Juliano et al. - 1993 - Grain Quality Evaluation of World Rices

Africa
A
frica produced 10.7 million t of rough rice in 1988 (2.2% of
world's total). In 1986-88, 13.2 million t of rough rice were
available for consumption (FAO 1990a,b). Per capita milled
rice consumption in 1986-88 was 15 kg/yr.
Benin
R
ough rice production in Benin was 8,000 t in 1986-88 (FAO
1990b) and per capita milled rice supply was 9 kg/yr (FAO
1990a). Analysis of nine popular and farmers’ field varieties
showed mostly intermediate AC, intermediate GT, and hard GC (IITA
1985). The only sample from Benin analyzed at IRRI was long, slendergrained
ADNY 11, which had high AC, low GT, and medium GC
(Appendix, Table 8). This may not be the typical rice in Benin, based on
an IITA survey (IITA 1985).
Cameroon
T
he
Republic of Cameroon produced 90,000 t of rough rice in
1989 (FAO 1990b). Annual per capita consumption of milled
rice was 6 kg in 1979-81 (FAO 1984) and 10 kg in 1986-88 (FAO
1990a). IR46, planted to more than 10,000 ha, was the most popular
variety in northern Cameroon in 1983 (Dalrymple 1986). Tainan 5
predominated near Bamenda. The IITA Genetic Resources Unit reported
that of 20 popular rices from farmers’ fields, 17 had high AC,
3 had intermediate AC, 17 had intermediate GT, and most had variable
GC (IITA 1985).
Only two rices from Cameroon, obtained through the International
Network for Genetic Evaluation of Rice (INGER), have been analyzed
