ABSTRACT	DNA banding profiles generated by PCR reaction using different lengths of primers were used to study the genetic polymorphism and identities of 30 accessions from three major groups (pakchoi, chingansai, and edible rape) of Brassica rapa ssp. chinensis. Except for one accession later identified as B. juncea, all accessions can be separated into three major clades by applying maximum likelihood method as predicted by morphological taxonomy. Furthermore, the genetic relationships within different cultivar groups, and especially the pakchoi group, were also investigated based on their geography and growth habitat.
