Book Synopsis Advances in Wheat Genetics: From Genome to Field by : Yasunari Ogihara
Download or read book Advances in Wheat Genetics: From Genome to Field written by Yasunari Ogihara and published by Springer. This book was released on 2015-09-15 with total page 421 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Book Synopsis Physiological, Molecular, and Genetic Perspectives of Wheat Improvement by : Shabir H Wani
Download or read book Physiological, Molecular, and Genetic Perspectives of Wheat Improvement written by Shabir H Wani and published by Springer Nature. This book was released on 2020-12-17 with total page 296 pages. Available in PDF, EPUB and Kindle. Book excerpt: World population is growing at an alarming rate and may exceed 9.7 billion by 2050, whereas agricultural productivity has been negatively affected due to yield limiting factors such as biotic and abiotic stresses as a result of global climate change. Wheat is a staple crop for ~20% of the world population and its yield needs be augmented correspondingly in order to satisfy the demands of our increasing world population. “Green revolution”, the introduction of semi-dwarf, high yielding wheat varieties along with improved agronomic management practices, gave rise to a substantial increase in wheat production and self-sufficiency in developing countries that include Mexico, India and other south Asian countries. Since the late 1980’s, however, wheat yield is at a standoff with little fluctuation. The current trend is thus insufficient to meet the demands of an increasing world population. Therefore, while conventional breeding has had a great impact on wheat yield, with climate change becoming a reality, newer molecular breeding and management tools are needed to meet the goal of improving wheat yield for the future. With the advance in our understanding of the wheat genome and more importantly, the role of environmental interactions on productivity, the idea of genomic selection has been proposed to select for multi-genic quantitative traits early in the breeding cycle. Accordingly genomic selection may remodel wheat breeding with gain that is predicted to be 3 to 5 times that of crossbreeding. Phenomics (high-throughput phenotyping) is another fairly recent advancement using contemporary sensors for wheat germplasm screening and as a selection tool. Lastly, CRISPR/Cas9 ribonucleoprotein mediated genome editing technology has been successfully utilized for efficient and specific genome editing of hexaploid bread wheat. In summary, there has been exciting progresses in the development of non-GM wheat plants resistant to biotic and abiotic stress and/or wheat with improved nutritional quality. We believe it is important to highlight these novel research accomplishments for a broader audience, with the hope that our readers will ultimately adopt these powerful technologies for crops improvement in order to meet the demands of an expanding world population.
Download or read book Wheat written by Y. P. S. Bajaj and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 701 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wheat, which is the second most important cereal crop in the world, is being grown in a wide range of climates over an area of about 228 945 thou sand ha with a production of about 535 842 MT in the world. Bread wheat (Triticum aestivum L. ) accounts for 80% of the wheat consumption, howe ver, it is attacked by a large number of pests and pathogens; rusts and smuts cause enormous damage to the crop and reduce the yield drastically in some areas. The major breeding objectives for wheat include grain yield, earliness, resistance to lodging and diseases, spikelet fertility, cold tolerance, leaf duration and net assimilation rate, fertilizer utilization, coleoptile length, nutritional value, organoleptic qualities, and the improvement of charac ters such as color and milling yield. The breeding of wheat by traditional methods has been practiced for centuries, however, it has only now come to a stage where these methods are insufficient to make any further breakthrough or to cope with the world's demand. Although numerous varieties are released every year around the world, they do not last long, and long-term objectives cannot be realized unless more genetic variability is generated. Moreover, the intro duction of exotic genetic stocks and their cultivation over large areas results in the depletion and loss of the native germplasm pool.
Book Synopsis Genetic Improvement in Yield of Wheat by : Edward L. Smith
Download or read book Genetic Improvement in Yield of Wheat written by Edward L. Smith and published by . This book was released on 1986 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many avenues are being explored to further improve wheat yields. Conventional plant breeding will remain the procedure used to incorporate new capabilities into commercial cultivars. Control of diseases through genetic means will remain an important thrust because the old disease organisms mutate to more virulent strains and because new diseases can arise at any time. New biological techniques may allow the introduction of yet unknown genes into breeding stocks. Also, greater understanding of the genetic and physiological makeup of wheat will allow crop and soil scientists to devise ingenious ways to alter the wheat plant to make it an even more important food factory. This special publication, Genetic Improvement in Yield of Wheat, addresses specific research thrusts in wheat improvement. The papers were originally presented as part of a symposium at the Annual Meetings of the American Society of Agronomy-Crop Science Society of America.

Book Synopsis Wheat Landraces by : Nusret Zencirci
Download or read book Wheat Landraces written by Nusret Zencirci and published by Springer Nature. This book was released on 2021-09-15 with total page 268 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Book Synopsis The Wheat Rusts — Breeding for Resistance by : Douglas R. Knott
Download or read book The Wheat Rusts — Breeding for Resistance written by Douglas R. Knott and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 213 pages. Available in PDF, EPUB and Kindle. Book excerpt: The idea for this book was conceived by the late Dr. Irvine A. Watson of the University of Sydney, and he developed the first outline. I was then invited by Dr. Watson to share in its writing. Unfortunately, shortly there after, recurring heart problems forced him to curtail his activities and with draw from the project. He died before the book could be completed. Dr. Watson's intention was to produce a very practical book that would provide wheat breeders with all of the information necessary to breed success fully for resistance to the three wheat rusts: leaf rust, stem rust, and yellow rust. It was intended to be very specific in describing procedures to be used and at the same time provide all of the necessary theoretical background. I hope that I have been successful in meeting these objectives. The book assumes that the reader has some knowledge of plant pathology, genetics, and plant breeding. Extensive use has been made of the literature, but it was not possible to cite all of the papers on a given topic. In making a choice, an attempt was made to choose key papers or more recent papers that provided references to the earlier literature. Acknowledgements This book was written partly at the University of Saskatchewan and partly at the University of California, Davis, while I was on a sabbatical leave.

Book Synopsis Genetic mapping of resistance to race Ug99 of Puccinia graminis f. sp. tritici, diversity analysis and identification of stem rust resistance genes in Ethiopian tetraploid wheats by : Jemanesh Kifetew Haile
Download or read book Genetic mapping of resistance to race Ug99 of Puccinia graminis f. sp. tritici, diversity analysis and identification of stem rust resistance genes in Ethiopian tetraploid wheats written by Jemanesh Kifetew Haile and published by Cuvillier Verlag. This book was released on 2013-01-15 with total page 134 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ethiopia is the second largest wheat producer in the sub-Saharan Africa. The country is rich in genetic resources of tetraploid wheat and has suitable environments for wheat production. However, the country is a net importer of wheat particularly durum wheat (hard wheat). The demand for durum wheat is continuously increasing because of the new emerging food processing industries. But the productivity of wheat in Ethiopia is low due to biotic and abiotic stresses. Among the biotic factors, diseases particularly stem rust play a significant role in yield reduction. As a result of a recent spread of a new and highly virulent race of Puccinia graminis f. sp. tritici (Pgt), Ug99, stem rust is becoming a serious threat to wheat production in Ethiopia as well as in other East African and wheat producing countries. Therefore, it is important to identify new resistance sources and to apply marker assisted selection for sustainable and efficient control stem rust. The aims of the studies included in this thesis were (i) identification of QTL and test for epistatic effects in a segregating population for resistance to stem rust, (ii) identification of stem rust resistance (Sr) genes that are present in durum wheat (Triticum durum Desf.) varieties that were released in Ethiopia during the period 1966–2009 and tetraploid wheat landraces using linked/diagnostic molecular markers and (iii) Evaluation of genetic diversity and relationship pattern within and among these tetraploid wheat landraces and improved varieties based on SSR/STS markers including those linked with reported stem rust resistance genes and QTL. Across all the three experiments, our study demonstrates that there exist potential germplasm and strategies to combat the threat posed by Ug99 and its derivatives. These results provide useful information to wheat breeders in Ethiopia and other national and international programs, regarding the use of available landraces and released varieties for the enhancement of the genetic base of wheat germplsm. Particularly it will give an alarm for Ethiopian wheat breeders to broaden the genetic base of the varieties that will be released in the future since most of the varieties released for the last five decades have a narrow genetic base. In addition, our research provides a base of knowledge for future QTL and gene mapping conferring resistance to stem rust and the use of the linked markers in marker assisted selection.
