The recent development of ideas on biodiversity conservation was already being considered almost three-quarters of a century ago for crop plants and the wild species related to them, by the Russian geneticist N.!. Vavilov. He was undoubtedly the first scientist to understand the impor tance for humankind of conserving for utilization the genetic diversity of our ancient crop plants and their wild relatives from their centres of diversity. His collections showed various traits of adaptation to environ mental extremes and biotypes of crop diseases and pests which were unknown to most plant breeders in the first quarter of the twentieth cen tury. Later, in the 1940s-1960s scientists began to realize that the pool of genetic diversity known to Vavilov and his colleagues was beginning to disappear. Through the replacement of the old, primitive and highly diverse land races by uniform modem varieties created by plant breed ers, the crop gene pool was being eroded. The genetic diversity of wild species was equally being threatened by human activities: over-exploita tion, habitat destruction or fragmentation, competition resulting from the introduction of alien species or varieties, changes and intensification of land use, environmental pollution and possible climate change.

Genes in the Field: Conserving Plant Diversity on Farms is a comprehensive collection of papers focusing on agricultural conservation and diversity issues throughout the world. Recently, regional and local farm seed variety has been reduced because of increased population, agricultural science and technology and the integration of the world's many diverse cultures. Because of this, diversity on individual farms across wide regions is threatened by modern crop varieties that have been bred for broad adaptation, resistance to disease, and other risk factors such as their ability to better use water, fertilizer, and higher yields. The concern of the farmers to maintain production levels and income often seems incompatible with those whose focus is on the maintenance of viable and sustainable ecosystems and maintaining genetic diversity. Exploring and understanding these different concerns is an essential starting point for answering some of the key questions about the implementation of "on farm" conservation and the role of local cultivators in sustainable development.

This collection starts by reviewing key issues such as valuing, identifying and monitoring plant genetic diversity. The book goes on to assess advances in in-situ and on-farm strategies for protecting crop wild relatives and landraces. Chapters cover topics such as local strategies for preserving crop genetic resources, in-situ management of wild plant populations, monitoring genetic diversity and collecting wild varieties. The book also discusses community-based conservation strategies, participatory plant breeding programmes and seed systems to ensure farmer access to improved varieties. Part 4 reviews key challenges facing ex-situ collections such as genebanks, including improved storage and conservation techniques. Parts 5 and 6 assesses improvements in characterising and evaluating plant genetic resources such as DNA-based screening and phenotyping, as well as ways of improving the quality and exchange of information and germplasm for use in breeding improved varieties.

The conservation of crop genetic resources is one of the important elements in efforts to sustainably increase agricultural production in low-income countries, and to guarantee long-term food security, especially for the low-income population groups in these countries. Horticultural crops, as high-value crops, have an important role to play in revitalizing rural economies and can add significantly to national economies. Moreover, horticulture provides more than twice the number of jobs compared to traditional cereal crop production, and the shifting of conventional agriculture towards high-value horticulture has increased employment opportunities in developing countries. To exploit this potential, researchers need a vast array of horticultural genetic resources and information on new traits. Horticultural crops, which are only a part of PGRFA (Plant Genetic Resources for Food and Agriculture), are characterized by a wide and varied range of species. In fact, there are five major horticultural crop groups: fruit and nut crops, vegetables, food legumes, roots and tubers, and lastly the ornamental and medicinal group. In this context, the present book provides a comprehensive overview of the current state of conservation and utilization of horticultural genetic resources, addressing contemporary approaches to conservation in connection with different technologies, including biotechnological approaches as practised in India and in some cases, globally. It includes a brief chapter on the unique nature of horticultural genetic resources, providing a rationale for viewing them as being distinct from field crop genetic resources. Subsequent chapters share insights on protocols for the conservation of selected horticultural crops ex situ, and focus on the increased need to complement these efforts with in situ conservation approaches. Geospatial tools are also briefly described, emphasizing their utility with regard to mapping and managing resources. The book also explores the wild gene pool in horticulture crops; discusses legal aspects related to horticultural genetic resources and biotechnological aspects; and describes the key aspects of sustainable management and replenishment. Given its scope, the book offers a valuable resource for all horticulturists, graduate students, researchers, policymakers, conservationists, and NGOs engaged in horticulture in particular and biodiversity in general.

