the small grain cereal species that is best adapted to the highest altitudes and latitudes, and it exhibits the greatest tolerance to most abiotic stresses. With comprehensive access to the genome sequence, barley’s importance as a genetic model in comparative studies on crop species like wheat, rye, oats and even rice is likely to increase.

Book Synopsis Inheritance of Certain Characters and the Linkage Relationships of Factors on Chromosome IV in Barley by : Claude Junius Jenkins
Download or read book Inheritance of Certain Characters and the Linkage Relationships of Factors on Chromosome IV in Barley written by Claude Junius Jenkins and published by . This book was released on 1950 with total page 82 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plant breeding and the development of new or better varieties of plants are essential parts of modern agronomy, horticulture and forestry. The basis for such improvement is knowledge of the factors and principles of genetics. A number of genetic studies have been made with barley in recent years. This is partly because of the commercial importance of the crop, and partly because of the many distinct heritable characters of barley plants. The cultivated species of barley offers the plant breeder and geneticist a wealth of material for genetic studies. Varieties differ in a great many readily distinguishable characters, species hybridize readily, and their small number of chromosomes make it good material for inheritance studies. The barley genetic work has been divided among the principal workers in the U.S., each being responsible for one linkage group. This station has been assigned group IV of which this study is a part. A study of the inheritance of other genes not located in linkage group IV, but appearing in the crosses used, has also been made. This investigation is a by-product of the cereal breeding and improvement program being carried on at the Utah Agricultural Experiment Station.

Book Synopsis Linkage and Inheritance Studies in Barley (Hordeum) by : Robert E. Heiner
Download or read book Linkage and Inheritance Studies in Barley (Hordeum) written by Robert E. Heiner and published by . This book was released on 1958 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 that linkage group III and VII should be combined in separate arms of the same chromosome. The present work is a study of character inheritance and linkage relationships aimed toward identifying the number of genes conditioning individual characters and associating them with linkage groups. When barley genes are more completely placed in their respective linkage groups, breeding for various good characteristics can be enhanced materially. This is readily accomplished when linkages are found between desirable characters for which selection is difficult or time-consuming.
Book Synopsis A Genetic Study of Linkage and Inheritance in Barley by : Jerald Dean Oldham
Download or read book A Genetic Study of Linkage and Inheritance in Barley written by Jerald Dean Oldham and published by . This book was released on 1962 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: Barley is excellent material for use in genetic studies. It is adapted to many environments and has a large number of contrasting characters. Large populations can be grown on a small area of land in one season. It is a diploid with seven chromosome pairs. Each of these seven chromosome pairs can be identified cytologically. There are seven linkage groups corresponding to the seven chromosome pairs. Previously a Roman numeral was assigned for each linkage group. However, in 1954, Kramer, Veyl, and Hanson conducted an experiment involving translocation stocks which suggested linkage groups III and VII were actually located on the same chromosome. Since that time a new system using Arabic numeral s to designate linkage was adopted by the Fourth Annual Barley Research Worker's Confer ence. This latter system will be followed throughout this study.

Book Synopsis Diversity in Barley (Hordeum vulgare) by : R. von Bothmer
Download or read book Diversity in Barley (Hordeum vulgare) written by R. von Bothmer and published by Elsevier. This book was released on 2003-07-03 with total page 307 pages. Available in PDF, EPUB and Kindle. Book excerpt: Genetic diversity is one of the main resources sustaining human life. Food security largely depends on the availability and utilization of this diversity, which is of strategic importance for countries and companies. Conservation and utilization of biodiversity is thus currently an urgent area of global debate and concern. Barley is a major crop in the world used for food, feed and malt, and with a wide religious and ethnic importance. The crop was domesticated in Neolithic time in SW Asia and spread rapidly under cultivation to new areas. Nowadays it is one of the most widespread and widely adapted crops grown under contrasting edaphic conditions. Adaptations to new environments, different agricultural practices and selection for different uses have further added to the complex diversity pattern. Is it at all possible to give a complete picture of the diversity in a crop or wild species? Are we, by adding new technologies, only revealing parts of the diversity? Do different sets of data show similar or conflicting pictures of genetic diversity? Will the large genome size reduce the role of barley as a model organism in these current sequencing days? Or, are there still major reasons to continue to work with this beautiful crop? The aim of this book is to cover the complex issue of diversification in time and space in a single crop: barley. Leading scientists from various fields describe the entire variation pattern in different sets of characters and an attempt is made for a synthesis to a holistic picture. The book proposes ways to use the achievements of diversity studies in future research and breeding programmes.

Book Synopsis The Rye Genome by : M. Timothy Rabanus-Wallace
Download or read book The Rye Genome written by M. Timothy Rabanus-Wallace and published by Springer Nature. This book was released on 2021-10-25 with total page 251 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book celebrates the dawn of the rye genomics era with concise, comprehensive, and accessible reviews on the current state of rye genomic research, written by experts in the field for students, researchers and growers. To most, rye is the key ingredient in a flavoursome bread or their favourite American whisky. To a farmer, rye is the remarkable grain that tolerates the harshest winters and the most unforgiving soils, befitting its legacy as the life-giving seed that fed the ancient civilisations of northern Eurasia. Since the mid-1900s, scientists have employed genetic approaches to better understand and utilize rye, but only since the technological advances of the mid-2010s has the possibility of addressing questions using rye genome assemblies become a reality. Alongside the secret of its unique survival abilities, rye genomics has accelerated research on a host of intriguing topics such as the complex history of rye’s domestication by humans, the nature of genes that switch fertility on and off, the function and origin of accessory chromosomes, and the evolution of selfish DNA.

Book Synopsis Doubled Haploid Production in Crop Plants by : M. Maluszynski
Download or read book Doubled Haploid Production in Crop Plants written by M. Maluszynski and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 451 pages. Available in PDF, EPUB and Kindle. Book excerpt: The production of doubled haploids has become a necessary tool in advanced plant breeding institutes and commercial companies for breeding many crop species. However, the development of new, more efficient and cheaper large scale production protocols has meant that doubled haploids are also recently being applied in less advanced breeding programmes. This Manual was prepared to stimulate the wider use of this technology for speeding and opening up new breeding possibilities for many crops including some woody tree species. Since the construction of genetic maps using molecular markers requires the development of segregating doubled haploid populations in numerous crop species, we hope that this Manual will also help molecular biologists in establishing such mapping populations. For many years, both the Food and Agriculture Organization of the United Nations (FAO) and the International Atomic Energy Agency (IAEA) have supported and coordinated research that focuses on development of more efficient doubled haploid production methods and their applications in breeding of new varieties and basic research through their Plant Breeding and Genetics Section of the Joint F AO/IAEA Division of Nuclear Techniques in Food and Agriculture. The first F AO/IAEA scientific network (Coordinated Research Programme - CRP) dealing with doubled haploids was initiated by the Plant Breeding and Genetics Section in 1986.
