MANAGING GLOBAL GENETIC RESOURCES: The U.S. National Plant Germplasm System The National Academy of Sciences is a private, nonprofit, self-perpetuating society of distinguished scholars engaged in scientific and engineering research, dedicated to the furtherance of science and technology and to their use for the general welfare. Upon the authority of the charter granted to it by the Congress in 1863, the Academy has a mandate that requires it to advise the federal government on scientific and technical matters. Dr. Frank Press is president of the National Academy of Sciences. The National Academy of Engineering was established in 1964, under the charter of the National Academy of Sciences, as a parallel organization of outstanding engineers. It is autonomous in its administration and in the selection of its members, sharing with the National Academy of Sciences the responsibility for advising the federal government. The National Academy of Engineering also sponsors engineering programs aimed at meeting national needs, encourages education and research, and recognizes the superior achievements of engineers. Dr. Robert M. White is president of the National Academy of Engineering. The Institute of Medicine was established in 1970 by the National Academy of Sciences to secure the services of eminent members of appropriate professions in the examination of policy matters pertaining to the health of the public. The Institute acts under the responsibility given to the National Academy of Sciences by its congressional charter to be an adviser to the federal government and, upon its own initiative, to identify issues of medical care, research, and education. Dr. Samuel O. Thier is president of the Institute of Medicine. The National Research Council was organized by the National Academy of Sciences in 1916 to associate the broad community of science and technology with the Academy's purposes of furthering knowledge and advising the federal government. Functioning in accordance with general policies determined by the Academy, the Council has become the principal operating agency of both the National Academy of Sciences and the National Academy of Engineering in providing services to the government, the public, and the scientific and engineering communities. The Council is administered jointly by both Academies and the Institute of Medicine. Dr. Frank Press and Dr. Robert M. White are chairman and vice-chairman, respectively, of the National Research Council.

MANAGING GLOBAL GENETIC RESOURCES: The U.S. National Plant Germplasm System Preface The work of sustaining a productive agriculture by developing new crops and improving existing ones is inextricably linked to the need for plant germplasm—the broad array of materials, from seeds to large trees, that are maintained and preserved because of the genetic traits they may contain. Germplasm manipulation led to the production of the high-yielding varieties of rice, wheat, and maize that now play a key role in world food production. The conservation and exchange of germplasm have become important concerns for many nations and international institutions. This report examines the management of plant germplasm in the United States and the activities of the National Plant Germplasm System (NPGS). It may also serve as a springboard for discussions about the establishment of a U.S. program that encompasses a broader array of genetic resources. The NPGS holds a wide array of germplasm collections and is the world 's most active distributor of germplasm samples to other nations. The scientific, technical, and support staff at many of its facilities are dedicated to preserving these important resources for future generations. The committee recognizes the past important contributions made by many dedicated individuals who have contributed to the achievements of the NPGS. As the size and number of NPGS collections have grown over the years, the task of managing them at a number of sites located throughout the United States has also increased. As a result, the national system has become a loose association of sites and organizations that, at times, has a diversity of goals and lacks coordinated leadership. The NPGS

MANAGING GLOBAL GENETIC RESOURCES: The U.S. National Plant Germplasm System will continue to grow and it must continue to respond to emerging needs. It must now become a distinct, centrally managed, and nationally coordinated unit of the U.S. Department of Agriculture. This report is directed toward accomplishing that end. The Committee on Managing Global Genetic Resources, established by the National Research Council in November 1986, is concerned with the world's genetic resources that have an identified economic value. These resources are important to agriculture, forestry, fisheries, and industry. The committee has been assisted by two subcommittees and several work groups that gathered information or prepared specific reports. One of the work groups, chaired by Calvin O. Qualset, examined the U.S. National Plant Germplasm System and drafted this report. It is one of five committee reports to be published in a series entitled, Managing Global Genetic Resources. Other reports prepared by the committee, its subcommittees, and work groups address issues related to the global management of forest trees, livestock, fish and shellfish, and crop plants. The examination of crop plants will be included in the committee's main report, which will address the legal, political, economic, and social issues surrounding global genetic resources management as they relate to agricultural imperatives. In addition, a work group was appointed to provide information that would aid in planning and designing a new storage facility for the National Seed Storage Laboratory. The committee released a letter report, Expansion of the U.S. National Seed Storage Laboratory: Program and Design Consideration, in April 1988. Copies of this report are available from the Board on Agriculture. The charge to the NPGS Work Group was to assess the structure and operation of the components of the national system; to determine its adequacy in applying technology as well as anticipating and meeting the present and foreseeable needs of U.S. agriculture; and to examine the policies guiding its interaction in the international conservation and use of plant genetic resources. Within the context of the committee 's work, examination of this system provides a valuable case study for similar programs in other countries. More specifically, the work group was asked to do the following: Assess the extent to which the organization, administration, and operation of the present system meet the needs of exploration, collection, conservation, and use of agricultural plant germplasm. Consider to what extent present arrangements encourage or constrain cohesiveness and coordination, and promote wide participation within the system.

MANAGING GLOBAL GENETIC RESOURCES: The U.S. National Plant Germplasm System Determine the appropriate roles for the various elements of the system at national and state levels, as well as the nature of the interaction between the public and private sectors in germplasm conservation. In the context of meeting the needs of U.S. agriculture, define the possible interactions of the NPGS with other national and international programs, and examine the potentials for international cooperation for collection, conservation, or distribution and the adequacy of U.S. policy in this regard. Define priority needs of the national system, in terms of funding, existing technologies, facilities, personnel, and research. Define and assess the nature of linkages between base collections, working collections, and in situ collections as these relate to the work of the NPGS and plant breeders. The report begins by outlining the challenges of managing plant germplasm, describing the components of a national system, and reviewing the origins of germplasm management in the United States and the development of the NPGS. Chapter 2 details the sites, collections, laboratories, and offices that comprise the national system. Chapter 3 describes the administrative components of the NPGS and how the system obtains and acts upon advice. The committee's recommendations make up the last chapter. The committee offers these to aid the NPGS in continuing and enhancing its impressive record of service to U.S. and global agriculture. Appreciation of the importance of plant germplasm and its impact on the development of modern agriculture can easily be obscured amid the details of multiple administrative relationships and site descriptions. An understanding of how a small, weedy plant growing in a distant land can be important to this process is often lost. For this reason the report contains summaries of six individual germplasm samples and the diverse ways in which they came to be recognized and used. PETER R.
