Rice genetic improvement for abiotic stress tolerance in Africa.

Abstract

Abstract This chapter presents the major abiotic stresses (drought, salinity, excess water, phosphorus deficiency, iron toxicity and extreme temperatures) that constrain rice production in sub-Saharan Africa and the breeding activities to develop rice cultivars tolerant of these stresses and adapted to local conditions in Africa. The challenges that should be addressed in order to sustainably increase rice productivity in Africa South of Sahara are also discussed.
