Plant genetic resource management: The next investments in quantitative and qualitative genetics

Abstract

Substantial investments are being made in molecular genetic technology as a means to support plant breeding and improved crop and forestry productivity. We suggest that although these investments will bring some benefits, it is critical that this technology not replace or even limit the expansion of more traditional breeding activities. Biotechnology firms create a situation where investors require almost immediate returns. Globally, this may be at the expense of longer-term returns that will arise from investments in different types of pre-breeding, breeding, testing and selection efforts that are needed in many varieties or populations of lesser-developed species. National and international agencies, responsible for conserving and breeding crop and forest tree genetic resources, need to think about and undertake programs that consider the dynamics of evolutionary change in crops as the main focus, supported by molecular genetics. A better balance between investments in privately funded single-gene technologies, and the maintenance and development of multiple-gene sets in many more species than we consider today, will be of much more value to society in the long run.
