Annex 1. <strong>Improved</strong> Varieties Released in Tanzania<br />

Tegemeo (2K x 17/B/1)<br />

Open-pollinated (pure line) sorghum variety, selected at Ilonga from a cross with pedigree 2K x<br />

17/B/1. Released in 1986.<br />

Plant characteristics<br />

- height 1.4-1.7 m, semi-dwarf<br />

- tan-colored plant<br />

- medium-sized, semi-upright leaves<br />

- semi-compact, medium-sized panicle, good panicle exsertion, 10-15 cm<br />

- fair tillering, 1-2 tillers/plant<br />

- medium to late duration, 80-85 days to 50% heading, 135-140 days to maturity<br />

Grain characteristics<br />

- creamy white, medium-sized grain<br />

- hard, corneous grain, 3.5 on a 1-5 scale (5=hardest)<br />

- straw-colored glume<br />

- testa (seed coat) absent<br />

- tannin content zero<br />

- milling quality fairly good, 78% flour yield, white flour<br />

- malting quality poor, 20.12 SDU value<br />

Adaptation. Adapted to loam <strong>and</strong> s<strong>and</strong>y-loam soils in intermediate- to long-season areas<br />

(120-150 days) in central Tanzania with average rainfall <strong>of</strong> 450-600 mm. However, it is fairly<br />

susceptible to molding during late rains.<br />

Yield potential. 2.5-4.0 t ha -1<br />

Utilization. Food <strong>and</strong> livestock feed: flour used for porridge (ugali), grain in poultry feed.<br />

Spillover. Potential for spillover to other areas/countries is limited; restricted to the central<br />

plateau <strong>of</strong> Tanzania. Susceptibility to bird damage <strong>and</strong> Striga has limited large-scale adoption in<br />

the Western <strong>and</strong> Lake Zones.<br />
