| Abstract: | Abstract Root architecture is great importance to P uptake efficiency of leguminous crops. Some parametersof root architecture, such as root biomass, root length and root surface area, were found to be closely relatedto P uptake efficiency of common bean, soybean and Stylosanthes spp. In this paper, the concept and re-search methodology of root architecture were briefly reviewed in relation to the P uptake efficiency of someleguminous crops. It was suggested that integrated models of root architecture should be developed to pro-vide comprehensive yet realistic indices for effective genetic improvement of P efficlency of the crops.
