Plantain has a low natural multiplication rate, making it difficult to expand production. Also, many pests and diseases inhibit optimum production. Between 2003 and 2005, Bioversity International and IITA partnered with the Crops Research Institute (CRI) of the Council for Scientific and Industrial Research (CSIR) of Ghana and World Vision to distribute new plantain and banana cultivars for on-farm testing. Over 2,000 farmers planted small plots of four new hybrids and were trained in rapid macropropagation techniques for clean seed multiplication and other improved agronomic practices. After initial hesitation, farmers embraced the unfamiliar planting material, particularly after observing the vigor and healthy foliage of some of the hybrids. Rapid multiplication technologies were transferred as part of a technology package, including marketing, improved production, and pest management. Changes were also introduced for the postharvest handling (cooking duration) of the fruits. Rapid multiplication continues to be used in Ghana, promoted mostly by extension services and by CRI.
