Book excerpt: Ein besseres Verständnis der genetischen Diversität und ihrer Verteilung ist nicht nur für eine effektive Nutzung der genetischen Ressourcen in Züchtungsprogrammen notwendig, sondern auch für die Gestaltung von Sammelreisen und Erhaltungsprojekten. Dazu wurde die Diversität bei äthiopischen tetraploiden Weizenlandsorten mittels morphologischer und molekularer Marker untersucht. Für die morphologische Analyse wurden 271 Akzessionen auf 13 morphologische und agronomische Merkmale untersucht. Zur Anwendung kamen statistische Verfahren wie der Shannon Weaver Diversitäts-Index und multivariate Techniken (Clustering, Ordination, Diskriminanz-Analyse). Die Ergebnisse der Hauptkomponenten – Analyse ergaben, dass die ersten fünf Hauptkomponenten mit Eigenvalues >175, 42% der Gesamtvariation aller Akzessionen bestimmen. Sowohl die Cluster-Analyse als auch Scatter-Plot von PC1 gegenüber PC2 zeigten das Fehlen eines klaren Musters einer regionalen Gruppenierung, da die Akzessionen verschiedener Gebiete über viele Cluster verteilt waren. Mit der Diskriminanz-Analyse konnten die Akzessionen mit einer mittelren korrekten Klassifikationsrate von 60,9% differenziert werden. Wichtige Variablen der Diskriminanz-Analyse waren Tage bis zum Ährenschieben und Ährenlänge. Der Shannon-Weaver Diversitäts-Index für alle Merkmale betrug 0,74. Die Aufteilung der phänotypischen Gesamt-Diversität in eine Diversität zwischen den und in eine solche innerhalb der Regionen ergab Werte von 0,71 bzw. 0,29. Im allgemeinen zeigte die phänotypsche Diversität beträchtliche Unterschiede für jedes Merkmal in verschiedenen geographischen Regionen und Höhenklassen.

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.

Download or read book Genes in the Field written by International Plant Genetic Resources Institute and published by IDRC. This book was released on 2000 with total page 301 pages. Available in PDF, EPUB and Kindle. Book excerpt: Genes in the Field provides an interdisciplinary foundation for an important new conservation program: maintaining biological resources of crop plants within the systems where they have evolved. The book offers a truly global vision of the on-farm conservation movement and, like no other before it, provides a comprehensive review of the issues and challenges of on-farm conservation of genetic resources. The book's chapters are written by a collection of outstanding scholars and academics from a variety of disciplines; they include biologists, agronomists, anthropologists, economists, lawyers and agricultural development specialists. Genes in the Field is truly global in scope and multidisciplinary in character. It will appeal to a large, varied and international audience. Its most general appeal will be to professionals in the fields of conservation and agricultural development, particularly those who are involved in planning or implementing conservation programs. For course work, the book will be appropriate for graduate programs in agricultural development and conservation.
Download or read book Rediscovery of Landraces as a Resource for the Future written by Oscar Grillo and published by BoD – Books on Demand. This book was released on 2018-09-12 with total page 206 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent years, all over the world, the attention paid to local and traditional productions is growing, especially in the agro-food sector. Maybe, it is not only due to the impact of globalization and the social and economic changes but also due to the increased consideration to health and nutritional aspects of food. Hence, for economic, social, historical, and nutritional reasons, this trend has led to the rediscovery and reuse of landraces of many different crops, responding to requests for more and more demanding market. This volume collects examples of local crops and old landraces of different areas of the planet that testify the extreme importance of the relation existing among a land, the local productions, the historical traditions, the conservation of biodiversity, the health benefits, the environmental impact and the local economies, also including the significance to dedicate resources to scientific researches in local crops.
Download or read book The Barley Genome written by Nils Stein and published by Springer. This book was released on 2018-08-18 with total page 400 pages. Available in PDF, EPUB and Kindle. 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.

Download or read book Plant Genetic Resources of Ethiopia written by Jan Engels and published by Cambridge University Press. This book was released on 1991-03-21 with total page 404 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the world centers of crop evolution and origin, Ethiopia has long been recognized as an important area of diversity for several major and various minor crops. Based on an international conference held in Addis Ababa, this book describes how plant genetic diversity in Ethiopia is of vital importance in breeding new varieties of crops with desirable characteristics, such as increased resistance to pests and diseases and greater adaptation to heat and drought. The three main sections in the book consider the Ethiopian center of diversity, germ plasm or genetic material collection and conservation in Ethiopia, and the evaluation and utilization of Ethiopian genetic resources. A broad range of food and feed crops and plants of medicinal and industrial importance are discussed, both at a national and international level. A brief account of conservation strategies and gene bank problems unique to Ethiopia is also given. The importance of Ethiopia's plant genetic resources to world agriculture has been demonstrated on more than one occasion. Plant breeders, geneticists, and botanists throughout the world will, therefore, find this unique book a valuable source of information and an essential reference work.
