Aims and Scope
The book series is intended for readers ranging from advanced students to senior research scientists
and corporate directors interested in acquiring in-depth, state-of-the-art knowledge about research
findings and techniques related to all aspects of agricultural biotechnology. Although the previous
volumes in the series dealt with plant science and biotechnology, the aim is now to also include
volumes dealing with animals science, food science and microbiology. While the subject matter will
relate more particularly to agricultural applications, timely topics in basic science and biotechnology
will also be explored. Some volumes will report progress in rapidly advancing disciplines through
proceedings of symposia and workshops while others will detail fundamental information of an
enduring nature that will be referenced repeatedly.

Preface
Genetic erosion, that is the loss of genetic diversity, of the Earth's biological resources is
notoriously difficult to quantity, but few would disagree that the Twentieth Century has seen a
massive and exponential loss of native plant diversity in the Mediterranean Basin. This careless
eradication of species and loss of genetic diversity from a botanical and agricultural 'hot-spot' of
diversity is a result of human intervention and continues apace today. It can be directly linked to the
introduction of modern agricultural practices and lack ofs ustainable development, which in turn have
negative economic, political and social consequences for the region. Plant genetic diversity forms the
biological basis for sustainable agriculture and directly contributes to food security for the regions
growing human population, but while recent conservation efforts in the Mediterranean have had
beneficial effects, the still diminishing Mediterranean flora can accurately be described as a 'Flora in
Crisis'.
However, since the early 1960s there has been a movement to halt the loss of plant diversity
and enhance its utilisation. This initiative was under-scored by the Convention on Biological
Diversity that not only expounds the need to conserve biological diversity but links conservation to
exploitation and development for the benefit of all. Article 8 oft he Convention clearly states the need
to develop more effective and efficient guidelines to conserve biological diversity, while Article 9,
along with the F AO International Undertaking on Plant Genetic Resources, promotes a
complementary approach to conservation incorporating both in situ and ex situ techniques.
It has been argued that the most important component ofbiodiversity is the genetic diversity
of plants, those crop and forage species used to feed humans and livestock. Plant genetic diversity
in both cultivated and wild species provides the raw material for further selection and improvement,
and has enabled breeders to develop cultivars to feed to the expanding human population within the
Mediterranean region and throughout the temperate world. However, formal plant breeding is a
relatively recent activity, and farmers have been nurturing the crop and forage species that originated
in the Mediterranean Basin and North West Asia for millennia.
The careless eradication of species and loss of genetic diversity is threatening and clearly
impeding crop improvement. The Convention on Biological Diversity recognises the link between
conservation and sustainable utilisation, as well as the need to improve the efficiency of conservation
activities. As a result the Consultative Group on International Agricultural Research (CGIAR), which
has a major international responsibility for global food security, established the System-wide Genetic
Resources Programme (SGRP) to enhance the efficiency and effectiveness of the CGIAR's
contribution to Plant Genetic Resources for Food and Agriculture (PGRFA) conservation and
sustainable utilisation. The sixteen CGIAR centres currently hold about half a million accessions in
trust for humanity. To help increase transparency and ensure maximum use of conserved diversity,
the CGIAR published 'Biodiversity in Trust: Conservation and Use of Plant Genetic Resources in
CGIAR Centres' in 1997. This text reviewed the status of the CGIAR collections, providing details
of botany, distribution and agronomy ofthe most important PGRF A species. Although the CGIAR
system contains very large and significant collections of PGRF A species, their collections are not

exhaustive. The World Information and Early Warning System on Plant Genetic Resources
(WIEWS) database of the Food and Agriculture Organization of the United Nations, which contains
information on national PGRF A programmes, indicates that there are 6.1 million PGRF A accessions
held worldwide. Therefore, there is a need to further enhance transparency in a complementary
manner, by focusing attention on particular regions and plant families. As with the CGIAR volume,
we hope to stimulate more effective genetic conservation oflegume diversity in the Mediterranean
region, and ensure improved and sustainable utilisation.
Why legumes oft he Mediterranean? Leguminosae species are ofm ajor economic importance
(second only to the Gramineae), and the diverse herbaceous species of sub-family Papilionoideae
provide a particularly rich source of protein for human and animal foods. Numerous Leguminosae
species are exploited throughout temperate and tropical agro-ecosystems. Within the temperate
regions of the world, the highest concentration oflegume species is found in the Mediterranean (91
genera, 1,956 species and 495 subspecific taxa (Med-Checklist Database: Berendsohn, pers. comm.).
The Mediterranean Basin with South-West Asia is undoubtedly a "hot-spot" for legume PGRFA
diversity. It is the centre of diversity for the four major temperate legume crops: peas, chickpeas,
lentils and faba beans, which all originated in this region. The region also contains two ofN.I.
Vavilov's centres of major crop plant diversity. The Asia Minor Centre is important for Cicer
arietinum (secondary centre), Lens culinaris, L. orienta/is, Vicia ervilia, Pisum sativum, various
forage plants such as Medicago sativa, Trifolium re!l71pinatum, Trigonella foenum-graecum,
Onobrychis spp., Lathyrus cicera, and several Vi cia spp.; and the Mediterranean Centre is important
for Viciafaba, V. sativa, Lathyrus ochrus, large-seeded Cicer arietinum, Hedysarum coronarium
and Omithopus sativus. Therefore, legumes and the Mediterranean region are a vital resource for
world agriculture.
We have divided the book into four sections and 19 chapters. Section 1 introduces the
subjects of conservation and use oflegume diversity, the Mediterranean ecosystem and taxonomy of
legumes. Section 2 reviews the taxonomic and genetic diversity of legume species found in the
Mediterranean, largely based on generic summaries. Each chapter summarises generic taxonomy,
centre of diversity, ecogeographic distribution, genetic diversity distribution, conservation status,
conservation gaps and research needs. There is also a discussion of the importance of rhizobia to the
maintenance oflegume diversity. Section 3 reviews ex situ and in situ conservation activities in the
region, while Section 4 reviews how legume genetic diversity is currently being used both within the
Mediterranean and other regions of world where Mediterranean genetic resources are exploited.
Finally, in conclusion we attempt in an Afterword to summarise the future priorities for ex situ and
in situ plant genetic conservation for Mediterranean legumes and highlight some important
development in terms of utilisation.
It should be noted that the many chapters contain summaries of current ex situ gene bank
holdings. When editing this volume it was noted that in certain cases different figures are quoted for
the same taxa in a gene bank. As editors we could have standardised these figures, however, we
preferred to leave the figures as stated by the contributing authors. It should be remembered that any
figures included in a text oft his kind should be seen as being indicative rather than absolute, therefore
small variations in quoted figures have little consequence. By their dynamic nature, gene bank
holdings change regularly as accessions are added or lost. Therefore figures on current holding are

valid only for a short period, thus if accurate figures are required they should be obtained from the
collection managers or their web sites.

We also thank ILDIS for supplying data on the distribution oflegume species.
We have attempted to encourage our contributors to look forward rather than simply
reviewing past and current activities. As highlighted above, any text which details current germ plasm
holding or locates current conservation sites alone is in the long term doomed to lose relevance as
these data are by their nature ephemeral; in this sense both ex situ and in situ conservation activities
are dynamic. However, the discussion contained within will, it is hoped, identify sources of genetic
erosion, locate taxonomic and genetic diversity that is not conserved, and promote more efficient
utilisation of conserved material.
