Synopsis

During the last thirty years, most increases in agricultural production were achieved through high input agrieulture in areas with fertile soils and sufficient water. Intensive methods of production with high levels of nitrogen fertilizer and pesticides were often accompanied by environmental degradation and in some instances by pollution of the food supply. However, rapid population growth has also led to increasing use of marginal lands, where adverse soil and climatic eonditions are serious constraints to food production. These areas are even more sensitive to ecological destabilization. Environmentally sound systems of food production and land use are essential for meeting the food security needs of developing countries. To do this, greater genetic variability is needed within the best crop genotypes available for the areas in need coupled with better management praetices and crop rotations. These requirements can only be realized if suitable crop varieties are bred. These should be varieties with a much shorter growing period, suitable for rotation, increased tolerance or resistance to diseases and pests as weil as to drought and salinity and other adverse soil and climatic conditions.

Présentation de l'éditeur

This publication contains the results of an Fao/Iaea Co-ordinated Research Project (Crp) on Radiation Induced Mutations and Other Advanced Technologies for the Production of Crop Mutants Suitable for Environmentally Sustainable Agriculture. Induced mutation techniques and other biotechnological approaches are major tools for creating variability and selection of stress-resistant or tolerant genotypes. Additionally, scientists have become intensely interested in mutations as a means to widen and deepen our understanding of genome structure and gene function.
