Flowchart for decision making on propagation methods for cassava planting material production. The success of diagram procedures connected by red lines depends solely on the initial material certification as disease free. The lack of such certification results in lack of confidence in the system and may result in the distribution of unhealthy planting material in farmers’ fields. One possibility to ensure clean starting material is that gene banks provide certified plants in vitro. Any cassava seed system (blue arrows) must integrate in-vitro platforms with macro-propagation schemes to offer high-quality abundant planting material continuously to the end-users.
