The international wheat information system (IWIS) The International Wheat Information System (IWIS) is an information management aid established by the International Maize and Wheat Improvement Centre (CIMMYT) for wheat scientists. It handles and integrates all kinds of information on bread wheat, durum wheat and triticale easing access to the vaste and intricate body of data on these crops. By providing plant collectors, curators, and breeders with a common language to uniquely identify individual wheats and triticales, IWIS seamlessly joins the conservation, utilization and exchange of genetic material. A wealth of data on wheat genetic resources has accumulated in gene banks, research centres and laboratories scattered around the world. Data, gathered from trials which have been taking place since the 1950s, contain invaluable details on the specific traits, places of origin and performance of thousands of wheat varieties. The data are incorporated into IWIS through two major components; the Wheat Pedigree Management System, and the Wheat Data Management System. The Wheat Pedigree Management System assigns and maintains unique wheat identifiers and genealogies enabling scientists to pinpoint a particular wheat, despite its numerous names, and to trace its family tree. The Wheat Data Management System manages performance information and data on the known genes. IWIS is also linked to the USDA-sponsored Grain-Genes initiative on molecular mapping, providing access to further information. IWIS: provides quick, user-friendly options for managing and searching wheat data; gathers information from genebanks, laboratories and field tests and puts it to work in plant improvement; makes it possible to estimate the degree of relatedness among wheats through a unique identifier that traces the ancestry of individual wheats; identifies materials that have not been used to improve wheat and could provide new sources of desirable traits; allows breeders to increase genetic diversity by selecting materials of divergent parentage for crosses, thereby reducing wheat's vulnerability to diseases and climatic changes; updates family trees automatically as additional ancestry is discovered; and avoids the unnecessary repetition of expensive evaluations. By collating information from different research programmes in related fields and also relevant data from other disciplines, IWIS can increase the speed with which information can be located and accessed. Available annually on CD-ROM, IWIS will help crop scientists in NARS and other research institutions, who will be able to locate, access and obtain the genetic resources they need for their research. IWIS has also served as a model for a collaborative project between CIMMYT and other CGIAR centres, to develop the International Crop Information System (ICIS) which will provide similar data management facilities for a wide range of crops.
