Book Description
A range of cultivars and lines of soft wheat (Triticum aestivum L.) as well as one species of wild wheat. Three parental genotypes representing major wheat cultivars harvested in Egypt and Kazakhstan. Field research was carried out under conditions of Egypt and Kazakhstan throughout three vegetative periods (Kazakhstan, 2007; Egypt, 2007; Kazakhstan, 2008). Morphological characteristics of chosen wild, domesticated and hybrid wheats (F1 and F2); mid-parents heterosis; degree of heritability; molecular genetic characteristic of parents; effect of salt concentrations on wheat parents and their hybrids during germination; grains protein patterns; input of peroxidase enzyme in salt tolerance and effect of Triton on productivity of Egyptian wheat cultivars. The results of present dissertational work may be implied as a material for breeding programmes aimed at obtaining new genetic resources; for obtaining the data on genetic diversity at initial hybridization steps to effective breeding; the results of present dissertation provide for stock database and a set of research measures to conduct further analysis of biochemical and genetic bases for wheat salt tol

Book Description
Wheat (Triticum L.), an annual herbaceous plant in Poacae (Gramineae) family, settles in the Triticeae (Hordeae) subfamily. The grasses (Poaceae Barnhart) are the fifth largest (monocotyledonous flowering) plant family and of great importance for human civilization and life. Cereal crops such as maize, wheat, rice, barley, and millet are the domesticated ones in the family. It is still the most vital economical plant family in modern times, providing food, forage, building materials (bamboo, thatch), and fuel (ethanol). Wheat has many accessions in national and international gene banks. The estimated number of wheats by FAO in 2010 is 856,000, and, followed by rice (774,000), and barley (467,000). However, the recent consumer's (misdirected) focus on gluten content and nutritional value urges scientists to reexamine their knowledge about wheat (i.e., origin, evolution, and general and special quality characteristics), as well as their wild relatives and landraces for newer possible genetic resources. Cultured or non-cultured ancestral wheats: einkorn, emmer, wild emmer, spelt, macha, and vavilovii are still limitedly grown on the higher areas in Turkey, Italy, Germany, Morocco, Israel, and Balkan countries. They are exploited mostly for their desired agronomic, and specific quality. In some cultures, wheat species are believed to be therapeutic, with bioactive compounds that reduce and inhibit stubborn illnesses such as diabetes, cancer, Alzheimer, and cardiovascular diseases. In this book, we summarize the importance of ancestral wheat species, and provide a prospect for their future with special considerations in terms of species conservation and improvement.

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.

Book Description
Wild emmer is the progenitor of most cultivated wheats and thus an important source of wheat improvement. This book draws the results from multidisciplinary studies on the ecological, genetic, genomic, agronomic, and evolutionary aspects of wild emmer, conducted at many labs around the world. It is divided into the following parts: Origin and Evolution of Wheat - Population Genetics of Wild Emmer Wheat at the Protein and DNA Levels - Genetic Resources of Wild Emmer for Wheat Improvement - Genome Organization and Genetic Mapping - Conclusions and Prospects. The authors describe the evolution of wild emmer as a model organism of a selfer in evolutionary biology, and its rich potential genetic resources for wheat improvement.

Book Description
This anchor volume to the series Managing Global Genetic Resources examines the structure that underlies efforts to preserve genetic material, including the worldwide network of genetic collections; the role of biotechnology; and a host of issues that surround management and use. Among the topics explored are in situ versus ex situ conservation, management of very large collections of genetic material, problems of quarantine, the controversy over ownership or copyright of genetic material, and more.

Book Description
This work is a comprehensive history of wheat across all its main areas of production. New techniques such as in vitro culture now enable the development of a greater level of understanding of the genetics of wheat.
