In the Lake Zone, Tanzania, between 2009-2012, 88 decentralized vine multipliers (DVMs) were established by the Marando Bora project. Five years later, the follow up study traced 81 of the DVMs. 40% of the DVMs had sold planting material of Marando Bora varieties in the last year; a further 16% had maintained the improved varieties for own use. The percentages of DVMs retaining different improved varieties were: Polista: 48%; Kabode: 34% Ukerewe: 23%; Ejumula: 12%; and Jewel: 11%. Depending on variety, between 9-21% of DVMs had obtained replacement materials.
