The Crop Science Society of America (CSSA), since its inception in 1955, and before that the American Society of Agronomy (ASA), recognized the importance of free exchange of information and free distribution of germplasm for the improvement of agronomic rops. This recognition is manifest in the form of publishing registrations in Crop Science to document he development of unique germplasm and to allow for its free distribution. Cultivars have been registered since 1926 (up to 1955 by ASA and thereafter by CSSA), parental lines and germplasm since 1955, and genetic stocks since 1988. The Crop Registration Committee (C852) and CSSA have recognized the role and importance of molecular genetics in crop improvement by creating a fifth crop registration category mapping populations at the 1999 Annual Meetings at Salt Lake City, UT, 31 October-4 November. Mapping populations are essential tools for molecular genetic analysis and gene mapping. The new category is warranted because of the uniqueness of mapping populations and the expectation for their expanded use. There were two main considerations in developing guidelines for the registration of mapping populations. First, the potentially large number of individuals within a population were considered too unwieldy for automatic entry in the National Plant Germplasm System (NPGS), as is now the case for other registrations. And second, the free availability of material should be maintained according to longstanding CSSA policy. In consideration of these factors, the following guidelines for registering mapping populations in Crop Science were developed.
