ABSTRACT

By the token of its evolution, domestication, and migration (Doggett, 1988), sorghum developed into an important crop plant serving to sustain people in very diverse and often very harsh environments. Basically, sorghum is a warmseason, daylength-sensitive, C4type metabolism plant. However, for almost any feature used to describe the plant, diversity rather than homogeneity is a more fitting characterization. This is linked to the wide environmental adaptation of sorghum. Different sorghum races or cultivars may express adaptation to temperate or tropical climates, high or low altitudes, water logging, or drought stress conditions.
