Plants are the basis of life on earth. We cannot overemphasize their importance. The value of plant genome initiatives is self-evident. The need is to identify priorities for action. The angiosperm genome is highly variable, but the extent of this variability is unknown. Uncertainties remain about the number of genes and the number of species living. Many plants will become extinct before they are discovered. We risk losing both genes and vital information about plant uses. There are also major gaps in our karyotypic knowledge. No chromosome count exists for 70% of angiosperm species. DNA C values are known for only approximately 1% of angiosperms, a sample unrepresentative of the global flora. Researchers reported new relationships between genome size and characters of major interest for plant breeding and the environment and the need for more data. In 1997, a Royal Botanic Gardens Kew workshop identified gaps and planned international collaboration to fill them. An electronic version of the Angiosperm DNA C value database also was published. Another initiative, which will make a very significant contribution to the conservation of plant genetic diversity on a global scale is Kew's Millennium Seed Bank, partly funded by the U.K. Millennium Commission, celebrating the year 2000. Costing up to 80 million pounds (1 million pounds = $1.62), its main aims are to collect and conserve the seed of almost all of the U.K. spermatophyte flora by the year 2000, to collect and conserve a further 10% of the world spermatophyte flora principally from the drylands by 2009, and to provide a world class building as the focus of this activity by 2000

The 20th century began with a rapid ramping up of national investments in and institutions engaged with research for food and agriculture. As the 21st century unfolds, the global science and agricultural development landscapes are changing in substantive ways, with important implications for the funding, conduct and institutional arrangements affecting research for food and agriculture. Wheat improvement research is part of this broader agricultural innovation landscape. While there is a general consensus that the present and prospective future of the agricultural sciences bears little resemblance to the situations that prevailed in the formative years of today's food and agricultural research policies and institutions, many of these changes are poorly understood or only beginning to play out. This paper reports on selected new and emerging empirical evidence to calibrate the strategic private and public choices being made regarding wheat research in particular and food and agricultural R and D more generally.

In all but the poorest countries of South Asia and Africa, the supply and quality of food will rise to meet the demand. Biotechnology, accelerated by genomics, will create wealth for both producers and consumers by reducing the cost and increasing the quality of food. Famine and malnutrition in the poorest countries may be alleviated by applying genomics or other tools of biotechnology to improving subsistence crops. The role of the public sector and the impact of patent law both could be great, but government policies on these issues are still unclear
