Aim We aim to reconstruct the phylogeographical history of Musa acuminata subsp. banksii across New Guinea and Australia and to test whether its occurrence in Australia results from ancient natural dispersal or recent human‐mediated translocation. Location New Guinea and northern Australia (Sahul Shelf). Taxon M. acuminata subsp. banksii (F.Muell.) N.W.Simmonds (Musaceae). Methods We generated genome‐wide single nucleotide pol...

Collection and storage of crop wild relative (CWR) germplasm is crucial for preserving species genetic diversity and crop improvement. Nevertheless, much of the genetic variation of CWRs is absent in ex situ collections and detailed passport data are often lacking. Here, we focussed on Musa balbisiana, one of the two main progenitor species of many banana cultivars. We investigated the genetic structure of M. balbisiana across...
