Maintaining food security in the face of human population increase and climate change is one of the critical challenges facing us in the 21st Century. Utilisation of the full range of agrobiodiversity will be a necessary tool in addressing this challenge. In this book a team of international contributors review all aspects of utilization and conservation of crop wild relative (CWR) and landrace (LR) diversity as a basis for crop improvement and future food security. This book will appeal to a wide array of specialists and postgraduate students, such as those working in the fields of agrobiodiversity conservation and use, conservation, ecology, botany, genetics, plant breeding and agriculture.

Capturing Wild Relative and Landrace Diversity for Crop Improvement

Enhancing Crop Genepool Use

Pea is an important temperate region pulse, with feed, fodder and vegetable uses. It originated and was domesticated in Middle East and Mediterranean regions, and formed important dietary components of early civilizations. Although Pisum is a very small genus with two or three species, it is diverse and structured, reflecting taxonomy, ecogeography and breeding gene pools. This diversity has been preserved in collections totalling about 90,000 accessions. Core collections have been formed, facilitating phenotypic and agronomic evaluations. However, only 3% of ex situ collections are wild Pisum sp., with substantially larger diversity. The genomic resources allow initiation of association mapping, linking genetic diversity with trait manifestation. So far, only a small part of wild gene pools have been exploited in breeding for biotic and abiotic stresses. Current genomic knowledge and technologies can facilitate allele mining for novel traits and incorporation from wild Pisum sp. into elite domestic genetic backgrounds.

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.

Plant Genetic Conservation

Sarita Jane Bennett

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.

Plant Genetic Resources of Legumes in the Mediterranean

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.

The Ex Situ Conservation of Plant Genetic Resources

Based on the 2010 conference "Towards the establishment of genetic reserves for crop wild relatives and landraces in Europe", this book is the cutting edge discussion of agrobiodiversity conservation. By considering the benefits of understanding and preserving crop wild relatives and landraces, it encompasses issues as wide-ranging and topical as habitat protection, ecosystem health and food security. Focusing on Europe, but globally relevant, Agrobiodiversity Conservation is ideal for postgraduate students of conservation and environmental studies, conservation professionals, policy makers and researchers.
