【Abstract】To establish a new high resolution melting analytical method for identification of Lonicera japonica germplasm, the screening of 7 pairs of simple sequence repeats (SSRs) primers, determining the suitable diagnostic primers by the differences of peak pattern and Tm were conducted. Then into the DNA template concentration, annealing temperature and the suitable range of cycle number were investigated. Combined with SIMCA-P software for data processing analysis, the results showed that three main germplasm honeysuckle could be divided by four sets of primers. It provided methodology for improving L. japonica germplasm identification.
