Abstract: The straight-culmed type of Dendrocalamus sinicus is one of the most important economic bamboo resources in Yunnan Province,China. To protect and develop native germplasm resources of the straight-culmed D. sinicus in Yunnan,the genetic diversity of four straight-culmed provenances of D. sinicus was analyzed based on inter-simple sequence repeat(ISSR) markers for percentage of polymorphic bands(PPB),Neis gene diversity(H),Shannons information index(I) and Neis coefficient of genetic differentiation(Gst). Results showed seven informative and reliable primers with 54 polymorphic loci that were chosen from 80 pre-screened primers. At the population level,PPB was 9.59%,H was 0.036 3,and I was 0.053 6;whereas at the species level,PPB was 73.97%,H was 0.260 0 and I was 0.3921. Also,Gst was 0.863 4. Gst indicated a high degree of genetic differentiation among straight-culmed D. sinicus provenances most likely due to habitat fragmentation and flowering without seed.[Ch,4 fig. 4 tab. 21 ref.]
