The Search For Wild Relatives Of Cool Season Legumes

​The study of origin and domestication of legumes described in this book emerged when it became apparent that while this kind of information is adequate for cereals, the pulses lagged behind. At the end of the 1960s the senior author initiated a study on the chickpea's wild relatives followed by similar attempts for broad bean, fenugreek, common vetch, bitter vetch, and lentil. The junior author joined the project in the late 1980s with a study of the genetics of interspecific hybrid embryo abortion in lentil and later has extensively investigated chickpea domestication and wild peas. While this book mainly describes our research findings, pertinent results obtained by others are also discussed and evaluated. Studying the wild relatives of legumes included evaluation of their taxonomic status, their morphological variation, ecological requirements, exploration of their distribution, and seed collection in their natural habitats. Seeds were examined for their protein profile as preliminary hints of their affinity to the cultigens and plants grown from these seeds were used for establishing their karyotype, producing intra- and interspecific hybrids and analyses of their chromosome pairing at meiosis and fertility. The aim of these investigations was the identification of the potential wild gene pool of the domesticated forms. Assessment of genetic variation among accessions, particularly in the genus Lens, was made by isozymes and chloroplast DNA studies. The main findings include the discovery of the chickpea wild progenitor; studies of lentil in three crossability groups; wild peas proceeded in two lines of study; faba bean and fenugreek and their wild progenitors have not yet been identified; common vetch and its related form were treated here as an aggregate (A. sativa); we found gene flow between members of different karyotypes is possible; bitter vetch and its relation to the domesticated form were established by breeding experiments.

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

The goal of the Second International Food Legume Research Conference held in Cairo, Egypt was to build on the success of the first conference held nearly 6 years earlier at Spokane, Washington, USA. It was at that first conference where the decision was made to hold the second Conference in Egypt and so near the ancestral home of these food legume crops. It has been a long held view that the cool season food legumes had their origin in the Mediterranean basin and the Near-east arc, and there is little doubt that food legumes were a staple food of the ancient Egyptian civilization. The cool season food legumes have the reputation for producing at least some yield under adverse conditions of poor fertility and limited moisture, i. e. , in circumstances where other crops are likely to fail completely. Yields of cool season food legumes are particularly poor in those regions where they are most important to local populations. The influx of more profitable crops such as wheat, maize, and soybeans have gradually relegated the food legumes to marginal areas with poor fertility and limited water which exposes them to even greater degrees of stress. In the past two decades, production of food legumes has declined in most of the developing countries while at the same time it has expanded greatly in Canada, Australia, and most notably in Turkey.

The genesis of the International Food Legume Research Conference (IFLRC) can be traced back to 1983 - and so this Volume, the Proceedings of that Conference, has had a gestation period of close to five years. Professor Norman Simmonds, the perennial Book Review Editor of Experimental Agriculture, has expressed the opinion (vol. 22, p. 201, 1986) that "Many symposial volumes are just plain awful!" Elsewhere (Nature vol. 312, pp. 201-2, 1984), Anthony Watkinson - then a Commissioning Editor at Oxford University Press has described several reasons which have led him to believe that "Conference proceedings - symposia - are generally disliked . . . . To put it mildly, this type of publication has a bad name". The problems, from an author's perspective, of contributing to any many-authored publication are aired in an exchange of correspondence in Biologist (vol. 30, pp. 123 and 180, 1983; and vol. 31, pp. 3 and 69,1984). And from the editor's viewpoint, D. J. Weatherall - then Nuffield Professor of Clinical Medicine at the University of Oxford - has described (Nature vol. 317, p.

The first book in this new series discusses grain legumes, which rank only second to cereals in supplying calories and protein to the world's population. With each chapter written by an internationally renowned scientist, the book reviews the role of alien germplasm for the domestication of each major legume crop. Discussion for each crop covers or

Lexicon of Pulse Crops integrates botanical and linguistic data to analyze and interpret the grain legume significance from the earliest archaeological and written records until the present day. Aimed at both agronomic and linguistic research communities, this book presents a database containing 9,500 common names in more than 900 languages and dialects of all ethnolinguistic families, denoting more than 1,100 botanical taxa of 14 selected pulse crop genera and species. The book begins with overviews of the world’s economically most important grain legume crops and their uncultivated relatives, as well as the world’s language families with their inner structure, including both extinct and living members. The main section of the text presents 14 specialized book chapters covering Arachis, Cajanus, Cicer, Ervum, Faba, Glycine, Lablab, Lathyrus, Lens, Lupinus, Phaseolus, Pisum, Vicia, and Vigna. They provide the reader with extensive lists of the botanically accepted species and subtaxa and surveys lexicological abundance in all world’s ethnolinguistic families, comprising extinct and living as well as natural and constructed languages, while the vernacular names for the most significant taxa are presented in comprehensive tables. Each of these chapters also presents the existing etymologies and novel approaches to deciphering the origins of common names, accompanied by one original color plate depicting possible root evolutions in the form of corresponding pulse crop plants.

In the proposed edited book, we will highlight the importance of various potential traits of crop wild relatives which are yet to be properly harnessed for designing future climate-resilient grain legumes.

Chickpeas, faba beans and lentils are important pulse crops in the Mediterranean regi on and Mi ddl e East, where thei r hi gh protei n seed nutritionally complement cereal grain in the human diet. The by-products of these crops serve as a valuable feed for animals. Thanks to their ability to fix atmospheric nitrogen, the inclusion of these crops in the cropping system helps in the maintenance of the productivity of the soil and reduces the dependence of the farmer on fertilizer nitrogen to realise good yields. Being the site of original domestication of these legumes, the Fertile Crescent is bel ieved to possess their vast genetic diversity. In order to prevent the erosion of this genetic di'/ersity and to preserve it for posterity, it is necessary that a major effort is made for its expeditious collection, evaluation, documentation and safe storage. The International Center for Agricultural Research in the Dry Areas (ICARDA) being located in the Fertile Crescent has, within its mandate, the responsibility to act as a world centre for the work on the genetic resources of kabuli chickpeas, faba beans and lentils. The International Board of Plant Genetic Resources (IBPGR) has been strongly supporting ICARDA in this important activity.
