Gene Pool Diversity and Crop Improvement by Vijay Rani Rajpal,S. Rama Rao,S.N. Raina Pdf

The world population is estimated to reach to more than 10 billion by the year 2050. These projections pose a challenging situation for the agricultural scientists to increase crops productivity to meet the growing food demands. The unavailability and/or inaccessibility to appropriate gene pools with desired traits required to carry out genetic improvement of various crop species make this task formidable for the plant breeders. Incidentally, most of the desired genes reside in the wild genetic relatives of the crop species. Therefore, exploration and characterization of wild genetic resources of important crop species is vital for the efficient utilization of these gene pools for sustainable genetic improvements to assure food security. Further, understanding the myriad complexities of genic and genomic interactions among species, more particularly of wild relatives of crop species and/or phylogenetically distant germplasm, can provide the necessary inputs to increase the effectiveness of genetic improvement through traditional and/or genetic engineering methods. This book provides comprehensive and latest insights on the evolutionary genesis of diversity, access and its utilization in the evolution of various crop species. A comprehensive account of various crops, origin, exploitation of the primary, secondary and tertiary gene pools through breeding, biosystematical, cytogenetical and molecular phylogenetical relationships, and genetic enhancement through biotechnological interventions among others have been provided as the necessary underpinnings to consolidate information on the effective and sustainable utilization of the related genetic resources. The book stresses upon the importance of wild germplasm exploration, characterization and exploitation in the assimilation of important crop species. The book is especially intended for students and scientists working on the genetic improvement of crop species. Plant Breeders, Geneticists, Taxonomists, Molecular Biologists and Plant Biotechnologists working on crop species are going to find this book very useful.

Genes from the Wild by Robert Prescott-Allen,Christine Prescott-Allen Pdf

Tomatoes could not be grown commercially without the help of their wild relatives. A single wild species of rice has helped double rice production in Asia. Wild silk-worms are enabling India to expand its silk industry. A wild carp with resistance to cold has been used to extend Soviet carp production further into the north. Wild genetic resources - the heritable characteristics of wild plants and animals - are used increasingly to improve domesticated crops and livestock and as new sources of food and of raw materials. But habitat destruction, over-exploitation and competition from introduced species is destroying many gene pools even before they have been identified. Genes from the Wild describes the growing contribution of wild genetic resources to the production of food and raw materials, describes their characteristics, explains the benefits and problems of using them and outlines the ways in which they are threatened and the measures being taken to conserve them.

Chickpea: Crop Wild Relatives for Enhancing Genetic Gains by Mohar Singh Pdf

Chickpea: Crop Wild Relatives for Enhancing Genetic Gains explores aspects related to critical analysis on factors responsible for narrow genetic base of chickpea productions including domestication bottleneck, the level of diversity present in different cultivated and wild species, the uniqueness and usefulness of potential gene sources available and maintained in production systems across the globe, the level of genetic erosion both at landrace and species level over time and space etc. Despite considerable international investment in conventional breeding, production of chickpea has not yet been significantly improved beyond that achieved through its normal single domestication event and high self-pollination rate. Total annual pulse production of ~12 million tons (FAO 2016) is far below actual potential. Susceptibility to both biotic and abiotic stresses have created a production level bottleneck whose solution possibly lies in the use of crop wild relatives and other genetic traits cultivated by tailoring novel germplasm. Presenting options for widening the genetic base of chickpea cultivars by introgression of diverse genes available in distantly related wild Cicer taxa, thus expanding the genetic base and maximize genetic gains from the selection, it is necessary to accumulate other complimentary alleles from CWRs. This review will focus on present status of gene pool and species distribution, germplasm conservation, characterization and evaluation, problems associated with crop production, sources of target traits available in wild species, status of trait introgression in synthesizing new gene pool of chickpea along with progress made in chickpea genomics. An edited book with contributions from leading scientists, this information will guide and inform chickpea breeders, PGR researchers and crop biologists across the world. Presents both conventional and emerging techniques Provides insights into gene pyramiding as cytogenic manipulations Includes case studies highlighting the impact of improving chickpea production

Gene Flow Between Crops and Their Wild Relatives by Meike S. Andersson,M. Carmen de Vicente Pdf

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.

Alien Gene Transfer in Crop Plants, Volume 1 by Aditya Pratap,Jitendra Kumar Pdf

Genetic engineering and biotechnology along with conventional breeding have played an important role in developing superior cultivars by transferring economically important traits from distant, wild and even unrelated species to the cultivated varieties which otherwise could not have been possible with conventional breeding. There is a vast amount of literature pertaining to the genetic improvement of crops over last few decades. However, the wonderful results achieved by crop scientists in food legumes’ research and development over the years are scattered in different journals of the World. The two volumes in the series ‘Alien Gene Transfer in Crop Plants’ address this issue and offer a comprehensive reference on the developments made in major food crops of the world. These volumes aim at bringing the contributions from globally renowned scientists at one platform in a reader-friendly manner. The 1st volume entitled, ‘Alien Gene Transfer in Crop Plants: Innovations, Methods and Risk Assessment” will deal exclusively with the process and methodology. The contents of this volume have been designed to appraise the readers with all the theoretical and practical aspects of wide hybridization and gene transfer like processes and methods of gene transfer, role of biotechnology with special reference to embryo rescue, genetic transformation, protoplast fusion and molecular marker technology, problems such as cross incompatibility and barriers to distant hybridization and solutions to overcome them. Since wild and weedy relatives of crop plants may have negative traits associated with them, there are always possibilities of linkage drag while transferring alien alleles. Therefore, problems and limitations of alien gene transfer from these species will also be discussed in this series. Further, the associated risks with this and assessment of risks will also be given due weightage.

Biotic Diversity and Germplasm Preservation, Global Imperatives by Lloyd Knutson,Allan K. Stoner Pdf

Topics for the Beltsville Symposia are selected to highlight specific areas of research and science policy that are of concern to scientists in the Beltsville Area as well as to the general scientific community. Each sympo sium in the series is structured to provide a realistic appraisal of current findings, research progress, and relevant policy issues within the constraints established by the organizing committee. Thus, the presentations and dis cussions that have marked these symposia have had a strong appeal to the broad community of scientists. Knowledge of the diversity of living organisms is still quite limited. Since the time of Linnaeus, about 1.7 million species have been described. The actual number has been estimated between 5-50 million. Many species, land races, and strains are vanishing. Clearly, the world's scientific institutions are inadequately equipped to attain sufficient knowledge of a significant fraction of the diverse living forms. Also, efforts in the collection and preservation of germplasm of plants and animals urgently need to be strengthened. These mattes are critically important to future generations. This symposium addresses vital concerns of biotic diversity and germ plasm preservation from diverse perspectives. Many of the parts provide concrete recommendations for action, and they call attention to areas of research that must be pursued with intensity.
