| Sumario: | Corn is one of the most important worldwide food crops. Most of the corn cultivated in Misiones province corresponds to landraces adapted to a great variety of ecological conditions.Information about the chemical composition of these materials is scarce. In order to evaluate the nutritional potential of local germplasm, 16 landraces and 4 controls were studied. The protein, oil, starch and amylose concentration and the fatty acid profile were determined by methods validated by the Association of Official Analytical Chemists. The results obtained showed values of 9.9 to 13.4% of protein, 3.81% to 6.11% of oil, 66.6% to 74.8% of starch, and 20% to 24.6% of amylose. Considerable variation was observed in the fatty acid composition, with average of 13.4% palmitic, 2.01% stearic, 35.6% oleic, 48.2% linoleic and 0.79% linolenic.Native populations showed a differential capacity to provide advances for the quality traits evaluated. Detection of materials with outstanding characteristics shows the genetic potential present in the local germplasm and provides valuable information for genetic improvement and acknowledgment of the value of native resources. |
