Plantain and banana research at the International Institute of Tropical Agriculture.

Following a global perspective on Musa improvement, the activities of the IITA in banana and plantain research are reviewed. Early work centred on agronomic work and the collection of plantain germplasm; IITA's field gene bank currently holds 113 cultivars of plantain (Musa spp., AAB group) collected from Nigeria, Ghana, Cote d'Ivoire, Cameroon, Congo, Gabon, Burundi and the Philippines. An additional 300 accessions of Musa, ranging from wild species to export banana cultivars, are also held. Much of the field gene bank is duplicated in shoot tip in vitro culture. In 1987, as a response to increasing pest and disease pressure on the crop, bananas and plantains were included in plant improvement programmes and in 1991 a separate programme for these crops was created. Breeding has focused on improving resistance to black sigatoka disease (Mycosphaerella fijiensis) and future objectives include breeding for resistance to banana weevil (Cosmopolites sordidus) and nematodes. Research is also being co

nducted on germplasm enhancement through improved in vitro culture techniques and biotechnology, including the construction of linkage maps, breeding through marker-assisted selection and the mapping of sigatoka resistance loci. Work is currently underway on the assessment of postharvest quality of new disease resistant cultivars, ecosystem analyses of sigatoka diseases in Africa and diagnostic surveys of banana pests in highland bananas of East Africa.
