8 local cultivars and 30 wild germplasm accessions were studied by using RAPD and ISSR markers to discuss ramie's molecular background. The result showed 358 strips were amplified by 31 RAPD primers while 266 strips by 18 ISSR primers. The average strips amplified by RAPD and ISSR primers were 11.5 and 14.8, respectively. The genetic relationships were analyzed using unweighted pair-group method of arithmetic average cluster analysis (UPGMA) and the genetic Jaccard similarity coefficients were calculated. T...
