Book Description
The genus Lathyrus is wide spread in adverse environmental conditions. The main constrain of using Lathyrus is the presence of neurotoxin compound (ODAP), which causes Lathyrism for human and animals. To overcome this constrain, genetic resources must be mined for the genes conferring good agronomic traits and less amount of ODAP. Assessment of genetic diversity is the first priority in this context. Great homogeneity was observed in chromosome number of Lathyrus spp. The variation was only in karyptype characters and chromosome size, allowing the differentiation of several accessions. There were variations in seeds weight and protein content between or within species. The small seeds were most frequent in accessions of Lathyrus sativus from Asia and Africa, suggesting the center of origin Indian Subcontinent and Eastern Africa. Electrophoretic analysis showed inter and intra-specific variations. Isoenzymatic analysis revealed that the total alleles of isozymes were 34; genetic diversity was dividing between intera-accessions and inter-accessions; and the high level of gene flow revealed could be due to the high percent of out-crossing.

Book Description
Genetic erosion, that is, the loss of native plant and genetic diversity has been exponential from the Mediterranean Basin through the Twentieth century. This careless eradication of species and genetic diversity as a result of human activities from a 'hot-spot' of diversity threatens sustainable agriculture and food security for the temperate regions of the world. Since the early 1900s there has been a largely ad hoc movement to halt the loss of plant diversity and enhance its utilisation. The Convention on Biological Diversity and Food and Agriculture Organisation of the United Nations International Undertaking on Plant Genetic Resources, both highlight the need to improve conservation methodologies and enhance utilisation techniques. It has been argued that the most important component of biodiversity is the genetic diversity of crop and forage species used to feed humans and livestock. These cultivated and related wild species provides the raw material for further selection and improvement. Leguminosae species are of major economic importance (peas, chickpeas, lentils and faba beans, as well as numerous forage species) and provide a particularly rich source of protein for human and animal foods. Their distribution is concentrated in the Mediterranean region and therefore the improvement of their conservation and use in the region is critical. This text is designed to help ensure an adequate breadth of legume diversity is conserved and to help maximise the use of that conserved diversity. The subjects of conservation and use of legume diversity, the Mediterranean ecosystem and taxonomy of legumes are introduced. Generic reviews of the taxonomy, centre of diversity, ecogeographic distribution, genetic diversity distribution, conservation status, conservation gaps and future research needs are provided, along with a discussion of the importance of rhizobia to the maintenance of legume diversity. Current ex situ and in situ conservation activities as well current legume uses are reviewed. In conclusion future priorities for ex situ and in situ plant genetic conservation and use of Mediterranean legumes are highlighted. All contributors look forward rather than simply reviewing past and current activities and therefore it is hoped that the identification of genetic erosion, location of taxonomic and genetic diversity and promotion of more efficient utilisation of conserved material will be enhanced.

Book Description
The Beans and the Peas: From Orphan to Mainstream Crops presents a comprehensive literature resource on the most important food legume crops previously known as "orphans," but which are increasingly becoming mainstream as their production opportunities have been improved through genetic improvement and biotechnology, and their role as an important nutrient source gains urgency. This book focuses on 12 important food legumes and discusses all relevant aspects on their economic importance, crop statistics, botany, and their general description. It also provides exhaustive information on plant genetic resources and their use, genetic improvement, resistance to biotic and abiotic stresses, improved varieties, agronomy, seed system, and use of information and communication tools in each individual food legume.Development of innovative biotechnological tools, genetic transformation, and the genome sequencing information has also been covered in each chapter providing the readers with state-of-the-art information on pulses. All chapters have been supported by relevant figures, illustrations, and tables, which make the contents accessible and easy to understand.Each of the chapters has been authored by globally known scientists/researchers presenting up-to-date information on various aspects of food legumes. This book provides a current and comprehensive treatise to the readers and will be tremendously helpful in furthering their academic and research pursuits. Provides a single-volume resource on the most important food legumes having a prominent role in food and nutritional security Written by experts with a focus on providing foundational information for further research and development Presents both theoretical aspects and application-based case studies Supported by relevant figures, illustrations, and tables

Book Description
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

Book Description
Cool season grain legumes including pea, faba bean, lentil, chickpea, and grass pea are extensively grown in many parts of the world. They are a primary source of proteins in human diet. This volume deals with the most recent advances in genetics, genomics, and breeding of these crops. The "state of the art" for the individual crops differs; howeve
