Plant Quarantine and the International Transfer of Germplasm

摘要

The report reviews the history of quarantine services, discusses principles for successful quarantine operations, identifies major constraints to the exchange of plant materials due to quarantine restrictions and procedures, and explores some of the difficulties faced by quarantine services, plant breeders, and genebank curators in attempting to detect diseases or pests and clean up seeds and vegetative materials. Disease and pest screening techniques are examined, with an emphasis on emerging biotechnologies. The importance of intermediate quarantine for tropical cash crops is underscored. Ways to strengthen quarantine services worldwide are analyzed for crop improvement programs. (Copyright (c) 1988, The World Bank.)
