Nigeria is the second-largest sorghum producer in the world after the United States, with about 6.5 million tonnes a year on roughly 5.8 million hectares. The crop is the cereal anchor of every Sudan and Guinea agroecological zone north of latitude 9.
IAR Samaru sorghum breeding began in earnest under K. O. Adeoti and J. M. Andrews from the late 1960s, targeting striga (*Striga hermonthica*) resistance — the parasitic weed that destroys 30–50% of sorghum yields across the Sudan zone — and brewing-grade endosperm. Two threads run through it.
The first is food sorghum: white-grained, low-tannin varieties for the *tuwo* and *fura* market — SAMSORG 14, 17, 40, 44.
The second is malting sorghum: amber-grained, vitreous-endosperm types that emerged after the 1988 Buhari/Idiagbon ban on imported barley and barley malt forced Nigerian breweries (Nigerian Breweries, Guinness Nigeria, Consolidated Breweries) to substitute. SAMSORG 17, KSV 8 and the later SAMSORG 41 became the basis of the sorghum-malt brewing economy that survives to this day. Guinness Foreign Extra Stout brewed in Nigeria, sold across forty countries, is made almost entirely from Nigerian sorghum.
It is, in the catalogue's narrow sense, a complete breakthrough: the variety, the agronomy, the downstream industrial process, and a durable export industry — held together by an unbroken Nigerian university breeding programme.
