Pisang Klutuk Wulung (PKW) is the Javanese name of a black-stem Musa balbisiana. Klutuk means seed and wulung black. Genebank accessions of PKW were collected in Indonesia, where it is believed to have been introduced, along with Pisang Klutuk.
Its DNA was used to produce a draft genome sequence of Musa balbisiana1 . A doubled haploid form is being sequenced to produce a reference sequence anchored on the species' chromosomes.
Pisang Klutuk Wulung is characterized by a black pseudostem. The leaf's midrib and petiole are also black.
