Grain yield, quality and minerals in field-grown durum wheat under Mediterranean conditions [Dataset]
Year: 2026
Type: dataset
Abstract: This dataset contains phenotypic measurements from 22 durum wheat cultivars evaluated across multiple environments in the Spanish Iberian Plateau over three growing seasons. Trials were conducted under contrasting environmental and management conditions, including different water regimes, sowing dates, nitrogen supplies, and years. Agronomic, technological quality, and grain mineral concentration traits were assessed, including grain yield, protein content, and concentrations of C, N, K, P, S, Mg, Ca, Fe, Mn, Zn, and Cu. The dataset was generated to investigate the relative contributions of genotype, environment, and genotype-by-environment interactions to variation in grain mineral composition and associated traits. It also supports the evaluation of relationships among grain yield, quality, and nutrient concentration, as well as the identification of superior cultivars through multi-trait performance and stability analyses. These data provide a valuable resource for studies on durum wheat breeding, biofortification, genotype-by-environment interactions, and the development of predictive and machine-learning models for crop improvement.
