Doggett (1988) described sorghum (Sorghum bicolor (L) Moench) as an indigenous
African cereal and traditional food crop. Like other cereals such as barley, maize, rice
and wheat, sorghum belongs to the grass family, the Gramineae (Odibo, Nwanko and
Agu, 2002). Sorghum kernel is considered a naked caryopsis, i.e. kernel losing its hulls or
glumes after threshing (Serna-Saldivar and Rooney, 1995).
