Interpretive Summary: The Crop Registration Committee (C852) and the Crop Science Society of America (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, Utah, October 31- November 4. 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 is also the potential for a large number of populations to be developed for a given crop species. 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, guidelines for registering mapping populations in the Crop Science Journal were developed.
