Interpretive Summary: Sorghum is grown around the world and often under harsh and variable environmental conditions. Combined with the high degree of genetic diversity present in sorghum, this can result in substantial variability in grain composition and grain quality. While similar to other cereal grains such as maize and the millets in some aspects, sorghum has many unique compositional traits which impact grain quality and utilization. This chapter reviews the physical structure of the sorghum grain as well as the composition of starch, proteins, lipids, phenolic compounds, vitamins and minerals. Ultimately grain composition is the result of complex interactions between plant genetics, the environment and crop management practices. Thus this chapter also includes a summary of research showing how various factors can impact sorghum grain composition.
