[Objective] The research aimed to analyze the genetic diversity of germplasm resources of male Ginkgo biloba L so as to lay foundation for its conservation and breeding innovation. [Method] The improved CATB method was adopted to extracted genomic DNA in the blades of male ginkgo from 11 provinces, the random primers were used for RAPD amplification after primary and second screening, and genetic diversity of germplasm resources of male ginkgo was analyzed by POPGENE software. [Result] 12 pairs of premiers ...
