In the foot hill dryland of Ñuble (Lal. 37°01' S., Long. 72°02' W.) during the 1981-1985 period, fifteen trials were set up. The aim was to make a preliminary selection of wheat genotypes based in their performance related to the use of phosphorus. Therefore an Andepts Soil low in P (< 8 mg/kg), was selected. Differences in rusticity and efficiency in the use of phosphorus were observed between grain yield of the wheat genotypes and the rates of phosphorus applied.
