Many species are defined in the Musa section within its natural diversification area Southeast Asia. However, their actual number remains debated as botanical characterisation, distribution and intraspecific variability still poorly known, compromising preservation exploitation crop wild relatives of cultivated forms. To address underexplored diversity mainland Asia, at northern edge range, 208 specimens were collected Vietnam, Laos China, mainly belonging to balbisiana , M . itinerans acuminata yunnanensis Data on location, morphology, environment local knowledge recorded, leaf samples for high-throughput genotyping. This study combines geographical, morphological, genomic clarify taxonomic classification. The exhibit highly distinctive morphologies genomes, just they differ ranges life traits. Intraspecific was also observed, although not necessarily morphologically perceptible. Mainland Asia is confirmed a primary centre section. observed only partially represented major international ex situ collections, calling urgent enrichment promotion management procedures, protection these threatened better harness potential breeding programmes. Although considered wild, studied all affected varying extents by human use. subsp. burmannica most strictly forms, with spontaneous interspecific hybrids first described this study. gathered fodder, occasionally dispersed outside endemic zones. per se but populations widely exploited, leading geographically structured diversity. distributed activities. should be regarded domesticated. These various stages, from simple opportunistic gathering true domestication, shed light evolutionary history today’s varieties.
