The 73 melon（Cucumis melo L.） accessions were identified by 15 morphological markers and 32 CAPS markers in this experiment. Using 15 morphological markers， these melons were classified into 3 categories，when the genetic similarity coefficient was 0.82. The polymorphism rate of CAPS markers were 29.63% in molecular markers. The average polymorphism information content（PIC） was 0.34 with a range of 0.22-0.38. The result
of CAPS cluster analysis showed that the genetic similarity coefficients of these 73 accessions were ranged from 0.50- 0.97. Also， the test materials could be divided into 3 categories， when the genetic similarity coefficient was 0.60. The fingerprinting codes and QR codes had established unique fingerprint for the 73 melon accessions. Each accession could be distinguished from the others. Thus， the germplasm resources could be quickly identified.
