Advances in Wheat Genetics: From Genome to Field
Author: Yasunari OgiharaPublisher: Springer
ISBN: 4431556753
Category : Science
Languages : en
Pages : 421
Book Description
This proceedings is a collection of 46 selected papers that were presented at the 12th International Wheat Genetics Symposium (IWGS). Since the launch of the wheat genome sequencing project in 2005, the arrival of draft genome sequences has marked a new era in wheat genetics and genomics, catalyzing rapid advancement in the field. This book provides a comprehensive review of the forefront of wheat research, across various important topics such as germplasm and genetic diversity, cytogenetics and allopolyploid evolution, genome sequencing, structural and functional genomics, gene function and molecular biology, biotic stress, abiotic stress, grain quality, and classical and molecular breeding. Following an introduction, 9 parts of the book are dedicated to each of these topics. A final, 11th part entitled “Toward Sustainable Wheat Production” contains 7 excellent papers that were presented in the 12th IWGS Special Session supported by the OECD. With rapid population growth and radical climate changes, the world faces a global food crisis and is in need of another Green Revolution to boost yields of wheat and other widely grown staple crops. Although this book focuses on wheat, many of the newly developed techniques and results presented here can be applied to other plant species with large and complex genomes. As such, this volume is highly recommended for all students and researchers in wheat sciences and related plant sciences and for those who are interested in stable food production and food security.
Economic Analysis of Diversity in Modern Wheat

Languages : en
Pages : 207
Book Description
Scientific breeding in the twentieth century greatly accelerated wheat`s evolution, producing high-yielding varieties that helped avoid famine in many developing countries. Emerging scientific tools hold promise for identifying and tapping new, useful genetic diversity within wheat`s primary and secondary gene pools and, through genetic engineering, beyond.The book describes generally how policies affect wheat genetic diversity; it looks at historical changes in wheat genetic diversity, as policy and priorities have evolved; it identifies factors that explain changes and differences in spatial diversity; and finally, it analyzes the productivity impacts of changes in diversity. Chapters define various types of crop genetic diversity and ways to measure them, framing the definitions and metrics in the contexts for which they are most relevant.
Wheat Landraces

Pages : 268
Book Description
Landraces possess a very large genetic base in population structure and are dynamic populations of cultivated plants with historical origin, distinct identity, and without any formal crop improvement. They are often genetically diverse, locally adapted, and associated with traditional farming systems. Resistance genes to biotic and abiotic stress factors, which are especially diversified in landraces, are of great interest to plant breeders, faced with global climate challenge. In addition, gene pools made of different landraces grown in different ecological conditions can be used for wheat breeding to enhance quality; yield and other desirable agricultural parameters. An estimated 75% of the genetic diversity of crop plants was lost in the last century due to the replacement of high yielding modern varieties. There is, thus, an urgent need to preserve existing species, not only for posterity but also as a means to secure food supply for a rising world population. In this book, we provide an overview of wheat landraces with special attention to genetic diversities, conservation, and utilization.

Pages : 292
Book Description
Addressing concerns about the loss of valuable genetic resources and crop vulnerability arising from widespread cultivation of genetically uniform varieties, this volume assembles a group of studies focusing on the fundamental economic issues related to genetic diversity in crop species, with reference to experiences in a number of developing countries. Topics include the valuation of crop genetic resources conserved ex situ; conserving crop diversity on farms; the impacts of crop diversity on productivity and stability; and policies and genetic resource utilization.

Book Description
This is a reference book which describes importance, use and basic information relevant to Wheat and its improvement. In reference to genetic diversity analysis, data was collected for yield and its components and utilized for genetic evaluation of diverse wheat genotypes. The analysis revealed high significant genetic variation for most of the yield components. Recent research findings in wheat improvement aspects have been incorporated in the book. The present research would be fruitful during formulating breeding strategies for wheat improvement. Methodology, experimental findings and their relation with earlier researches has been elaborated in the book. Thousand grain weight, plot yield, grains per spike, tiller per meter and ear length are found key traits for genetic evaluation of wheat genotypes and should be utilized in wheat breeding programmes. Genetic diversity analysis using Cluster and principal component analysis has explored an opportunity to identify diversified genotypes for crop improvement.Present book is basically written for Plant Breeding Scholar and persons interested in Wheat research.
