Sorghum (Sorghum bicolor (L.) Moench) is a cereal of remarkable genetic variability, which
makes it difficult to classify. A few names of sorghum are milo, jowar, kafir corn, guinea corn,
and cholam. The plant originated in equatorial Africa and is distributed throughout the tropical,
semi-tropical, and arid regions of the world. The seed or caryopsis of sorghum provides a major
source of calories and protein for millions of people in Africa and Asia. Grain characteristics of
sorghum have been documented by Rooney and Miller (1982). Appearance and quality of
sorghum are affected significantly by genetically controlled characters.
