Improving drought tolerance in rice for Africa

G7010.04.01 Improving rice productivity in lowland ecosystems of Burkina Faso, Mali and Nigeria through marker-assisted recurrent selection (MARS) for drought tolerance and yield potential

Lead institute: AfricaRice

The impact of drought due to erratic rainfall and poor water control in rainfed lowland ecosystems affects rice yield in approximately 80 percent of the total rice-growing area in Mali, 67 percent in Burkina Faso and 48 percent in Nigeria.

The Rice Research Initiative (RI) focuses on the rainfed lowland rice ecosystem in these three countries above. It will characterise the drought profiles of the target population of environments in inland river valleys, identify drought traits of interest using novel phenotyping methodologies (which enable efficient separation of genetic and environmental effects), and establish and test a marker-assisted recurrent selection (MARS) scheme to develop better-adapted, drought-tolerant rice.
