Hardcover. Zustand: New. To increase both sustainability and productivity in agriculture, crop science, from pre-breeding to production management, needs to make better use of genetic diversity. For instance, adapted and exotic genetic resources can greatly contribute to generate varieties with enhanced adaptation to different climatic conditions and with improved plasticity in response to stressful factors. These features are central to reducing vulnerability to stress and supporting more diversified and sustainable agro-ecological systems. The methods of biotechnology now permit a greater understanding of both species and genetic diversity in plants, the mechanisms by which that variation is generated in nature, and the significance of that variation in the adaptation of plants to their environment. They allow the development of rapid methods for screening germplasm for specific characters and promote more effective conservation strategies by defining the extent of genetic diversity. Tissue culture-based techniques are available for conserving germplasm that cannot be maintained by more traditional methods. The impact of new innovations is wide-ranging and includes the possibility to improve our understanding and exploitation of plant genetic resources for food and agriculture (PGRFA). These new technologies are expected to transform the study of PGRFA into a more technologically intensive, information-rich science, in which the integration and interpretation of different kinds of data will be central to fully unlock the potential of genetic diversity for agriculture. We hope and trust that the information in this book will be used as the basis for policy and technical decisions to strengthen national efforts to conserve and utilize the treasures incorporated in the Indian plant genetic resources to address the urgent problems faced by agriculturists.…

Hardcover. Zustand: New. 1st Edition. The modern plant breeding methods have their bases in the genetic and cytogenetic principles. The science of genetic began with rediscovery of Gregor J. Mendel's paper in 1900, which was originally published in 1866. Mendel's laws of inheritance provided the foundation for the vast knowledge that has, since then, accumulated in genetics. Numerous workers who determined the various modes of inheritance have contributed to the development and understanding of plant breeding. The totipotancy of plant somatic and gametic cells allows regeneration of complete plants from single cells. This, coupled with development of recombinant DNA technology, has enabled the transfer of desirable genes from any organism into plants. Crop varieties developed in this manner are already in cultivation in several countries, primarily U.S.A. and world acreage under them is increasing at a very rapid rate. These exciting developments are expected to become increasingly important with time. The main objectives of the book may be summarised as follows: Higher Yields, mproved Quality, Disease and Insect Resistance, Change in Maturity Duration, Agronomic Characteristics, Oilseeds : Major breeding procedures, Fruit Crops: Major Breeding Procedures, Seed Multiplication and Release of a Variety and soon.…

Hardcover. Zustand: New. 1st Edition. Seed Science and Technology is one that gives a good overview of the whole area of seed development, dormancy and germination, including hormonal regulation of seed germination as well as seed quality aspects such as testing, seed vigor, seed-borne pathogens, and seed quality. This book goes one step further, as it has information related to seed predation and natural defense mechanisms of seeds, information on the eco-physiological basis of weed seed longevity in soil, seeds and soil seed banks, as well as hybrid seed production and plant germplasm conservation. The reader has an opportunity to get information in almost any area related to seeds. (jacket). …
