Through a combination of conventional and new approaches, root and tuber improvement programs have developed improved cassava varieties that combine multiple pest and disease resistances with superior postharvest qualities, and improve the yield potential by more than 50%. This new generation of ...

Diagnostic surveys were conducted in 2002 and 2003 in order to provide a comprehensive and detailed assessment of the status of cassava mosaic disease (CMD) in the Republic of Congo (ROC) and to determine if the disease was spreading. In 2002, 105 farmers’ fields were assessed in the four major c...

Objective: Cassava is a crop with largely unexplored and unexplained potentially valuable genetic variability. This study aimed to investigate interrelationship between factors that control cassava yield. Methodology and results: Fourteen quantitative characteristics were assessed in ten cassava ...
