The period following the second world war has witnessed an expanding commitment to incr~ased food production in tropical countries. Public and private initiatives at the national and international levels have led to the creation of programs geared specifically towards the improvement of food crops in tropical conditions. Examples of this increased commitment are the network of international agricultural research centers and numerous bilateral aid projects. As a consequence, crop improvement has become a truly worldwide endeavor, relying on an international network of institutions and collaborators. This holds also for Phaseolus beans. Following the discovery of the Americas, Phaseolus beans became distributed on all six continents. Yet, until not so long ago, most of the research on Phaseolus improvement took place in developed countries. In recognition of the nutritional importance of Phaseolus beans in developing countries, this has changed considerably in the last years, principally perhaps through the activities of the Centro Internacional de Agricultura Tropical (CIAT) and the International Board for Plant Genetic Resources (IBPGR). Consequently, the scope of the research on Phaseolus has broadened considerably and the number of Phaseolus researchers is larger than ever before.

In this chapter, we lead the reader through several topics related to common bean germplasm, including crop dissemination across the Old World, landraces developed by farmers, characterization and safeguard of germplasm. These topics are attracting a great deal of attention, especially in recent years, when the international community has become increasingly aware of the relevance of safeguarding plant genetic resources. Early studies were mainly aimed at performing exploratory analyses of agro-morphological traits, with the goal of improving yield and pest resistance. Moreover, phaseolin variation was studied to check the distribution of the two common bean gene pools. The recent development of DNA-based markers has allowed significant improvement in knowledge on genetic variation within the European germplasm, as well as the capacity to trace its divergence from the American germplasm. The different strategies applied to safeguard the European germplasm are described together with their drawbacks.

Common Bean (Phaseolus vulgaris L.) is cultivated all over Kosova in the home gardens and also in the fields. This country, with a very variable topography and climate is depending on a diversity of the landraces. This study showed varieties of common bean landraces which was gathered for a National Gene Bank. Five regions with 15 localities and five samples were collected at each locality. The varied altitude, climatic influences, and soils within Kosovo provide a wide diversity of micro-habitats to which plant and animal species are adapted. Genetic resources in general are spread throughout the word. It is always of interest to investigate in different countries. Kosova is a small geographical area in the heart of South East Europe with many characteristics, beginning in the cultural tradition, economical situation, historical past, and climatic condition, etc. Perhaps these characteristics can give rise to a specific trait that can be useful in future

Genomics of Plant Genetic Resources

Our lives and well being intimately depend on the exploitation of the plant genetic resources available to our breeding programs. Therefore, more extensive exploration and effective exploitation of plant genetic resources are essential prerequisites for the release of improved cultivars. Accordingly, the remarkable progress in genomics approaches and more recently in sequencing and bioinformatics offers unprecedented opportunities for mining germplasm collections, mapping and cloning loci of interest, identifying novel alleles and deploying them for breeding purposes. This book collects 48 highly interdisciplinary articles describing how genomics improves our capacity to characterize and harness natural and artificially induced variation in order to boost crop productivity and provide consumers with high-quality food. This book will be an invaluable reference for all those interested in managing, mining and harnessing the genetic richness of plant genetic resources.

Reviewing the relevant scientific and technical literature, this work summarizes the current state-of-the-art knowledge related to gene flow and introgression (the permanent incorporation of genetic information from one set of differentiated populations into another) between genetically modified crops and their wild relatives. They analyze the biological framework for protecting the genetic integrity of indigenous wild relatives of crops in centers of crop origin and diversity, focusing on the issues of emission, dispersal, and deposition of pollen and/or seed; the likelihood and extent of gene flow from crops to wild relatives; and stabilization and the spread of traits in wild species. The material is organized into crop chapters, each of which covers general biological information of the crop; the most important crop wild relatives together with information about their ploidy levels, diverse genomes, centers of origin, and geographic distribution; the crop's potential for hybridization with its wild relatives; pollen flow studies related to pollen dispersal distances and hybridization rates; the current state of the genetic modification technology regarding that crop; and research gaps. The crop chapters discuss banana and plantain; barley; canola and oilseed rape; cassava, manioc, and yucca; chickpea; common bean; cotton; cowpea; finger millet; maize and corn; oat; peanut and groundnut; pearl millet; pigeonpea; potato; rice; sorghum; soybean; sweet potato, batata, and camote; and wheat and bread wheat.

Grain legumes play significant and diverse role in the farming systems and provide nutrition security to the largely vegetarian and relatively poorer people around the world. These are ideal crops for achieving three simultaneous developmental goals viz. reducing poverty, improving human health and nutrition and enhancing ecosystem resilience. Globally, grain legumes are the second most important crop group next only to cereals but a large proportion of area of it is under rainfed-low input systems as compared to cereals contributing to lower yields. The other important factor responsible for reduced yield in grain legumes is the narrow genetic base of the present day pulse varieties. In order to break the yield barriers of these cultivars, new sources of genes/ alleles need to be identified and suitably incorporated into the adapted background. The information on various aspects of grain legume improvement although has been considerable in the recent past, these information are highly scattered and not available at one place. The present book consists of comprehensive and latest crop-wise information on important grain legumes of the world including their distribution, gene pool, systematics, status of genetic and genomic resources, production constraints, traits of importance, crop improvement methodologies - both conventional as well as contemporary and future strategies to be adopted for comprehensive grain legume improvement in various agro-ecological target areas of the globe. The chapters have been contributed by eminent crop experts from across the world engaged in research in their respective crops for the past several years thus providing a rare insight into the crop specific constraints and prospects drawing from their rich overall experience. The book therefore will be a useful source of information to the grain legume researchers, students, policy planners and developmental experts alike.
