The goal of the study was to analyze the mineral composition of 35 Argentinean wheat cultivars over two years. The researchers found that the mineral levels in the grains varied widely, with some differences between cultivars remaining consistent over time. They also discovered that certain cultivars had distinct elemental profiles that stayed consistent across the years. Interestingly, there were negative correlations between nutrient levels and yield, suggesting a trade-off between grain quality and quantity. This variation in mineral composition could be useful for breeding programs aiming to enhance the nutritional quality of wheat.
