Food Security in Nutrient-Stressed Environments: Exploiting Plants' Genetic Capabilities, Summary and Recommendations of an International Workshop 27-30 Sep 1999J JAdu-GyamfiauthorAttended by 50 international participants, this workshop marked the culmination of Phase III of a 15-year Special Project at the International Crops Research Institute for the Semi-Arid Tropics (ICRISAT) funded by the Government of Japan Entitled "Sustainable cultivation of upland crops in the semi-arid tropics", the Project was executed in collaboration between ICRISAT and Japan International Research Center for Agricultural Sciences (JIRCAS). The workshop objectives were to: Explore the scope for genetic manipulation of the ability of crop plants to access and use nutrients, prioritize candidate mechanisms of enhancing nutrient uptake and use in terms of their suitability for genetic manipulation, examine appropriate methodologies for genetic enhancement of crop plants' ability to absorb nutrients and use them efficiently, and suggest how genetic options can best be combined with management options to improve nutrient uptake and use. Over 30 papers were presented in sessions on: sustainability of breeding for low-nutrient environments, candidate mechanisms, methodologies, and combining genetic improvement with natural resource management. Extended abstracts of all papers are included, together with an introductory review that includes colored photographs of Project Highlights. Session interpretive summaries, and recommendations for future research needs, priorities and strategies are provided.Agriculture-Farming, Production, Technology, Economics1999International Crops Research Institute for the Semi-Arid TropicsMonograph
