Rice pyriculariose poses a serious constraint to rice production throughout Africa, particularly in those regions subject to drought: more than half of the rice grown in Africa on about 2,500,000 ha (6 million acres) is cultivated in this type of environment. Unfortunately, most of the Asian varieties of rice selected for their resistance to pyriculariose have only a mediocre performance in Africa. If African farmers want to increase their production, they thus need varieties not only resistant to pyriculariose and drought but adapted to their particular soils and climate. One of the main goals of a programme of the International Institute for Tropical Agriculture (IITA) in Nigeria consists in incorporating pyriculariose resistance into all of its rice strains, including both African varieties and highyielding dwarf varieties developed by the International Rice Research Institute (IRRI) based in the Philippines. Seven IITA strains were selected. Variety ITA 212 was distributed in Tanzania after being tested operationally in several African countries. The extensive use of these varieties should enable rice growers to increase their production considerably. Given IlTA's concern with the entire humid and semi-humid inter-tropical zone, its research and training activities revolve around two main axes: the study of agricultural production systems, and crop improvement for cereals (rice, maize), nitrogen-fixing crops (cowpeas, soybeans), and root and tuber crops (yam, sweet potato, cassava, etc.).
