Sierra Leone R ough rice production in Sierra Leone was 430,000 t in 1989 (FAO 1990b). Annual per capita consumption of milled rice was 92 kg in 1979-81 (IRRI 1991) and 84 kg in 1986-88 (FAO 1990a, IRRI 1991). ROKl5 and ROKl6 are rainfed upland varieties that were grown on about 150,000 ha in 1984 (Dalrymple 1986). Preferred varieties have good head rice yield, good grain swelling on cooking, and soft-medium cooked rice (A.O. Adewusi, WARDA, 1990, pers. commun.). Of 24 popular and farmers' field rices, 20 had intermediate AC, two had low AC, and two had high AC. All had intermediate GT, and variable GC (IITA 1985). Thirteen market samples had five with intermediate AC and eight with high AC, and 6-11% protein; eight were parboiled (A. O. Adewusi, WARDA, 1990, pers. commun.). Mean AC of 1988 local rices was 24.3% (Adewusi et al 1989). Samples of irrigated, upland, and tidal swamp varieties were predominantly high AC (Appendix, Table 8). Upland and irrigated rices had low- and intermediate-AC entries, but all tidal swamp rices had high AC, intermediate GT, and hard-medium GC. Grain size and shape were variable, but most were medium-short, medium-slendershaped. Some long-grained rices were included in the samples. ROK3 had harder cooked rice than ROKl6, evident from their GC and Amylograph viscosity. Cooked rice hardness correlated with grain width ( r = –0.40**, n = 44), GC ( r = -0.42**), AC ( r = 0.51**), and alkali spreading value ( r = 0.44**). Grain width correlated with AC ( r = –0.60**, n = 85), and grain length with GC ( r = 0.47**). Tanzania T anzania produced 570,000 t of rough rice in 1989 (FAO 1990b). Annual per capita consumption of milled rice in 1986-88 was 18 kg (FAO 1990a). Twelve popular and farmers' field rices had nine with low AC and GT and three with intermediate AC and GT (IITA 1985). The INGER sample of Salama had high AC, low GT, and hard GC (Appendix, Table 8). It had long, medium-shaped grain. 74 Grain quality evaluation of world rices
Togo R ough rice production in Togo was 29,000 t in 1989 (FAO 1990b). Annual per capita consumption of milled rice was 9 kg in 1979- 81 (FAO 1984) and 11 kg in 1986-88 (FAO 1990a). The two samples from INGER were TGR94 (intermediate AC and GT) and IR46 (high AC and low GT) (Appendix). IR46 had intermediate GT at IRRI and was medium-sized and -shaped. TGR94 had lower Amylograph setback and consistency and softer cooked rice than IR46. It also had short, bold grain. Zambia R ough rice production in Zambia was 12,000 t in 1989 (FAO 1990b). Per capita annual consumption in 1986-88 was about 1.6 kg (FAO 1990a). Ten popular and farmers’ field samples had four varieties with intermediate (AC), four with high AC, and two with low AC, but eight had intermediate GT, one high-intermediate GT, and one low GT (IITA 1985). Seven samples had soft GC and three had medium GC. Two samples were a mixture of red and whitepericarped grains. Kalembwe was one of four basic varieties grown in 1984 (Dalrymple 1986). It had intermediate AC and GT, medium GC (Appendix), and medium, bold grains. Africa 75