The volume on oilseed crops is developed as a part of a series on “Handbook of Agrobiodiversity: Conservation and Use of Plant Genetic Resources”. The handbook would function as a ready reference book for availability of PGR globally, along with specific source, wherefrom they can be procured, and used breeding programs, particularly to overcome various crop production constraints and to improve productivity and quality. The volume on floriculture and ornamental plants will be the source of basic information on origin and evolution and global dispersal of cultivated species of ornamentals. Presently, floriculture has established its credibility in improving income through increased productivity, generating employment and in enhancing exports. All research and developmental activities on ornamental crops are essentially multi-disciplinary in nature recognizing local issues as well as country issue. Floriculture is developing as an area of high technology based frontier interdisciplinary area on scientific excellence. Floriculture has progressed both scientifically and commercially due to concentrated efforts made on multidisciplinary research. It is developing as an area of high technology based frontier interdisciplinary area on scientific excellence. The volume will contain all information about different ornamentals. This shall be put together to develop a complete documentation of the results of the research and demonstrations conducted by different scientists. The volume will provide an illustrated horto-taxonomical account of important ornamental species and cultivars, germplasm status and their usages, propagation, nursery management, techno-economics, conventional breeding, induced mutagenesis, new varieties, cytogenetics, tissue culture, characterization of varieties, dehydration of flowers etc. This volume will give a coherent and concise account on recent developments. It will deal with all the important and relevant aspects of floriculture. The publication of this volume is planned to reveal multifarious activities done on different aspects of floriculture so that innovations made so far can be used judiciously for this sector. This book shall provide authoritative review account of many aspects of current interest and progress in the field of floriculture. The topics included in the book are interdisciplinary and cater not only classical floriculture but also relevant modern aspects. The book will provide valuable data on different aspects and will be widely accepted by by professional scientists, researchers, teachers, students, floriculturists, technocrats and planners. The volume will be an invaluable asset to floriculture scientists.

Demonstrating the shortcomings of current policy and legal approaches to access and benefit-sharing (ABS) in the Convention on Biological Diversity (CBD), this book recognizes that genetic resources are widely distributed across countries and that bilateral contracts undermine fairness and equity. The book offers a practical and feasible regulatory alternative to ensure the goal of fairness and equity is effectively and efficiently met. Through a legal analysis that also incorporates historic, economic and sociological perspectives, the book argues that genetic resources are not tangible resources but information. It shows that the existing preference for bilateralism and contracts reflects resistance on the part of many of the stakeholders involved in the CBD process to recognize them as such. ABS issues respond very well to the economics of information, yet as the author explains, these have been either sidelined or overlooked. At a time when the Nagoya Protocol on ABS has renewed interest in feasible policy options, the author provides a constructive and provocative critique. The institutional, policy and regulatory framework constitute "bounded openness" under which fairness and equity emerge.

Loss of biodiversity is among the greatest problems facing the world today. Conservation and the Genetics of Populations gives a comprehensive overview of the essential background, concepts, and tools needed to understand how genetic information can be used to conserve species threatened with extinction, and to manage species of ecological or commercial importance. New molecular techniques, statistical methods, and computer programs, genetic principles, and methods are becoming increasingly useful in the conservation of biological diversity. Using a balance of data and theory, coupled with basic and applied research examples, this book examines genetic and phenotypic variation in natural populations, the principles and mechanisms of evolutionary change, the interpretation of genetic data from natural populations, and how these can be applied to conservation. The book includes examples from plants, animals, and microbes in wild and captive populations. This second edition contains new chapters on Climate Change and Exploited Populations as well as new sections on genomics, genetic monitoring, emerging diseases, metagenomics, and more. One-third of the references in this edition were published after the first edition. Each of the 22 chapters and the statistical appendix have a Guest Box written by an expert in that particular topic (including James Crow, Louis Bernatchez, Loren Rieseberg, Rick Shine, and Lisette Waits). This book is essential for advanced undergraduate and graduate students of conservation genetics, natural resource management, and conservation biology, as well as professional conservation biologists working for wildlife and habitat management agencies.
