Bambusa multiplex (Gramineae, Bambusoideae), a sympodial bamboo species with pachymorph rhizome was chosen as material for genetic improvement research, considering its wide distribution and strong stress-resistance. In this study, phenotypic traits of five wild populations of B. multiplex in China were investigated and analyzed, genetic diversity was measured by AFLP markers, flowering habit and crossing test were conducted, and callus induction and plantlet regeneration of different explant types w...
