Plant diversity sustains all animal life, and the genetic diversity within plants underpins global food security. This text provides a practical and theoretical introduction to the strategies and actions to adopt for conserving plant genetic variation, as well as explaining how humans can exploit this diversity for sustainable development. Notably readable, it initially offers current knowledge on the characterization and evaluation of plant genetic resources. The authors then discuss strategies from in situ and ex situ conservation to crop breeding, exploring how these can be used to improve food security in the face of increasing agrobiodiversity loss, human population growth and climate change. Each chapter draws on examples from the literature or the authors' research and includes further reading references. Containing other useful features such as a glossary, it is invaluable for professionals and undergraduate and graduate students in plant sciences, ecology, conservation, genetics and natural resource management.

The papers included in this Special Issue address a variety of important aspects of plant biodiversity and genetic resources, including definitions, descriptions, and illustrations of different components and their value for food and nutrition security, breeding, and environmental services. Furthermore, comprehensive information is provided regarding conservation approaches and techniques for plant genetic resources, policy aspects, and results of biological, genetic, morphological, economic, social, and breeding-related research activities. The complexity and vulnerability of (plant) biodiversity and its inherent genetic resources, as an integral part of the contextual ecosystem and the human web of life, are clearly demonstrated in this Special Issue, and for several encountered problems and constraints, possible approaches or solutions are presented to overcome these.

It is a distressing truism that the human race during the last millennium has caused the exponential loss of plant genetic diversity throughout the world. This has had direct and negative economic, political and social consequences for the human race, which at the same time has failed to exploit fully the positive benefits that might result from conserving and exploiting the world's plant genetic resources. However, a strong movement to halt this loss of plant diversity and enhance its utilisation for the benefit of all humanity has been underway since the 1960's (Frankel and Bennett, 1970; Frankel and Hawkes, 1975). This initiative was taken up by the Convention on Biological Diversity (CBD, 1992) that not only expounds the need to conserve biological diversity but links conservation to exploitation and development for the benefit of all. Article 8 of the Convention clearly states the need to develop more effective and efficient guidelines to conserve biological diversity, while Article 9, along with the FAO International Undertaking on Plant Genetic Resources, promotes the adoption of a complementary approach to conservation that incorporates both ex situ and in situ techniques.

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.

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.

However, the transition from primitive to 'advanced' cultivars has had the effect of narrowing the genetic base. This has happened in two distinct ways: (1) selection for relative uniformity, resulting in 'pure' lines, multi lines, single or double hybrids, etc. ; and (2) selection for closely defined objectives. Both of these processes have resulted in a marked reduction in genetic variation. At the same time, there has been a tendency to restrict the gene pool from which parental material has been drawn. This is a result of the high level of productivity achieved when breeding within a restricted but well-adapted gene pool, and of breeding methods which have made it possible to introduce specifically desired improvements, such as disease resistance and quality characteristics, into breeding stocks with a minimum of disturbance to genotypic structure. Developments in agriculture, such as intensive mechanization, the widespread application of fertilizers and the use of herbicides, fungicides and pesticides, have created a situation whereby a few, selected high yielding cultivars may be grown over large parts of the earth, so further contributing to a decline in crop genetic diversity. This process is under way in all countries, both developed and developing, and unfortunately in cludes some of the richest primary and secondary gene centres of several important food crops.
