Conteúdo: 	The descripition of accessions and the recording of the information in databases are one aspect of genetic resources work which has progressed slowly. The larger number of samples now conserved in gene banks makes their comprehensive description and evaluation a formidable task. Over the past decade the IBPGR alone has organised the collection of more than 130,000 primitive accessions of diverse crops which are, in the main, population samples. Other genetic resources programmes have developed in scores of countries so that curators have been faced with an unprecedented management problem. It is conservatively estimated that the number of accessions in germplasm collections now totals several million due to extensive duplication.
