摘要
Intra-specific variations of phosphorus-utilization efficiency (PUE) hold great promise in rationalizing the application of cost-intensive phosphatic fertilizers in resource-poor situations, and to extend the useful life of the phosphate reserves in the world. In developed countries, efficient P-using crops may find significance in protecting the environment by reducing pollution of surface and ground water resources. This paper briefly reviews some of the work done so far on genotypic variations of Phosphorus (P)-nutrition of craps. Several physiological mechanisms responsible for such variations have been recognized. Various screening techniques to select P-efficient genotypes are also discussed. In addition, a brief historical account is also given on plant genetic approach to tackle soil problems.
