The complex of acidity in tropical soils includes low pH, toxic levels of Al, low availability associated with high adsorption of phosphorus (P), and a generalized low level of plant nutrients. This soil acidity complex often creates a chemical barrier to root growth and development, decreasing root contact with soil nutrients and water, resulting in even greater water and nutrient stress. The objective of this research was to identify genetic resources of sorghum both efficient and inefficient in P acquisition and responsive and non-responsive to applied P. Thirty six sorghum lines, 12 traditional lines representing both tolerance and susceptibility to Al toxicity and 24 lines derived from crosses between elite B-lines and a source of tolerance to Al toxicity, SC 283 (IS7173C), were evaluated for P acquisition efficiency on a Dark Red Dystrophic Latosolo under Cerrado vegetation at the National Maize and Sorghum Research Centre of Embrapa at Sete Lagoas, Minas Gerais, Brazil. The soil was limed to raise the pH to a range between 5.5 and 6.0. Two levels of soil phosphorus were used, 50% (5 ppm) and 100% (10 ppm) critical level with no additional P added in the second year. The 36 entries were classified into four groups; efficient and responsive to P (ER), non-efficient and responsive to P (NR), efficient and not responsive to P (EN), and non-efficient and not responsive to P (NN), according to their field performance for grain yield. Genetic variability for both P use efficiency and P responsiveness was identified within the set of 36 sorghum line representing both tolerance and susceptibility to Al toxicity.
