orghum (Sorghum bicolor (L.) Moench.) belongs to the Poaceae family and is widely cultivated. It is considered to be one of the most important cereal crops in the world. There are about 30 Sorghum species; S. bicolor is cultivated for grain and forage while S.halepense (L.) Pers. (Johnson grass) and S. propinquum (Kunth) Hitchc. are cultivated only for forage. Wild relatives of sorghum include S. bicolor subsp. verticilliflorum (Steud.) de Wet ex Wiersema & J. Dahlb. (common wild sorghum; synonym: S. arundinaceum), Sorghum purpureosericeum (Hochst. ex A. Rich.) Asch. & Schweinf. and Sorghum versicolor (Andersson). Sorghum is an important part of the diet for many of the world’s population. It is mainly consumed as flat bread or porridge. It is also used as a forage crop (ICRISAT 2008) and sweet sorghum is grown to produce sorghum syrup. Sorghum is extremely drought-tolerant, making it an excellent choice for semi-arid and dry areas. Most cultivars are annuals although some are perennial. Sorghum stems may reach over 4 m height, with small grains of 3–4 mm diameter. It is usually grown in clumps. The inflorescence varies greatly in size and shape, ranging from loose drooping branches to a compact-oval shape (IBPGR and ICRISAT 1993). Although it is mostly self-pollinating, protogyny may cause at least 5% natural cross- pollination (Purseglove 1972). The genetic integrity of sorghum accessions is thus maintained by selfing.
