This book was released on 2012-12-06 with total page 186 pages. Available in PDF, EPUB and Kindle. Book excerpt: It has become apparent, during discussions with students and colleagues in forest genetics, that a universal concern is the achievement of diverse goals of forestry from fiber production in industrial as well as farm forests to conserving forest ecosystems. Although we generally have several breeding methods available and several species to breed, we seek to satisfy multiple-use goals on diverse sites by management techniques that at best can only partially control edaphic environmental variation. The dominant approach, which was agriculturally motivated, has involved inten sive effort with complicated breeding plans on single species for uniform adaptability and single-product plantations. However, this is obviously neither the only, nor necessarily the best, solution for the genetic management of tree species, and thus our intent in this volume is to develop ways to achieve multiple objectives in tree breeding. We include an array of breeding plans from simple iterated designs to sets of multiple populations capable of using gene actions for different traits in different environments for uncertain futures. The presentation is organized around the development of breeding from single-to multiple-option plans, from single to multiple traits, from single to mUltiple environ ments, and from single to multiple populations. However, it is not a complete "How To" book, and includes neither exercises nor instructions on data handling. It also does not include discussion of all modes of reproduction and inheritance encountered in plants.
Download or read book Tree Breeding and Improvement Theory and Technology written by K.T. Parthiban and published by Scientific Publishers. This book was released on 2020-05-19 with total page 391 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tree Breeding and lmprovement is gaining significant attention and attraction across the country as a scientific tool to enhance the productivity and wood quality besides facilitating conservation of Forest Genetic Resources. The science of Tree Breeding is comparatively young but extended greater scope in the recent past in operational plantation development programme. The Tree Breeding and lmprovement has been incorporated as a subject in Under Graduate as well as Post graduate degree programme in Forestry offered at various State Agricultural Universities of the country. The existing text books on Tree Breeding are very limited and the practical aspects of tree breeding have not been evidenced in most books. The students and the tree breeding scientists require a comprehensive text book incorporating all theoretical and practical aspects of tree breeding. Accordingly the current book entitled “TREE BREEDING AND IMPROVEMENT - THEORY AND TECHNlQUES” has been designed with 18 chapters. The basic and fundamental aspects of tree breeding have been presented in chapter 1. The chapters 2 and 3 elaborate the Center’s of origin and pollination mechanism of trees. The theoretical and practical aspects of tree breeding methods, hybrid development, genetic tests and their biometric analysis have been presented with suitable field level examples from chapter 4 to 9. Incorporation of Seed orchard, clonal forestry, Exotic Forestry and Forest Biotechnology with -the-state-of-art- recent development will find greater utility by the students and researchers. Above all, the chapters on Varietal Developmental Process, Variety Registration and Organizations involved in tree breeding will have profound utility. ln a holistic perspective, the information furnished in the book will act as a great piece of information to the graduating scholars to understand theoretical and practical aspects of tree breeding towards satisfying their academic needs besides applying them in tree breeding research. For the scientists and teaching faculties, the book will act as a ready reckoner not only for reference but also to apply them in all field level applications.

Available in PDF, EPUB and Kindle. Book excerpt: The recent development of ideas on biodiversity conservation was already being considered almost three-quarters of a century ago for crop plants and the wild species related to them, by the Russian geneticist N.!. Vavilov. He was undoubtedly the first scientist to understand the impor tance for humankind of conserving for utilization the genetic diversity of our ancient crop plants and their wild relatives from their centres of diversity. His collections showed various traits of adaptation to environ mental extremes and biotypes of crop diseases and pests which were unknown to most plant breeders in the first quarter of the twentieth cen tury. Later, in the 1940s-1960s scientists began to realize that the pool of genetic diversity known to Vavilov and his colleagues was beginning to disappear. Through the replacement of the old, primitive and highly diverse land races by uniform modem varieties created by plant breed ers, the crop gene pool was being eroded. The genetic diversity of wild species was equally being threatened by human activities: over-exploita tion, habitat destruction or fragmentation, competition resulting from the introduction of alien species or varieties, changes and intensification of land use, environmental pollution and possible climate change.
Download or read book Shifting Cultivation and Environmental Change written by Malcolm F. Cairns and published by Routledge. This book was released on 2015-01-09 with total page 1057 pages. Available in PDF, EPUB and Kindle. Book excerpt: Shifting cultivation is one of the oldest forms of subsistence agriculture and is still practised by millions of poor people in the tropics. Typically it involves clearing land (often forest) for the growing of crops for a few years, and then moving on to new sites, leaving the earlier ground fallow to regain its soil fertility. This book brings together the best of science and farmer experimentation, vividly illustrating the enormous diversity of shifting cultivation systems as well as the power of human ingenuity. Some critics have tended to disparage shifting cultivation (sometimes called 'swidden cultivation' or 'slash-and-burn agriculture') as unsustainable due to its supposed role in deforestation and land degradation. However, the book shows that such indigenous practices, as they have evolved over time, can be highly adaptive to land and ecology. In contrast, 'scientific' agricultural solutions imposed from outside can be far more damaging to the environment and local communities. The book focuses on successful agricultural strategies of upland farmers, particularly in south and south-east Asia, and presents over 50 contributions by scholars from around the world and from various disciplines, including agricultural economics, ecology and anthropology. It is a sequel to the much praised "Voices from the Forest: Integrating Indigenous Knowledge into Sustainable Upland Farming" (RFF Press, 2007), but all chapters are completely new and there is a greater emphasis on the contemporary challenges of climate change and biodiversity conservation.
