Overview
Full NameMusa balbisiana
GenusMusa
Speciesbalbisiana
Common NameDH PKW
AbbreviationDH-PKW

The selected 'DH PKW' genotype belongs to the Musa balbisiana species that contributed the B-subgenome to cultivated allotriploid bananas. This is a doubled-haploid (DH) from M. balbisiana 'Pisang Klutuk Wulung' DH-PKW produced through anther culture and spontaneous chromosomes doubling (Assani A at al., 2003). This is the result of a project led by CATAS and BGI in collaboration with CIRAD.

This reference genome was obtained by PAC Bio, Illumina and HI-C technologies and published in the following article:
