Introduction
In Mali, 57 % of the total
rice area is under rainfed lowland conditions and
contributes abpout 26% to national
rice production. This low performance is due to many abiotic and
biotic constraints. Drought is considered as one of the major abiotic
stresses, which limit rice productivity, and is a major cause of low
yields. Meteorological data of past 30 years showed that rainfall has
decreased by 10 to 30 % in Mali. Consequently, under rainfed lowland
conditions, the yields are reduced due to drought as a result of
insufficient and unpredictable rainfall. To overcome this constraint,
there was a need to combine characteristics of the two cultivated
species namely Oryza glaberrima, the drought resistance of
African rice, and the O. sativa, the productive Asian rice
variety.
