摘要
In this report, seeds from 91 common bean (Phaseolus vulgaris L.) genotypes were analyzed for their concentrations of protein, starch, and other chemical elements. The first objective of this study was to survey the genetic variability of seed composition in common beans. A second objective was to determine the possible association between seed coat color and seed composition. Significant positive correlation was found between seed starch, cadmium (Cd), and molybdenum (Mo) concentration (R2 = 0.81). Overall, genotypes with black seed coat color displayed the highest levels of minerals tested. We concluded that there is substantial variation for seed composition. Varieties with green coat color had a distinct mineral composition, while extreme accumulation of individual minerals was found to be more prevalent in black seeded varieties. We identified a set of common beans with superior seed mineral composition that could be used to potentially improve nutritional quality of common bean seeds.
