Description 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.
