Background Cassava is the most important staple food in Africa after maize Expanding production in drought-prone areas ideal for food security programmes Close to 100 million Nigerians eat cassava – based food at least once a day Still a subsistence crop except for a few countries Features as a suitable commodity to drive Africa’s economic development

Background cont  Drought is one of the major abiotic stresses limiting crop productivity worldwide  As water resources become limiting, the development of drought tolerant crops is important  Cassava performs well in drought prone areas (Okogbenin et al., 2003)

We report drought tolerant and resistant varieties of cassava identified for the maximization of productivity potential in drought-prone areas of Nigeria

Evaluation of varieties from Nigeria and Latin American in drought prone agro-ecology of Nigeria 59 varieties (with 2 checks) were evaluated at Mirjibril, Kano drought prone agro-ecological zones in Nigeria Randomized complete block design

Evaluation of varieties from Nigeria and Latin American in drought prone agro-ecology of Nigeria 3 replications Reaction to major pests and diseases as well as yield and physiological parameters collected over two years

This is the period when physiology data on drought screening were taken at the peak of dry season

This is the period when yield data on drought screening were taken at the onset of rain season
