This book was released on 2006-01-19 with total page 200 pages. Available in PDF, EPUB and Kindle. 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.

Book excerpt: Developments in Plant Genetics and Breeding, 1A: Isozymes in Plant Genetics and Breeding, Part A focuses on the advancements in the processes, methodologies, and approaches involved in the study of isozymes, including its role in plant genetics and breeding. The selection first elaborates on the historical perspectives of plant isozymes, plant genetics, and isozyme systems to study gene regulation during development. Discussions focus on the use of isozyme and similar comparisons to study differential gene regulation, gene preservation, dissemination of cultivars, propagation of cultivars and breeding lines, and studies on the effect of viral infection and hormones on isozyme expression. The text then examines allozymes in gene dosage studies, gene mapping, and plastid isozymes. The manuscript takes a look at the genetics of mitochondrial isozymes, evolution of plant isozymes, and detection of somatic variation. Topics include evolution of isozymes in plants, generation of isozymes, glutamate dehydrogenase, glutamate-oxaloacetate transaminase, and malate dehydrogenase. The text also ponders on enzyme activity staining, isozymic variation and plant breeders' rights, genetic purity of commercial seed lots, and use of isozymes in plant disease research. The selection is a valuable reference for researchers interested in the role of isozymes in plant genetics and breeding.

Download or read book Quality Breeding in Field Crops written by Asif M. Iqbal Qureshi and published by Springer. This book was released on 2019-02-15 with total page 284 pages. Available in PDF, EPUB and Kindle. Book excerpt: Development of superior crops that have consistent performance in quality and in quantity has not received the same emphasis in the field of genetics and breeding as merited. Specialty trait requires special focus to propagate. Yet basic germplasm and breeding methodologies optimized to improve crops are often applied in the development of improved specialty types. However, because of the standards required for specialty traits, methods of development and improvement are usually more complex than those for common commodity crops. The same standards of performance are desired, but the genetics of the specialty traits often impose breeding criteria distinct from those of non-specialty possessing crops. Specifically, quality improvement programs have unique characteristics that require careful handling and monitoring during their development for specific needs. Adding value either via alternative products from the large volumes of grain produced or development of specialty types is of interest to producers and processors. This work assimilates the most topical results about quality improvement with contemporary plant breeding approaches.The objective of this book is to provide a summary of the germplasm, methods of development, and specific problems involved for quality breeding. In total, fourteen chapters, written by leading scientists involved in crop improvement research, provide comprehensive coverage of the major factors impacting specialty crop improvement.
Download or read book Alien Gene Transfer in Crop Plants Volume 1 written by Aditya Pratap and published by Springer Science & Business Media. This book was released on 2013-11-01 with total page 323 pages. Available in PDF, EPUB and Kindle. Book excerpt: Genetic engineering and biotechnology along with conventional breeding have played an important role in developing superior cultivars by transferring economically important traits from distant, wild and even unrelated species to the cultivated varieties which otherwise could not have been possible with conventional breeding. There is a vast amount of literature pertaining to the genetic improvement of crops over last few decades. However, the wonderful results achieved by crop scientists in food legumes’ research and development over the years are scattered in different journals of the World. The two volumes in the series ‘Alien Gene Transfer in Crop Plants’ address this issue and offer a comprehensive reference on the developments made in major food crops of the world. These volumes aim at bringing the contributions from globally renowned scientists at one platform in a reader-friendly manner. The 1st volume entitled, ‘Alien Gene Transfer in Crop Plants: Innovations, Methods and Risk Assessment” will deal exclusively with the process and methodology. The contents of this volume have been designed to appraise the readers with all the theoretical and practical aspects of wide hybridization and gene transfer like processes and methods of gene transfer, role of biotechnology with special reference to embryo rescue, genetic transformation, protoplast fusion and molecular marker technology, problems such as cross incompatibility and barriers to distant hybridization and solutions to overcome them. Since wild and weedy relatives of crop plants may have negative traits associated with them, there are always possibilities of linkage drag while transferring alien alleles. Therefore, problems and limitations of alien gene transfer from these species will also be discussed in this series. Further, the associated risks with this and assessment of risks will also be given due weightage.
Download or read book Crop Improvement written by Khalid Rehman Hakeem and published by Springer Science & Business Media. This book was released on 2013-06-13 with total page 504 pages. Available in PDF, EPUB and Kindle. Book excerpt: The improvement of crop species has been a basic pursuit since cultivation began thousands of years ago. To feed an ever increasing world population will require a great increase in food production. Wheat, corn, rice, potato and few others are expected to lead as the most important crops in the world. Enormous efforts are made all over the world to document as well as use these resources. Everybody knows that the introgression of genes in wheat provided the foundation for the “Green Revolution”. Later also demonstrated the great impact that genetic resources have on production. Several factors are contributing to high plant performance under different environmental conditions, therefore an effective and complementary use of all available technological tools and resources is needed to meet the challenge.

Download or read book Genetic and Genomic Resources of Grain Legume Improvement written by Mohar Singh and published by Newnes. This book was released on 2013-07-18 with total page 322 pages. Available in PDF, EPUB and Kindle. Book excerpt: Grain legumes, including common-bean, chickpea, pigeonpea, pea, cowpea, lentil and others, form important constituents of global diets, both vegetarian and non-vegetarian. Despite this significant role, global production has increased only marginally in the past 50 years. The slow production growth, along with a rising human population and improved buying capacity has substantially reduced the per capita availability of food legumes. Changes in environmental climate have also had significant impact on production, creating a need to identify stable donors among genetic resources for environmentally robust genes and designing crops resilient to climate change. Genetic and Genomic Resources of Grain Legume Improvement is the first book to bring together the latest resources in plant genetics and genomics to facilitate the identification of specific germplasm, trait mapping and allele mining to more effectively develop biotic and abiotic-stress-resistant grains. This book will be an invaluable resource for researchers, crop biologists and students working with crop development. - Explores origin, distribution and diversity of grain legumes - Presents information on germplasm collection, evaluation and maintenance - Offers insight into pre-breeding/germplasm enhancement efforts - Integrates genomic and genetic resources in crop improvement - Internationally contributed work
