Abstract One of CIMMYT's primary functions is to produce germplasm for use by cooperating national crop improvement programs. In the development of wheat germplasm, emphasis is given to producing advanced materials that can be readily integrated into national wheat-breeding programs. Early generation segregating materials are also made available to cooperators. Each year, CIMMYT makes thousands of bread wheat crosses and generates hundreds of advanced lines. These materials are distributed annually to national programs by way of our international nursery system; nearly 50 nurseries consisting of advanced yield trials, screening nurseries and F2 segregating populations are distributed annually to over 200 cooperators around the world. National programs are free to use the germplasm in these nurseries in any way that best suits their needs. Options range from crossing with local varieties to placing entries directly into multiplication for eventual release as varieties. The reader should note that CIMMYT does not release or name varieties; that is the right and responsibility of cooperating national programs, and each national program has its own system for naming released cultivars. CIMMYT does name its advanced bread wheat breeding lines, and our system for differentiating among these lines currently utilizes the names of land birds only. At one time, however, the names of mountains, lakes, rivers, islands and certain phonetic combinations were used; some of these earlier names remain in use today. The CIMMYT/ICARDA program continues to use phonetic combinations or combinations of parental names. This revised bulletin contains a compilation of all semidwarf bread wheat cultivars and advanced lines produced by CIMMYT and by the Mexican National Institute of Agricultural Research (INIFAP); it also contains the names and pedigrees of cultivars with CIMMYT parentage that have been released since 1962 by cooperating national programs. Our purpose in publishing this bulletin is to facilitate the exchange of more exact information among wheat researchers working with these materials, and to assist them in their note taking and record-keeping activities.
