CIMMYT's 2000-2002+ Medium Term Plan (MTP) reflects several shifts in priorities and strategy as we prepare to enter the new millennium. The driving force behind our planning, however, remains the indisputable fact that maize and wheat will clearly dominate global food security in the next century. The fundamental elements of our MTP continue to serve as an effective guide for planning and implementing needed changes in the Center's research agenda. We begin this document with an updated assessment of the current and future importance of maize and wheat, followed by highlights of our research and an overview of financial circumstances in 1998/1999. The accompanying financial tables appear on pages 16-35. Our project portfolio, including updated milestones for achieving objectives, appears in the annex on page 36. This latest version of our project portfolio begins to introduce the CGlAR logframe vocabulary that will become our standard for future MTPs.76 pages
