Abstract
Wild Musa has a wide distribution in Guangxi, ranging from Ziyuan county in the north to Fangchenggang and Dongxing city in the south, and from Leye and Tiane county in the west to Wuzhou city in the east. The main distribution can be found in the south, south-west and north-west of Guangxi, where very high mountains with dense vegetation are located. Germplasm collected from different areas showed a great variation in the morphology of buds, fruits and plants indicating their genetic diversity. Based on 25 morphological characters, 18 wild accessions were classified into three sections, namely Eumusa, Callimusa and Australimusa, and were identified as five species of Musa acuminata, Musa itinerans, Musa coccinea, Musa schizocarpa and Musa peekelii. All collected banana accessions are conserved as seeds, suckers/plants or pollen at the Horticultural Research Institute of the Guangxi Academy of Agricultural Sciences (GXAAS). Further characterisation and molecular phylogeny of this germplasm is required to assess their genetic diversity and potential value for banana breeding.
