Conteúdo: 	A core collection has been described as a collection which contains, with a minimum of repetiveness, the genetic diversity of a crop species and its wild relatives. Such a collection is not intended to replace existing genebank collections but to include the total range of genetic variation of a crop in a relatively small and manageable set of germplasm accessions. It has been argued that the development of core collections will improve management and utilization of crop plant genetic resources and provide a guide to future germplasm collecting activities. Howerver, concern has also been expressed that the information needed to develop core collections is not available for most crop species and that accessions with desirable characteres will be omitted from the core colletion. Core collections of okra, wild Glycine spp. and winter wheat have already been described. An IBPGR survey has shown that projects to develop core collections of a number of cereal, legume, forage, vegetable and fruits crops are also in progress. These projects should provide much needed information on the different approaches being investigated, the data needed to develop such collecttions, the most effective sampling methods and the extent to which the collections have captured the required genetic diversity. The development of core collections is likely to involve a number of features of direct importance to those concerned with developing new concepts for collaborative genetic resourses management. These include collaboration between.
