Sing T.P. | Lutaladio N.B.
Cassava is the most important root crop grown in Zaire, and both the roots and leaves are consumed.Root yields from local varieties are low because of their low genetic potential and susceptibility to major pests and diseases. Research for the improvement of cassava in Zaire was initiated in 1976, and breeding efforts have resulted in the identification and development of high-yielding varieties with field resistance to major diseases under different soil conditions. A source of resistance to mealybug has been identified in both wild and cultivated cassava, and resistance to cassava green mite is available. Cassava germ-plasm screening for leaf HCN content has been started. Agronomic studies have resulted in recommendations to improve cassava production and income at the farm level. A strategy to diffuse improved cassava varieties and cultural practices for adoption by farmers in the absence of an effective national extension service has been suggested.
