Abstract: With the fast development of molecular marker and it become the important tool for genetic Breeding of palmea, it is play an important role for shorten the breeding process, accelerated the selection and cultiviation of varities.This paper were mainly summarized the application of molecular marker technique on genetic breeding of palmea, including the genetic diversity and genetic relationships, the molecular marker associated with important traits, genetic linkage map construction. Finally it pointed the future developing directions of molecular marker on palmea breeding.
