Breeding for Biotic Stress Tolerance in Plants

摘要: Modern agriculture is concerned with the production of crops used primarily for human and animal food, but in so doing there often need (in some cases by law) to protect environment. In crop also lower costs, especially reduce use expensive pesticides fertilizers. It an important aim, which not always fulfilled apply fertilizers only when needed, order this strategy succeed, a better understanding biotic stress associated influences from plant breeding achievements required. Therefore impact injury plants yield economic importance directly related other biological environmental questions. For example, decision made over control forms part Integrated Pest Management (IPM). chapter, we deal latest results conclusions losses pathology, entomology weed science, successful application approaches limiting such reductions. We intend cover all classes stressors, methods commonly diversity organisms involved. will focus on current knowledge fitness loss agricultural ecosystems, improved that can tolerate these factors. first chapter crops, limitations, conventional molecular breeding, where DNA-based markers have been advantages traditional phenotype trait selection. Molecular be tag resistance genes, they serve improvement efficiency selection called marker assisted (MAS). The potential benefits MAS are discussed, overcome problems faced classical phenotypic screening programs. second discuss within context each class involved losses, attempt evaluate available damage. Abiotic (dealt elsewhere book) mentioned time certainly make strong argument integrated approach two types stresses whenever possible.
