  Essential minerals are considered as key determinants of optimum health and nutritive quality of common bean seed. This study aimed to identify genetically stable essential minerals in common bean. Eleven diverse common bean genotypes were grown in three distinct growing environments and 17 essential minerals were analyzed by Inductively Coupled Plasma-Optical Emission Spectroscopy. Genetic control of mineral composition in common bean seed was demonstrated by large (p<0.01) genotypic differences in Ca and Sr contents and moderate genotypic difference was observed in Fe content. Significant influence of genotype and environments (GxE) interaction was observed in the content of all minerals. The ratios between genetic and environmental variances and between genetic and GxE variances indicated the greater influence and stability of genetic factor on the concentration of Ca and Sr in common bean seed. Significant positive correlations among important minerals such as Zn with S, P, Fe and Na and Cu with K, Mg, Ni, P were identified. The stability of genetic effects on Ca and Sr concentration in common bean has been identified in this study. Calcium is one of the most important minerals which regulates many cellular processes and has important structural roles in living organisms. Further studies to characterize Ca physiology in common bean may identify genetic or biochemical markers to expedite breeding common bean with enhanced Ca concentration.
