The first revolution in wheat breeding occurred through germplasm exchange. A second revolution will exchange information related to germplasm, which not only adds value to germplasm, but also strengthens bonds between institutions and between scientists. We are on the threshold of dramatic advances, limited only by our imaginations in using them. Positive dynamic feedback between genetics, both conventional and molecular, and environmental information will provide unprecedented insights into crop adaptation. In the past, information generated by different sources, e.g. national trials, international trials, laboratories, and germplasm banks, could not be integrated around the germplasm to which it pertained. For this reason, the CIMMYT Wheat Program resolved to develop a strategy that relies on unique identification of germplasm and on the features of relational databases to manage global data pertaining to wheat. Implementation is in three phases: The Wheat Pedigree Management System (WPMS) has been completed and uniquely identifies germplasm by cross identification (CID) and selection identification (SID) numbers. The Wheat Germplasm Bank System (WGBS). The Wheat Data Management System (WDMS), which will complement WGBS and consider three types of data categories-Genetic (C), Genotype x Environment (GE), and Environmental (E) and the interrelations among them. We will link to Geographic Information Systems through E data and to genetic mapping initiatives through G data
